A 7B 7-S644804 is an oil-impregnated bronze thrust washer with an inside diameter of 2.011 inches, an outside diameter of 3.000 inches, and a thickness of 0.125 inch. It is self-lubricating and designed for axial load applications. The part is part of the S series, which features tolerances specified by bore and outer diameter ranges: inside diameters over 1.253 inches and up to 2.502 inches have a tolerance of ±0.010 inch, and outside diameters over 3.000 inches have a tolerance of +0.020, -0 inch. The washer is manufactured from sintered bronze and requires no 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.
