A 7Z31-PB0375B is a pillow block-mounted, self-aligning sintered bronze bearing with a 3/8 inch bore, designed for light-duty rotational applications. The bearing housing is made of sintered aluminum and supports radial loads up to 10,180 lbf at a maximum speed of 220 rpm. It self-aligns within ±5° and operates between -20°F and +200°F. The overall dimensions are 1-1/8 inches in height, 2-1/4 inches in length, and 7/16 inches in width, with a mounting hole distance of 1-3/4 inches and a flange hole diameter of 1/4 inch.
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.
