The A 7M 7-043 is a nylon retainer and ball assembly for a thrust bearing set, containing seven hardened S.A.E 1018 steel balls with a load rating of 190 lbf at 100 rpm and 101 lbf at 15 rpm. It is designed for use with a 7/16 inch bore, 7/8 inch outer diameter, and 21/32 inch total thickness, paired with a CR1075 steel washer hardened to Rc 59-61. The retainer is molded nylon rated to 250°F maximum. The complete bearing set includes a washer and balls compatible with the D787 P5-56 3-26-90 series.
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.
