Features

SKF Heavy Industrial seals are

• made to order in an unlimited range of

customized sizes to suit existing machine

dimensions,

• available in a wide range of design and

material options to suit application

requirements,

• produced quickly to suit any customer lead

time – including standard, express or

urgent delivery options and

• quick and easy to install, the seals reduce

risk of failure and resultant downtime.

Heavy duty industrial applications, such as

construction equipment, metal, mining,

paper, oil drilling or wind turbines can be

very challenging for radial shaft seals. In

operation, the seals are exposed to a wide

range of temperatures, speeds and abrasive

contaminants. Seals for these applications

feature generally strudy designs and often

large size and come with some special fea-

tures to help improve sealing performance,

reliability and handling.

The Heavy Industrial Seals (HIS) range is

specially developed by SKF to protect large

size bearings under the tough operating

conditions experienced in heavy industrial

applications.

The heavy industrial seals offering

includes metal cased seals (HDS), all-rubber

seals (HS), reinforced all-rubber seals (HSS)

and polyurethane seals (HRS). SKF’s lexible

manufacturing processes of the seals ena-

bles a wide range of dimensions to be man-

ufactured, with no extra tooling or machine

setup time and costs or delays to mainte-

nance timelines. In addition, this SKF service

has no minimum order quantity, so is ideal

for both large and small industrial applica-

tion requirements.

Typical applications

• Steel and aluminium rolling

• Pulp and paper feeders and paper

machine wet section

• Mining and cement machinery

• Traditional energy – coal grinding mills

• Wind turbines

• Tunnel boring machines

• Heavy duty gearboxes

• Special purpose machinery

• Construction machinery

General

SKF metal-cased seals are specially

designed to withstand the extreme condi-

tions encountered in heavy-duty applica-

tions. The seals include the highly engi-

neered and commonly used HDS1, HDS2

and HDS7, as well as designs with additional

excluder lips, such as the HDSA, HDSF,

HDSH. HDS2 and HDS7 seals can be

ordered as a unit in back to back (e.g.

HDSD2) or in tandem (e.g. HDSE2) arrange-

ments. These seals perform exceptionally

well in the very contaminated environment

of metal rolling mills, the pulp and wet sec-

tion of paper mills, mining and construction

machinery and more universal industrial

drive applications.

Size lexibility

SKF metal-cased seals are available in a

wide range of sizes. Seals in customized

dimensions are created as required without

any new tooling, resulting in short lead

times. In addition, the minimum order quan-

tity is just one seal, enabling a lexible solu-

tion for any heavy duty application, no mat-

ter how big or small the job.

The HDS seals are available for all shaft

diameters within the ranges listed in table 5

on page 200. The size tables starting on

page 203 list a selection of sizes. Contact

your SKF sales representative for additional

information.

Ease of installation

SKF’s heavy duty application self-retaining

HDS seals are ideal for use in open housing

bore installations. For housings with cover

plates and axial clamping of the seal into the

housing bore, please refer to the all rubber

SKF seals marked HS and HSS on page 90.

equipped with a heavy-duty metal case and

a stainless steel garter spring.

The HDS1 seal († ig. 1) has a spring

installed in the SKF Springlock groove (†

ig. 11 on page 191). For blind installations,

where spring displacement may go unde-

tected, HDS2 seals († ig. 2) have an SKF

Springcover († ig. 12 on page 191) that

retains the spring in the groove. The HDS1

and HDS2 seals are available with adjustable

or ixed-width spacer lugs († page 190)

The HDS1 and HDS2 seals can be

designed with a PTFE or ECOPUR auxiliary

lip, positioned and directed in either of the

two ways shown in igs. 6 and 7 on page

188 and with optional SKF Bore Tite outer

diameter sealant coating († ig. 13 on page

191).

Nitrile rubber (NBR) is standard for these

seal designs, but both of them are also avail-

able in SKF Duralip (XNBR), SKF Duratemp

(HNBR) and SKF Duralife (FKM).

