This RM2-2RS bearing is a sealed 3/8-inch V-groove ball bearing. It is a single-row bearing for supporting radial loads and has a 6,500 revolutions per minute (RPM) limit with greased lubrication. This bearing is sealed to keep lubricant in and contaminants out. The RM2-2RS is a V-groove bearing that is suitable for linear motion applications where the bearing runs along a rail or track.

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.
