R2ZZ Inch Size Miniature Ball Bearings Dimensions

R2ZZ Inch Size Miniature Ball Bearings Dimensions 1/8" x 3/8" x 5/32" R2ZZ Shielded Ball Bearing, this is a popular size that could be used in many applications, the inner diameter is 1/8" inch, outer diameter is 3/8" inch and the width is 5/32" inch, each bearing has 2 metal shields to protect the bearing from dust or any possible contamination, also bearing is pre-lubricated with grease.

Rolling ball 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.
