The General 20000 series Extra Light series ball bearing is a double-shielded, single-row bearing for supporting radial loads. Its light bearing structure is for use in limited space applications or for average loads. The bearing is shielded on both sides for additional protection from debris, and other contaminants. This 20000 Series Extra Light Inch series 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.General Bearing Corporation (GBC) manufactures ball bearings, roller bearings, and other bearing components under the Hyatt and The General brands. The company, founded in 1958, is headquartered in West Nyack, NY, and meets International Organization for Standardization (ISO) standards for quality assurance.
