Flange-mounted self-aligning needle roller bearings with an 8 mm bore, designed for radial load support and alignment up to ±5°. The bearing features a drawn cup needle roller design and a carbon steel housing with a black oxide finish, operating within a temperature range of -30°C to +100°C. The shaft must have a hardness of HRC 58 to 64 and a surface finish of 0.4 µm or finer. The bearing has an overall length of 45 mm, flange height of 19.5 mm, mounting hole diameter of 5.5 mm, and a maximum radial load rating of 2550 N at a maximum speed of 28,000 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.
