Product Description


Ball bearing is mainly composed of four basic elements: ball, inner ring, outer ring and cage or retainer. General industrial
ball bearings meet the standard of AISI 52100. Ball bearings and rings are usually made of high chromium steel, with Rockwell
C- scale hardness between 61 and 65. However, the hardness of the retainer is lower than that of the ball and ring, and its materials
are metal (such as medium carbon steel and aluminum alloy) or nonmetal (such as PTEF and polymer materials). Ball
bearing has smaller rotational friction resistance than journal bearing, so the temperature caused by friction will be lower at
the same speed.
