The S99BP3-PB102007 is an ultra precision bronze bearing with an inner diameter of 0.1564 inches, an outer diameter of 0.3126 inches, and a width of 0.1094 inches. It is made from porous sintered bronze and is vacuum-impregnated with oil, providing self-lubrication according to MIL-L-6085 standards. This bearing is designed to be an economical replacement for ball bearings and is dimensioned for interchangeability with comparable ball bearings. The outer diameter is concentric to the bore within 0.0002 inches, and the faces are square to the bore within 0.0003 inches. Special bores and outer diameters, as well as other lubricants, are available upon special order. The load speed rating varies based on specific configurations, with some rated up to 50,000 lbf x rpm.
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.
