WJB 6309-ZZ Deep Groove Ball Bearing, Double Sheilded, Metric, 45mm ID, 100mm OD, 25mm Width, 11900lbf Dynamic Load Capacity, 7200lbf Static Load Capacity

The WJB 6300-ZZ series deep groove ball bearing is a double-shielded ball bearing and has a single-row deep-groove geometry for high speeds and supporting both radial and axial loads. The bearing is shielded on both sides for additional protection from debris and other contaminants. This WJB 6300-ZZ series deep groove double-shielded 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.
