Flange-mounted self-aligning needle roller bearing with a 12 mm bore, designed for radial load support and angular misalignment up to ±5°. The bearing features a drawn cup housing and a carbon steel housing with black oxide finish, operating within a temperature range of -30°C to +100°C. It requires a shaft with a nominal diameter of 12 mm, tolerance of 11.989 to 12.000 mm, and surface finish of 0.4 µm or finer. The bearing has an overall length of 39.6 mm, overall width of 28 mm, flange height of 2.3 mm, and mounting hole diameter of 5.5 mm. Maximum rotational speed is 20,000 rpm with a radial load capacity of 4000 N.
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.
