The A 7M 7-025 is a thrust bearing retainer component, designed for use with a complete bearing set that includes hardened S.A.E 1018 steel balls and a CR1075 steel washer. It is a molded nylon retainer rated for maximum operating temperatures of 250°F. The complete bearing set has a bore diameter of 1/4 inch, an outside diameter of 9/16 inch, and a total bearing thickness of 13/32 inch, with 8 balls sized to ±.0001 inch. The bearing is rated for a dynamic load of 131 lbf at 15 rpm and 69 lbf at 100 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.