Metal-cased seals

HDS7

Fig. 3 HDS7

The ingress of water and solid contaminants

is a common cause of bearing failures. To

solve this, SKF developed in its lexible in size

heavy duty HDS radial shaft seals family the

HDS7 seal with enhanced exclusion capabili-

ties († ig. 3). It was originally designed for

grease lubricated bearings in rolling mill

stands, where water and scale are a constant

threat to bearing service life. The HDS7 is

also recommended for use in large gear-

boxes, coal pulverizers and cement grinders

and all other applications where excluding

contamination and protecting the drive train

challenges the sealing system. Customers

have reported that the HDS7 seal is easier to

install and provides longer service life than

common seal designs.

The HDS7 seal features an optimized

non-spring-loaded lip proile, designed to

retain grease and aggressively pump con-

taminants away from the lip. The lip concept

of HDS7 seals also reduces radial loads,

which otherwise can lead to elevated under-

lip temperatures and increased seal wear.

HDS7 seals are installed with the sealing lip

facing the air side. The HDS7 can also be

used in oil lubricated applications in back-

to-back arrangements with a spring-loaded

seal design, e.g. an HDS1 or HDS2 († igs. 1

and 2), in the includer position.

HDS7 seals can also be equipped with a

PTFE or ECOPUR auxiliary lip positioned and

directed as shown in ig. 7 on page 188.

The HDS7 seal is available with a nitrile

sealing lip (NBR) for general use, SKF Dur-

alip (XNBR) for increased wear resistance in

abrasive environments and SKF Duratemp

(HNBR) that combines improved wear

resistance with increased temperature capa-

bility. For certain applications, SKF Duralife

(FKM) can also be speciied. See page 31 for

additional information about different seal-

ing lip materials.

SKF Bore Tite outer diameter sealant

coating (see page 191 ) and spacer lugs (see

page 190) are available as options.




188188


HDSA seals

HDSA seals are designed with an elasto-

meric auxiliary lip in addition to the sealing

lip († igs. 4 to 7). They are generally used

where additional protection from light

contaminants is needed.

HDSA2 is designed with an SKF Spring-

cover for spring retention in blind installa-

tions e. g. in metal rolling mill chocks, while

HDSA1 is designed without an SKF Spring-

cover for industrial drive and gearbox

applications († ig. 12 on page 191).

HDSA is also available with SKF Bore Tite

coating ( see page 191).

HDSA seals are available with sealing lips

made of nitrile rubber (NBR), SKF Duralip

(XNBR), SKF Duratemp (HNBR) or SKF

Duralife (FKM). For shaft diameters up to

1 200 mm (47 in), the standard auxiliary lip

is made of SKF Duralip.

Metal-cased seals

HDSF and HDSH seals

HDS1, HDS2 and HDS7 seals can be

designed with an auxiliary PTFE or ECOPUR

lip to further protect the bearing and sealing

lip(s) from dust particles in heavily contami-

nated environments, for example mining

and cement industries. The lip is then posi-

tioned and directed as shown in ig. 6.

The auxiliary lip is providing strong pro-

tection against solid contamination (ig. 7).

The auxiliary lip is clamped between the

metal case and the rubber seal body without

signiicantly increasing the total seal width.

It has very good wear resistance, can with-

stand dry running and contributes to

improved sealing performance while only

generating a minimal friction torque. The

PTFE auxiliary lip has outstanding chemical

and temperature resistance. The combina-

tion of a PTFE auxiliary lip and a main lip

made of the luoro rubber compound SKF

Duralife creates a particularly effective seal-

ing solution for applications with elevated

temperatures and required seal resistance

against process or cleaning luids.

Special care must be taken to prevent

damaging the PTFE lip during installation.

Refer to instructions in paragraph PTFE

seals on pages 96 and 97.

The letters F and H in the product name

indicate a PTFE or ECOPUR auxiliary lip

design including the lip’s position and direc-

tion; see for example the HDSF2 († ig. 6)

and HDSH2 († ig. 7).

SKF Bore Tite Coating

SKF Bore Tite Coating is optional available as

a water-based acrylic sealant for all SKF

metal-cased HDS seals. The sealant is used

as a coating on the outside diameter of the

seal. For more details see page 191.

