This R6-2RS 3/8x7/8x9/32-inch miniature ball bearing has a single-row deep groove geometry for high speeds and supporting both radial and axial loads. The bearing is made of chrome steel for durability and resistance to deformity under heavy loads, and has rubber seals on both sides to keep lubricant in and contaminants out. It is suitable for in electric motor applications. These bearings come in a pack of 10.

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.
