Ball bearing is a rolling ball ball equipment, including steel ring and the outer steel ring in the middle, able to withstand greater loads. Also known as ball bearings.
Ball bearings are mainly constituted by the four basic components: the ball (ball), the inner ring (inner ring), the outer ring (outer ring) and retainer (cage or retainer). Ball bearings for general industrial use to meet the standard AISI 52100, ball and ring usually made of high chromium steel, Rockwell hardness (Rockwell C-scale hardness) between about 61-65. The retainer ring hardness compared with the low ball, the material of metal (such as: carbon steel, aluminum) or nonmetallic (such as: Teflon, PTEF, polymer materials). Ball bearings (ball bearing) than journal bearings (journal bearing) of the rotating friction is small, so the same speed, the friction will be relatively low temperature.