HDSD and HDSE seals

HDSD seals († ig. 8) are designed with two

sealing lips facing opposite directions (back

to back arrangement). These seals are typi-

cally used in applications where two luids

must be kept separated e.g. the bearing

lubricant and a process luid. When using an

HDSD seal, it is very important to provide

the means to lubricate the sealing lips. To do

this, the cavity between the sealing lips must

be illed completely with grease prior to

installation.

HDSE seals († ig. 9) feature two sealing

lips facing the same direction (tandem

arrangement). They are typically used when

a back-up seal would otherwise be needed

for retention or exclusion purposes. Like for

HDSD seals, for HDSE seals the cavity

between the sealing lips must be illed with

grease prior to installation so that the seal

functions properly.

HDSD and HDSE seals are equipped with

an SKF Springcover (HDSD2, HDSE2) (†

ig. 12 on page 191). All of them are availa-

ble in nitrile rubber (NBR), SKF Duralip

(XNBR), SKF Duratemp (HNBR) or SKF Dur-

alife (FKM).

HDSD and HDSE seals are available

optional with SKF Bore Tite outer diameter

sealant coating (see page 191 ).

HDSD2

ECOPUR is a thermoplastic

polyurethane (TPU) and has

outstanding mechanical properties like

abrasion resistance against contami-

nants. G-ECOPUR and H-ECOPUR

are hydrolysis-resistant polyurethanes

with similar properties. The size of the

seal will dictate whether G-ECOPUR or

H-ECOPUR is used.

190190


Spacer lugs

Spacer lugs are available for all metal-cased HDS designs to

separate seals in tandem or back-to-back arrangements to provide

space for sealing lip lubrication († ig. 10).

Traditional ixed-width lugs for metal-cased HDS seals are

9,5 mm (0.375 in) in diameter and are available in widths from

3,2 mm (0.125 in) to 12,7 mm (0.5 in) in increments of 1,6 mm

(0.063 in). The ixed-width lug is an available option for all met-

al-cased seals.

All standard adjustable lugs are 9,5 mm (0.375 in) in diameter and

9,5 mm (0.375 in) in width. They can be adjusted to smaller widths in

1,6 mm (0.063 in) increments by removing the steel washers. The

lugs may also be removed entirely. Longer, adjustable lugs, with a

width of 12,7 mm (0.5 in), are available on request, however, it can be

more dificult to reduce their width.

Certain small seal cross sections may require special small diame-

ter lugs, 5,3 mm (0.210 in), with a width range of 1,6 to 3,2 mm

(0.063 to 0.125 in).

The lugs are placed around the heel of the seal in four, six or eight

equally spaced locations, depending on the seal outside diameter

(† table 3).

SKF Springlock

The SKF Springlock is a sealing lip feature that surrounds 270° of the

garter spring diameter († ig. 11). It helps hold the spring in position

during installation and is standard on all HS, HSS seals and spring-

loaded, metal-cased HDS seals.

SKF Springcover

For blind installations, where spring displacement may go unde-

tected, the SKF Springcover († ig. 12) can be speciied. It also

protects the spring from dirt, water and other contaminants. SKF

Springcover is lexible and covers the exposed portion of the stainless

steel garter spring without adversely affecting the spring’s capability.

SKF Bore Tite Coating

The static sealing ability between a metal outside diameter and the

housing bore is somewhat limited. This is particularly the case with

low-viscosity and wetting luids. With this in mind, HDS seals can be

ordered with the optional SKF Bore Tite Coating († ig. 13), a water-

based acrylic sealant. SKF Bore Tite Coating is green in colour, does

not harden and serves to ill small imperfections in the housing bore.

• The coating thickness is 0,03 to 0,07 mm (0.0012 to 0.0028 in)

• The coating compensates for small imperfections in the housing

bore surface. It is recommended for bore surface texture greater

2,5 µm (100 µin) Ra

• The temperatures resistance is up to 200 oC (390 °F)

Media compatibility is very good for oils, greases, aqueous acids and

alkalis, alcohols, glycols. With aromatics, ketones and esters the

coating is not compatible.

