Sintered thrust washers in the S series are made of oil-impregnated bronze and are self-lubricating. The part A 7B 7-S283404 has an inner diameter of 0.8905 inches, an outer diameter of 2.125 inches, and a thickness of 0.125 inch. Tolerances for inner diameter are ±0.005 for sizes over 1.253 inch and ±0.010 for outer diameter over 1.500 inch up to 3.000 inch.
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.
