A 7B 7-S403802 is an oil-impregnated bronze thrust washer with an inner diameter of 1.265 inches and an outer diameter of 2.375 inches, designed for self-lubricating axial load applications. The washer has a thickness of 0.0625 inches (1/16 inch), consistent with the S-series specification for this dimension. Dimensions reflect the stated tolerances: inner diameter to ±0.005 inch and outer diameter with a tolerance of +0.015 inch, -0 inch for sizes over 1.500 inch, though the exact tolerance for this specific O.D. is inferred from the general table. The material is sintered bronze, engineered for maintenance-free operation.
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.