HS all-rubber seals

HS seals, available in solid and split execu-

tions, are all-rubber seals, designed without

any re inforcement. They are manufactured

oversized relative to the housing bore dia-

meter and depth to enable proper compres-

sion and stability. A cover plate († igs. 26

and 27 on pages 94 and 95) is required to

compress the seal axially, helping to stabilize

the seal in the housing bore.

A stainless steel garter spring located in

the SKF Springlock groove († ig. 23 on

page 195) provides the appropriate radial

load against the shaft.

For certain applications, HS seals are also

available with an auxiliary lip and / or band

clamp (HSA and HSAC designs). Contact SKF

for more information.

HS seals are available in nitrile rubber

(NBR), SKF Duralip (XNBR), SKF Duratemp

(HNBR) or SKF Duralife (FKM).

Solid execution

Standard solid HS seals can accommodate

shaft diameters starting at 165 mm (6.5 in)

but basic ally do not have an upper size limit.

HS4 seals († ig. 14) have a solid,

all- rubber design and incorporate a spring-

loaded sealing lip. They feature an SKF

Springlock groove († ig. 23 on page 195).

For a proper it in the housing bore, a cover

plate is required († igs. 26 and 27 on

pages 94 and 95).

HS5 seals († ig. 15) have the same basic

design as HS4 seals with the addition of an

SKF Springcover († ig. 24 on page 195) to

hold the spring in place during installation

and protect it from contaminants.

Both designs have a threaded spring con-

nection († ig. 22a on page 195).

General

SKF offers a wide range of all-rubber seals

in customized dimensions for housings with

cover plates and axial clamping of the seal

into the housing bore.

SKF all-rubber seals are specially

designed to withstand the extreme condi-

tions encountered in heavy-duty applica-

tions. The assortment includes the HS and

HSS seals. The HSS seals feature a rein-

forced seal body for improved stability. Both

designs are available as split seals to enable

easy installation without shaft dismounting

in large machinery. These seals perform

exceptionally well in the very demanding

environment of wind turbines, metal rolling

mills, mining and construction machinery

and more universal industrial drive

applications.

Size lexibility

SKF all-rubber seals are available in a wide

range of sizes. Seals in customized dimen-

sions are created as required without any

new tooling resulting in short lead times. In

addition, the minimum order quantity is just

one seal, enabling a lexible solution for any

heavy duty application, no matter how big or

small the job.

For all shaft diameters within the ranges

listed in table 6 on page 201. Also, see the

product tables starting on page 203 for a

selection of sizes. Contact your SKF sales

represen tative for additional information.

Ease of installation

SKF’s heavy duty application axial clamped

all-rubber seals are ideal for use in housing

bore installations with cover plates. For open

housings without cover plates please refer to

the metal cased seals HDS on page 90.

Split execution

In applications where shaft removal is

impractical, HS all-rubber split seals are an

excellent choice. They are simply placed

around the shaft and pushed evenly into the

housing bore with the split at the 12 o’clock

position. A cover plate († igs. 27 and 28 on

pages 95) must be used to compress the

seal axially to stabilize it in the housing bore.

HS split seals perform best with grease or

high-viscosity lubricants. However, low-vis-

cosity lubricants are also suitable if the level

of lubricant is kept below the shaft centre

line, which is particularly important at con-

siderable surface speeds. Split seals are

preferably used on horizontal shafts, but can

also be used on vertical shafts in grease

lubricated applications.

HS6 seals († ig. 17) are designed with a

spring-loaded sealing lip and an SKF

Spring lock († ig. 23 on page 195). They

feature a separ ate loose spring and a hook-

and-eye spring connection for shaft diame-

ters above 455 mm (18 in) unless otherwise

speciied († ig. 22b on page 195). Smaller

sizes of HS6 seals come with a threaded

spring connection. For a proper it in the

Rubber outside diameter seals

housing bore, a cover plate is required

(† igs. 26 and 27 on page 95).

HS7 seals († ig. 18), designed for

grease lubricated applications only, have a

wire controlled sealing lip and are designed

with both an SKF Springlock and SKF

Spring cover († igs. 23 and 24 on page

195). All HS7 seals feature a control-wire

spring connection († ig. 22c on page 195).

