The A 7B 4-SF121603 is a flanged, oil-impregnated bronze bearing with a 0.377-inch inner diameter, a 0.502-inch outer diameter, and a length of 0.375 inch. It features a flange with a diameter of 0.502 inch and a width of 0.116 inch. The bearing is self-lubricating and designed for inch-size applications. Dimensions are specified with tolerances of +0.000 / -0.001 inch for bore and outer diameter, ±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.
