A 7B 7-S202004 is an oil-impregnated bronze thrust washer with an inside diameter of 0.628 inches, an outside diameter of 1.25 inches, and a thickness of 0.125 inch, designed for self-lubricating axial load applications. It is part of the S-series of sintered thrust washers manufactured from porous bronze that retains lubricant. The part conforms to the dimensional tolerances specified for the series: inside diameter tolerance is ±0.005 inch for sizes up to and including 1.253 inch, and outside diameter tolerance is ±0.010 inch for sizes up to and including 1.500 inch. The washer is intended for dry or low-lubrication conditions where maintenance-free operation is required.
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.