The spring is completely enclosed and the

connection is made by running the control

wire into the centre of the spring coil across

the split (butt joint). A built-in spring tension

holds the sealing lip on the shaft. For a

proper it, a cover plate is required († igs.

27 and 28 on pages 95). Due to the unique

design that enables easier installation, a gap

and minor leakage may occur at the joint

even after the cover plate is installed. It is

necessary to place the split at the 12 o'clock

position during installation († ig. 25 on

page 94). HS7 seals do not have the high

sealing characteristics of other HS seals, but

are the easiest to install.

HS8 seals († ig. 18) are designed with a

spring-loaded sealing lip, SKF Springlock,

SKF Springcover († igs. 23 and 24 on page

195) and a hook-and-eye spring con nection

(† ig. 22b on page 195) for shaft diam eters

above 455 mm (18 in). Smaller sizes of HS8

seals come with a threaded spring connec-

tion. The spring is entirely enclosed except

for a small portion on either side of the split.

HS8 seals provide the most effective sealing

performance of all split HS seals and are the

preferred design for retaining low-viscosity

lubricants and for water exclusion. HS8 seals

perform best on horizontal shafts, but can

also be used on ver tical shafts provided they

are not looded with lubricant.

More information on spring connections

for split seals can be found on page 195.

HSS reinforced all-rubber seals

HSS seals constitute a range of seals with a

variety of design following the same design

standard and designation system as the HS

assortment. Additional features are the

reinforced seal body and optional lubrication

grooves ig. 20 at the back of the seal to

allow re-greasing between the sealing lips

in back-to-back or tandem installations of

two HSS seals.

HSS4 and HSS5 are solid, HSS6 and

HSS8 are split seal executions. HSS5 and

HSS8 are featured with the SKF Springcover

(† ig. 24 on page 195). For seals with

lubrication grooves the designation includes

the sufix G (e.g. HSS5G).

HSS seals are available in nitrile rubber

(NBR), SKF Duratemp (HNBR) or SKF Dura-

life (FKM) for all shaft diameters within the

ranges listed in matrix 2 on page 180. Also

see the product tables starting on page

203. for a selection of sizes. Additional

please refer to the unsurpassed size

lexibility of HSS seals, customized dimen-

sions without any new tooling and minimum

order quantity of one seal only. Contact your

SKF sales representative for additional

information.

HSA7, HSA8, HSA7C, HSA8C

HSA7 and HSA8 are speciically designed for

the harsh conditions in the very slow rotat-

ing horizontal grinding mills in cement and

mining industries. The seals feature a

stronger shaft interference than HS7 and

HS8 seals for an improved lubricant reten-

tion at very low speeds and an additional

auxiliary dust lip to keep the heavy dust con-

tamination in the application out of the

bearing.

HSA7C and HSA8C seals are equipped

with an outer diameter retention ring to

simulate the outer diameter interference in

radially open housing bores († ig 21)

HSA7 seals († ig. 21) is designed for

grease lubricated applications only, have a

wire controlled sealing lip and are designed

with both an SKF Springlock and SKF

Springcover († igs. 23 and 24 on

page 195).

For a proper it, a cover plate is required

(igs. 26 and 27 on page 95). Due to the

unique design that enables easier installa-

tion, a gap and minor leakage may occur

at the joint even after the cover plate is

installed. It is necessary to place the split at

the 12 o’clock position during installation

(† ig. 24 on page 92).

HSA7 seals do not have the advanced

sealing characteristics of other HS seals,

but are the easiest to install.

HSA8 seals are designed with a spring-

loaded sealing lip, SKF Springlock, SKF

Springcover († igs. 23 and 24 on page

195) and a hook-and-eye spring connection

(† ig. 22b on page 195). The spring is

entirely enclosed except for a small portion

on either side of the split.

HSA8 seals provide the most effective

sealing performance and are the preferred

design for retaining low-viscosity lubricants.

Spring connections for split seals

There are different ways to connect the stainless steel garter springs

of HS and HSS split seals. A threaded spring connection († ig. 22a)

is used for all solid HS and HSS seals as well as the split HS6 / HSS6

and HS8 / HSS8 seals for shaft diameters ≤ 455 mm (18 in). A hook-

and-eye spring connection († ig.22b) is used for HS6 / HSS6 and

HS8 / HSS8 seals for shaft diameters > 455 mm (18 in). HS7 seals

feature the special control-wire connection († ig.22c), are only to

be used for grease applications when the other spring connections

cannot be installed.

