A 7M 7-093ST is a retainer and balls component for a thrust bearing set, consisting of 440C stainless steel balls hardened to Rc 58-65 and a molded nylon retainer rated for maximum 250°F. It is designed for use with the A 7Z 7-093ST thrust bearing, which has a 15/16 inch bore, 1-9/16 inch outer diameter, and 1-1/4 inch washer thickness, and supports a load rating of 268 lb at 15 rpm and 143 lb at 100 rpm. The nylon retainer is non-metallic and non-conductive, enabling low-friction operation while maintaining ball alignment under axial loads.
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.
