The FLURO® production program consists of Rod Ends to DIN ISO 12240 - 4 and Spherical Plain Bearings to DINISO 12240 - 1, Series K and E. Stainless steel, maintenance free and versions with lubrication fittings are available.Where bearings with standard dimensions cannot be used, parts to customer designs are manufactured.
Since many years the FLURO® products have achieved a reputation of high quality and durability. Therefore thedemand within the industrial application market continuously increased. Market observation and customer requestsinitiated the development and design of a Motor Sport product.
Technical research and continuous product development enabled FLURO® to establish a product version exclusivelydesigned for motor sport applications.
On the following pages Rod Ends and Spherical Plain Bearings are introduced, which have already proven itself inMotor Sport applications.
Recently our industrial plant was enlarged and modernized. This means advanced improvements to our logisticsand an enlarged stock of products for faster production and delivery response.
For Rod Ends and Spherical Plain Bearings for the
industrial application sector, please refer to FLURO®'s
An internal play with 'zero' tolerance is achieved through a preloaded bearing. Under normal permissible conditionsand usage a minimal settlement of the bearing components or a minimal tolerance increase at the mating surfacewill take place. This special bearing technology causes a considerably higher bearing life with continuous low internal clearance. However MS-Spherical Plain Bearings are not suited for rotation as well as very high swivel frequency.
Please note that the series GXO..ICR(RR) is not a preloaded bearing version, but the clearance is reduced to a minimal fit.
Surface
The nickel plated housing surface with a high polish finish achieves a sporty appealing design, especially on visiblecomponents. This high-quality surface treatment with high corrosion resistance minimizes the sedimentation of dirtand is easy to clean.
Lubrication
Maintenance Free Rod Ends and Spherical Plain Bearings must not be lubricated. The ball revolves on a PTFE linerincorporated in the Insert.
The Motor Sport steel on steel version should be lubricated with the FLURO® high performance grease FE 3752.This grease can be ordered from FLURO®.
Examination:
Upon customer requirements the parts can be checked against cracks.

The Motor Sport application has its own demand on product and technique. The required task is to create a product which combines high performance and an appealing sporty design. Animated through customers and inclose contact with technicians and university development teams FLURO® developed this MS series. For the belowmentioned applications the technical geometric design in connection with the performance of the bearing becomesimportant. A special emphasis has to be laid on the bearing's composition of inner ring, insert, mating surface andhousing.
A classic application for Rod Ends is the suspensionsystem. Related to it are different load problems suchas vibrations and shocks under radial or axial loads.This dynamic stress demands a technically high qualitybearing.
Depending on the race course and the driving perfor-mance of the driver, different loads can occur on thesteering system.
In addition racing vehicles require a sporty design andappearance. The nickel plated housing with a highpolish finish offers a professional racing look and iseasy to clean from dirt and grease.
For motor cycles Rod Ends and Spherical PlainBearings are used as stabilizers, for rod linkages andsteering devices.

Torque:Because the bearing has 'no play', the internal clear-ance (torque) of the MS parts can be only defined bythe force with which the ball can be moved.
Requirements:The force (torque) with which the ball can be moved ismeasured in Ndm (Newton per decimetre). Herewith abolt with one decimetre length is inserted into the ball's bore and the force to move the ball is measuredwith a spring balance. To neutralise the slip stickeffect before measuring, the ball has to be moved atleast five times the maximum possible distance.Because the 'breakaway torque' will be three timeshigher than the real torque value. The torque rating on the rod ends data sheet in thiscatalogue, is the load during operating process (aftera short period of warm-up time). The torque rating on the spherical plain bearings datasheet in this catalogue refers to the ex factory condi-tion and can increase after being mounted.

Technical Information

Bearing Load ratingsBearing Load ratings are bearing specific data, derivedfrom the characteristics of the materials used. They areused when selecting Spherical Plain Bearings or RodEnds for a particular load, but may have to be reducedin adverse operating conditions.
Static Load ratings Co [kN]
Co indicates the maximum permissible static loadwhich a Rod End at its weakest cross section can withstand without developing permanent distortion.The Co values listed in the tables of this brochure havebeen calculated by using the appropiate material spe-cifications and have been tested on a number of RodEnds during tensile tests carried out at ambient tem-perature. 80% of the yield strength resulting from thetests have been used so that a safety factor of 1.25 isincluded. The static load Co is also used for establishing themaximum axial load which is limited by an additionalbending stress principally due to the method of fastening of the insert. Following are maximum axialvalues (deformation) which have been established bypressure testing:
(1) Fa = Fa, zul = a . Co [kN]
a = <~ 0,4 GXO MSa = <~ 0,2 für GXSW, GXOW MS mounted in a
FLURO® Rod End housinga = <~ 0,1 für GE...EC-NIRO MS
For Spherical Plain Bearings Co indicates the radialload, which does not deform the mating surface permanently. Precondition is the stable configurationof the housing.
Dynamic Load ratings C [kN]
This rating is used to establish the working life ofSpherical Plain Bearings or Rod Ends when underdynamic load conditions. That is to say when theyoscillate, rotate or pivot under load. The values listed inthe table result from multiplying the maximum surfacepressure pmax admissible in gliding movements by theprojected bearing surface. Aproj, whereby a specificload rating is established for each type of Rod End.The established standard values for maximum surfaceload for various combinations of anti friction materialhave been listed in table 1 which allows for movementwhen oscillating.Information: Depending on the material strength of theRod End housing (eg. pages 10 and 11) the static loadmight be lower than the dynamic load.
Due to the use of special materials, FLURO® is able to design high performance bearings, which can operate within a temperature range of minus 50° to plus 720° Celsius / minus 58° to plus 1328° Fahrenheit. This high per-formance bearing can be used in the area of turbo chargers or exhaust return mechanisms. In the area of very aggressive substances such as sand, salt and dust these bearings are highly recommended.They are also very resistant against vibration.

Installation instructions:
Attention: No tolerance or play can be allowed for the shaft when incorporated in the Ball or the Outer Ring whenincorporated in a housing. Through this it is guaranteed that the glide movement arises on the nodular gliding surface only.
When mounting extra precaution has to be taken that the press force does not damage the bearing. The press force should not be initiated via the bearing itself. Thermal installation will reduce the necessary press force.
Axial locking of Spherical Plain Bearings:
When under high static or dynamic axial load, vibration, impacting load changes or high pivoting anglesSpherical Plain Bearings have to be locked axially.
Possible locking methods:- locking through several puncher points - caulking of bearing on the housing through a flanging groove- with locking snap rings- clamped with bushings on the facing surface of the Insert
