S61AA3-SHH0816T is a single hub precision bearing housing made of aluminum with sulfuric acid anodized finish, designed for a 0.5000 inch bore and 1-15/16 inch overall length. It features two #6-32 tapped holes and two #26 clearance holes, with a ridge height of 0.687 inch and a dowel pin spot drill arrangement. The housing has two grooves in the bore diameter, consistent with units shorter than 3 inches. The part is dimensionally configured per Figure 1, with an overall length of 1-15/16 inches and a hub diameter of 1-3/4 inches.
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.
