Rolling bearings in SKF bearings, the bearing rings and rolling elements repeatedly subject to high contact pressure, simultaneously accompanied by sliding of rolling contact. SKF bearing rings and rolling elements and cage side of sliding contact or on either side of a party, the other side is subjected to tension and compression forces. Therefore, because of the above reasons, our materials for SKF bearing rings and rolling elements, in performance to have the following basic requirements:
1, rolling fatigue strength
2, high hardness
3, high abrasion resistance
4, good dimensional stability
5, high mechanical strength
SKF bearing cages performance requirements:
1, high abrasion resistance
2, good dimensional stability
3, high mechanical strength
