A 7B 4-P023 is a sintered, oil-impregnated bronze plain bearing with an internal diameter of 0.187 in, an outer diameter of 0.4405 in, and a length of 0.187 in, designed for self-lubricating applications. The bearing is configured for inch-sized components and maintains dimensional tolerances of +0.001 in / -0.000 in for the bore, +0.000 in / -0.001 in for the outer diameter, and ±0.005 in for length. The part is part of the standard P series of self-lubricating bronze 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.
