The A 7B 4-P136 is a bronze bearing with an inner diameter of 0.188 inches, an outer diameter of 0.253 inches, and a width of 0.468 inches. It is made from oil-impregnated bronze, which provides self-lubricating properties, reducing the need for additional lubrication in applications. This bearing is designed to minimize friction between moving components, thereby enhancing the longevity of rotating parts. The dimensional tolerances for the inner and outer diameters are specified, ensuring precise fit and function in mechanical assemblies. This product is suitable for applications requiring reliable performance in reducing wear and maintaining alignment of shafts and axles.
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.
