SR8-ZZ Stainless Steel Miniature Ball Bearing 1/2x1-1/8x5/16

SR8-ZZ Radial Stainless Steel Miniature Ball Bearing Shielded and pre-lubricated with Grease

The SR8ZZ is a precision stainless steel miniature ball bearing that’s double shielded on both sides, and pre-lubricated with grease. It’s a top-notch ball bearing that’s made of 440C quality stainless steel that allows low noise/vibration, high precision, high and stable performance, long service life, and resistance against corrosion and also heavy loads. This model is popularly used in marine equipment, chemical instrument, boat, food packing, food processing, liquid transmission, electrical, household appliances, combustion engines, roller skates, and other types of machinery

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 and Shielded bearings are lubricated with oil or grease in the bearing factory, while open 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, electric motors, CNC machinery, trucks, mining equipment, train, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
