An ABEC 3 precision ball bearing made of 440C stainless steel, with a 0.3125 inch bore, 0.5000 inch outer diameter, and 0.1094 inch width, designed for low-friction rotational support. The bearing is double-shielded and lubricated with Beacon 325 commercial grease. It has a dynamic load rating of 60 lbf and a static load rating of 22.0 lbf.
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.
