Oil-impregnated bronze thrust washers of the S series are self-lubricating components designed for axial load applications. They are available in inch dimensions with I.D. tolerances of ±0.005 up to and including 1.253 inch and ±0.010 over 1.253 inch, and O.D. tolerances of ±0.010 up to and including 1.500 inch, +0.015/−0 over 1.500 inch up to 3.000 inch, and +0.020/−0 over 3.000 inch. The series includes variants with I.D. of 1.2550 inch and O.D. of 3.3120 inch, as listed in the catalog.
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.
