A 7B 4-GP0812 is a sintered, oil-impregnated bronze plain bearing with a 0.251 inch bore, a 0.377 inch outer diameter, and a length of 0.375 inch. It is self-lubricating and designed for low-friction rotational applications. The part is a member of the G Series, which includes both plain and flanged variants, and features a tolerance of ±0.005 inch on length and ±0.001 inch on bore, ±0.001 inch on outer diameter. The bearing is intended for use where maintenance-free operation is required and no external lubrication is applied during service.
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.
