Flange-mounted ball bearing with a 1/4 inch bore, designed for low-friction rotary support in applications requiring self-alignment up to ±5°. The bearing features double shields, a high chromium alloy steel ball race, and a carbon steel flange with black oxide finish. It operates between -30°F and +250°F, supports a static radial load of 61 lbf and a dynamic radial load of 122 lbf, and has a maximum speed of 40,000 rpm. The overall dimensions include a flange outer diameter of 1.78 inches and a mounting hole diameter of 0.22 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.
