10 Shielded Bearing R1212ZZ 1/2 x 3/4 x 5/32 inch Ball Bearings

This R1212ZZ ball bearing is made of chrome steel and has metal shields. It has a 1/2" inside diameter, a 3/4" outside diameter, and a 5/32" 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. Metal shields on both sides of the bearing help retain lubricant and exclude contaminants. The bearing is lubricated at the factory with grease. This deep groove ball bearing is used in applications such as yo-yos and radio-controlled (RC) vehicles, 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.
