A 7Y 7M0512 is a hardened stainless steel thrust washer, 1.27 mm thick, with an outer diameter of 12 mm and an inner diameter of 5 mm, designed for use in metric thrust bearing assemblies. It is paired with 440C stainless steel balls and a molded nylon retainer in complete bearing sets. The washer is hardened to HRC 38...42 and supports dynamic load ratings of 218 N at 100 rpm. The washer is part of a series where all variants share the same material and hardening specifications.
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.
