The WJB 6200-2RS series deep groove ball bearing is a double-sealed ball bearing and has a single-row deep-groove geometry for high speeds and supporting both radial and axial loads. Seals on both sides of the bearing fasten to the outside ring and extend over the rolling elements to make contact with the inside ring, keeping out contaminants such as dirt and grime. The seals also hold in a high-quality lubricant applied at manufacture that will last the entire lifetime of the bearing, making it maintenance free. This WJB 6200-2RS series deep groove double-sealed ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy and stiffness at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, 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.
WJB Bearings, Inc. manufactures various types of bearings and components including ball and roller bearings, bronze bushings, and sprockets and chains. The company, founded in 1992, is based in City of Industry, CA.
