The A 7B 4-SF162405 is a flanged, self-lubricating sintered bronze bearing with a 0.625 in. inner diameter, 0.753 in. outer diameter, and 0.625 in. length, featuring a 0.940 in. flange diameter and 0.1875 in. flange width. The bearing is made of oil-impregnated bronze and is designed for low-friction, maintenance-free operation. Dimensional tolerances are specified as ±0.005 in. for the flange diameter and ±0.0025 in. for the flange width, with a length tolerance of ±0.005 in. The outer diameter tolerance applies as ±0.0015 in. for sizes over 1-1/4 in., but this part falls below that threshold.
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.
