SKF Spherical roller bearing rings and rolling elements, to withstand repeated high contact pressure and at the same time accompanied by a sliding rolling contact. Retainer it? Side with the rings and rolling elements on both sides, or one side sliding contact side under tension and compression forces. Because of the above reasons, the bearing rings, rolling the material of the performance has the following basic requirements: 1, 2 rolling fatigue strength, high hardness, 3, 4 high wear resistance, dimensional stability, good 5, mechanical strength bearing performance requirements of the cage: 1, 2 high abrasion resistance, dimensional stability 3, the mechanical strength
