The A 7B 4-SF324408 is an oil-impregnated bronze flanged bearing with a 1.002-inch inner diameter, 1.378-inch outer diameter, and 1-inch length. The bearing includes a flange with a diameter of 1.625 inches and a flange width of 0.1875 inches. It is self-lubricating and designed for applications requiring low friction without external lubrication. Dimensions are specified with tolerances of ±0.005 for length and flange diameter, and ±0.0025 for flange width. The outer diameter tolerance for sizes over 1.25 inches is ±0.0015. The material is sintered bronze, consistent across the S-series flanged bearings.
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.
