The SDP/SI Commercial Sintered Bronze Sleeve Bearing, part number A 7B 4-P102, features an inner diameter (I.D.) of 0.188 inches and an outer diameter (O.D.) of 0.253 inches, with a width of 0.243 inches. This bearing is constructed from oil-impregnated bronze, providing self-lubricating properties that enhance its performance in various applications. The dimensional tolerances are specified as I.D. +0.001/-0.000 inches and O.D. +0.000/-0.001 inches, with a length tolerance of ±0.005 inches. This product is suitable for applications requiring durable and low-friction bearing solutions.
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.
