A 7Y 7-087 is a hardened stainless steel washer used as a component in complete thrust bearing sets, with a thickness of 0.093 inch and an outer diameter corresponding to the 7/8 inch bore size of the matched bearing. It is designed for use with the A 7Z 7-087 thrust bearing, which features 440C stainless steel balls and a nylon retainer rated to 250°F maximum. The washer is made of 410 stainless steel hardened to Rc 38-42.
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.
