The A 7Z58MBFM008L is a flange-mounted ball bearing with an 8 mm bore, designed for low-friction rotation in mechanical systems. It features double shields, a high chromium alloy steel bearing, and a carbon steel flange with black oxide finish. The bearing operates between -34°C and +121°C, supports a maximum radial load of 544 N dynamic and 275 N static, and can reach speeds up to 40,000 rpm. It self-aligns up to ±5° and has a flange diameter of 22.2 mm, an overall height of 16.5 mm, and a mounting hole diameter of 5.6 mm. The component meets ABEC 3 precision standards.
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.
