A 7B 7-S564204 is an oil-impregnated bronze sintered thrust washer with an inside diameter of 1.765 inches and an outside diameter of 2.625 inches, as listed in the S series catalog. The part is self-lubricating and designed for axial load applications. Tolerances for inside diameter are ±0.0025 inch, and outside diameter tolerances for sizes over 1.500 inches and up to 3.000 inches are +.015, -0 inch, which apply to this part. The thickness is not explicitly stated but is consistent with the 1/8 inch (0.125 inch) dimension specified for similar variants in the series. The washer is manufactured from self-lubricating bronze material without external lubrication requirements.
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.
