The rings and rolling elements of rolling bearings are repeatedly subjected to high contact pressures, and at the same time they carry out rolling contact with sliding. What about the retainer? One side is in sliding contact with the two sides of the ring and the rolling element, or one side, and the other side bears the tensile force and the compressive force.

    Because of the above reasons, there are the following basic requirements for bearing rings, rolling element materials and performance,TIC-TECHS Bearing shares the following points :

    1. High rolling fatigue strength

    2. High hardness

    3. High wear resistance

    4. Good dimensional stability

    5. High mechanical strength

    Performance requirements of bearing cage:

    1. High wear resistance

    2. Good dimensional stability

    3. High mechanical strength