SKF Springlock

The SKF Springlock is a sealing lip feature that surrounds 270° of the

garter spring diameter († ig. 23). It helps holding the spring in posi-

tion during installation and is standard on all HS and HSS seals.

SKF Springcover

For blind installations, where spring displacement may go unde-

tected, the SKF Springcover († ig. 24) can be speciied. It also pro-

tects the spring from dirt, water and other contaminants. SKF

Springcover is lexible and covers the exposed portion of the stainless

steel garter spring without adversely affecting the spring’s capability.

HRS seals

General

HRS seals from SKF were specially designed

to cope with the harsh conditions that wind

turbine main shafts face. They offer lubricant

retention and contamination exclusion to

reduce the risks of lubrication or contami-

nant-related bearings failures and their con-

sequences, such as production downtime

and repair costs. These high performance

radial shaft seals can deliver signiicantly

extended service life and help operators to

reduce maintenance costs and ultimately

increase reliability. These seals can also be

used for other heavy duty applications.

Beneits and features

• Extended service life due to high abrasion

resistance

• Reduced bearing failures related to

contamination

• Resistance against hydrolysis, UV radiation

and ozone due to H-ECOPUR and

G-ECOPUR material

• Increased reliability

• Facilitated up-tower retroits

• Reduced OPEX during machine life

• Easy installation

• Customization of seal size thanks to

lexible manufacturing process

Easy up-tower usage

The split seals are single packed

and designed to fulill the needs in the

wind aftermarket. Each package con-

tains a seal with the garter spring and

an installation guide. To allow for easy

handling and transportation for large

diameter seals, these seals are folded.

HRS seals

HRS and HRSA radial shaft seals

These large diameter radial shaft seals

(† igs. 25 and 26), are designed to protect

large size bearings in grease lubrication and

low pressure differentials. A lexible manu-

facturing process allows a degree of custom-

ization to the seal dimensions to help meet

unusual requirements.

HRSA seals († ig. 26) feature an addi-

tional auxiliary lip to protect the seal and the

application against contamination from the

environment.

HRS and HRSA seals feature a garter

spring that stabilizes the sealing lip,

increases the lip followability (DRO and

STBM) and maintains the sealing function

even in alternating operating temperatures.

The seals are designed to secure the garter

spring inside the spring groove once the

seals are installed.

Solid seals feature an endless garter

spring, while split seals feature an open con-

nection that is closed during seal installation.

Material and manufacturing

ECOPUR is a thermoplastic polyurethane

(TPU) and has outstanding mechanical

properties like abrasion resistance against

contaminants.

G-ECOPUR and H-ECOPUR are hydroly-

sis-resistant polyurethanes with similar

properties.

The size of the seal will dictate whether

G-ECOPUR or H-ECOPUR is used.

G-ECOPUR

Standard seals are made of G-ECOPUR,

which is a casted polyurethane elastomer.

This material has outstanding wear

resistance and increased stiffness compared

to rubber materials († diagram 1).

Increased stiffness allows for easier han-

dling and minimizes the risk of installation

failures like bending the sealing lip or losing

the garter spring.

CNC manufacturing process

Featuring proprietary software and

high-precision cutting tools, the SKF SEAL

JET manufacturing system uses Computer

Numerical Control (CNC) technology to

machine polymeric seals quickly († page

56). The system machines a seal from a

semi-inished tube of the selected material.

TBM (Tunnel Boring Machine) seals protect-

ing the cutter head bearing from heavy con-

tamination (sand, rock, water). The seals can

also handle different misalignments and

pressure steps. One beneit of the SKF seals

are the split version – during the mainte-

nance they can be welded on site and with-

out the need to remove the shaft, therefore

the downtime can be reduced signiicantly.

SKF can manufacture a wide variety of

seal proiles with different materials and

sizes with ist industry-leading SKF SEAL JET

production system (see details on page 56).

machined proiles, refer to publication
