A 7B 7-S201902 is an oil-impregnated bronze thrust washer with an inside diameter of 0.628 in, an outside diameter of 1.1875 in, and a thickness of 0.0625 in. It is self-lubricating and designed for applications requiring low friction and no external lubrication. The part conforms to the S series specifications, with in-stock dimensions matching the tolerances: ID tolerance ±0.005 for diameters up to 1.253 in and OD tolerance +0.015/-0 for diameters over 1.500 in and up to 3.000 in. The washer is made from sintered bronze and is intended for thrust load applications in rotating assemblies.
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.
