The A 7B 4-SF121603A is an oil-impregnated bronze flanged bushing with a 0.377 inch bore, 0.502 inch outside diameter, and a length of 0.40625 inch. The flange has a diameter of 0.502 inch and a width of 0.09375 inch. The part is self-lubricating and designed for use in rotating applications. Dimensions conform to tolerances of ±0.005 inch for length and flange diameter, and ±0.0025 inch for flange width.
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.
