This 608-2RS miniature ball bearing is made of chrome steel and has rubber seals. It has an 8 mm inside diameter, a 22 mm outside diameter, and a 7 mm depth. The bearing has deep groove geometry for supporting both radial and axial loads and high speeds. The races are made of chrome steel for durability and resistance to deformity under heavy loads. Rubber seals on both sides of the bearing help retain lubricant and exclude contaminants. The static load rating is 141 kgf and the dynamic load rating is 336 kgf. The maximum speed with oil lubrication is 40,000 revolutions per minute (rpm). This deep groove ball bearing is used in applications such as skateboards and rollerblades, among others.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

Tolerance level

/ CLN - Equivalent to ISO tolerance class 6X for metric tapered roller bearings with reduced width tolerances.

/ CL0 - equivalent to ISO0 level tolerances for inch tapered roller bearings.

/ CL3 - equivalent to ISO3-class tolerances for inch tapered roller bearings.

/ CL7A - tapered roller bearings in line with the standard configuration of the differential bearing.

/ CL7C - meet the differential bearing configuration special standard tapered roller bearings.

/ P4 - Size and rotation accuracy in line with ISO4 tolerance (P5 accuracy).

/ P4A - dimensional accuracy in line with ISO4 tolerance, rotation accuracy equivalent to AFBMA standard ABEC9 level.

/ P5 - dimensional rotation accuracy to ISO5 level tolerance (accuracy higher than P6).

/ PA9A - Size and rotation accuracy equivalent to AFBMA standard ABEC9 level.

/ PA9B - Dimensional accuracy equivalent to the AFBMA standard ABEC9 level, the rotation accuracy higher than the PA9A.

/ SP - dimensional accuracy of about P5, rotation accuracy of about P4.

/ UP - The dimensional accuracy is about P4 and the rotation accuracy is higher than P4.
