A needle roller bearing is a bearing which uses small cylindrical rollers.The difference between a needle roller bearing and roller bearing is the ratio of diameter and length of their rollers, when the ratio of the diameter and the length of roller of a roller bearing is between the interval of 0.1 to 0.4, that roller bearing is called a needle roller bearing. They are used to reduce the friction of a rotating surface.
RLEM needle bearings material is Gcg15 chrome steel.bainite heat treatment , quality contraolled by ISO AND SGS standard. Rotation precision above P5 ,all bearing passing noise testing ,shaking testing .and other Physical properties testing. |
