Oil-impregnated bronze thrust washers in the S series are self-lubricating components designed for axial load applications. The part A 7B 7-S644806 is listed with an inside diameter of 2.011 inches and an outside diameter of 3.000 inches, with a thickness of 3/16 inch (0.1875 inch). Tolerances for inside diameter are ±0.010 inch for sizes over 1.253 inch, and outside diameter tolerances are +0.020 inch, -0 for sizes over 3.000 inch. The material is oil-impregnated bronze, providing self-lubricating properties without external lubrication.
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.
