ABEC 5 precision ball bearings made of 440C stainless steel, designed for low-friction rotation in mechanical systems, are available in flanged configurations with radial play of 0.0002 to 0.0005 inches. The S9912Y-E1831FS2M variant corresponds to the 1831 bearing code, with a 0.125-inch bore, 0.375-inch outer diameter, 0.125-inch width, and 0.023-inch flange width. It is double-shielded and lubricated with grease meeting MIL-PRF-23827C. Dynamic load rating is 81 lbf, static load rating is 34 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.
