Precision bearing housings made of aluminum with sulfuric acid anodized finish, designed for single hub mounting with a 0.5000 inch bore diameter and 0.750 inch overall length, featuring two #6-32 tapped holes and two #26 clearance holes. The housing includes two grooves in the bore diameter with a tolerance of +.0001 / -.0002 inches and is equipped with spot drills for dowel pinning. All dimensions conform to the inch-based design specifications for the S61AA3 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.
