Caged needle roller bearing for hardened shafts with a 1.0000 inch bore, 1.2500 inch outer diameter, 0.500 inch width, and maximum speed of 10,000 rpm when oiled; dynamic load rating of 2833 lbf and static load rating of 4294 lbf. Made with case-hardened steel cup, 52100 hardened chrome steel needles, and low carbon steel cage. Requires shaft surface hardness of Rc 58 minimum or use with inner race. Designed for high load capacity and low friction in compact applications.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
