CH Specifically designed for applications -A- where space limitations are a primary
consideration and shafts are relatively
0A B large. Available with metal shields or
Buna N seals. The 6000 series is
} capable of withstanding radial and thrust loads within the limitations of
their ball complement. The conrad construction of the R series enables these bearings to take a thrust load as well as a radial load. The well designed ball complement and selection of retain-ers permit use of this series in high speed motor applications. This series is produced open, shielded or sealed. Shield and sealed bearings are made slightly wider as shown in the dimen-sion table. Metric dimensions are in millimeters.
Designed to be dimensionally interchangeable with standard domestic inch series bearings. By using 52100 steel and holding dimensions to ABEC 1 tolerances, this series offers economy with electric motor quality. Close tolerance and improved ball comple-ment allow an increased load capacity. This series is available with shields and seals. Metric dimensions are in millimeters.

For Electric Motors Single row deep groove ball bearings have deep uninterrupted raceways and a high degree of conformity between balls and raceways. This enables them to carry axial loads in both direc-tions, in addition to radial loads, even at high speeds. Bearings with shields or seals at both sides are filled with a grease which has good rust inhibiting properties suitable of operating tempera-tures of -22 to +230 degrees Fahrenheit. All bearings have a pressed cage of sheet steel and are available either plain, shields on both sides (2 Z), or two rubber seals on both sides (2 RS). All dimensions are in millimeters.
Deep Groove 6200 Series Metric
This deep groove, conrad construction is specifi-cally designed to provide maximum performance by means of precise ball complement selection. The honed raceways offer a perfectly balanced bearing capable of operating under straight radial, thrust or combination loads. This series is available with shields. Buna N seals, or locating rings. Sealed bearings may be obtained with either low or high starting torques. Radial clear-ance is selected in accordance to applications ranging from C2 - CO - C3 - C4 fits. Metric dimensions are in millimeters.

The 6000 series is capable of withstanding radial and thrust loads within the limitations of their ball complement. The conrad construction of the R series enables these bearings to take a thrust load as well as a radial load. The well designed ball complement and selection of retainers permit use of this series in high speed motor applications. This series is produced open, shielded or sealed. Shield and sealed bearings are made slightly wider as shown in the dimension table. Metric dimensions are in millimeters.
These popular bearings are used in a wide range of applications such as motors, pumps, etc. Designed to carry both radial and axial loads. Double shielded bearings have metal shields on the sides. Double sealed have two contact seals made out of synthetic rubber. Metric dimensions are shown in millimeters.

These stainless steel bearings are semi-precision unground type. The 316 type stainless bearings are ideal for hostile environments and wash down applications where the load is too heavy for plastic bearings. Type 316 stainless is non-magnetic and can be run without lubrication at slow speeds. Type 316 stainless provides greater corrosion resistance over 440 type stainless. Cage is made of a polymer. Metric dimensions are in millimeters.

ER Series ball bearings, an industry standard, are used in demanding applications such as: cardboard/packing machinery, paper/printing machinery, carpet tufting machinery, general conveying equipment, pumps, blowers. These bearings feature exclusive heavy duty "DU seals which are permanently sealed and prelubricated for long life. "DU seals feature a steel trash guard combined with the inner ring labyrinth groove provide superior protection in wet/moist environments. These bearings come with two lubrication holes for regreasing, two knurled cup point set screws set 120 degrees apart offer excellent resistance to loosening under vibratory conditions. They are made of fully ground, SAE 52100 chrome alloy steel races featuring a black oxide finish for added corro-sion resistance and are available with low-torque seals (SFR).

ER Series ball bearings, an industry standard, are used in demanding applications such as: cardboard/packing machinery, paper/printing machinery, carpet tufting machinery, general conveying equipment, pumps, blowers. These bearings feature exclusive heavy duty "DL" seals which are permanently sealed and prelubricated for long life. "DL" seals feature a steel trash guard combined with the inner ring labyrinth groove provide superior protection in wet/moist environments. These bearings come with two lubrication holes for regreasing, two knurled cup point set screws set 120 degrees apart offer excellent resistance to loosening under vibratory conditions.

This new concept in thrust bearings provides superior performance and economical characteristics. The unique design of the molded nylon retainer captures the balls in precision molded pockets assuring smooth free turning and quiet operation. The nylon retainer is lightweight, provides natural lubricity and is corrosion resistant. Balls are precision grade 100 tolerance +/-.0001, 4-.0025mm. The thrust washers are hardened steel providing high strength to wear ratio for long life. Available with steel or stainless steel balls. Washers are included with bearing.
Note: Dimension D tolerance for .050 and .062 is +1- .003, .125 is +1-.005.
Cylindrical Rollers
Cylindrical roller thrust bearings have a comparatively large contact area between the roller and raceway. They can support greater loads and accommodate much more shock than ball thrust bearings of a similar size. Cylindrical roller thrust bearings are suitable for medium to heavy-duty applications with high thrust loads and low operating coefficient of friction requirements. The .032" thrust washer is punched from steel, through hardened and polished. These washers should be fully supported on their entire abutment surface. The .126" thrust washers are made from bearing steel. The raceways are ground while the bore and outside diameter are machined. Washers sold separately from bearings.
Note: For oil lubrication use 25 percent of value with grease lubrication.
