Chrome Steel Deep Groove Ball Bearings High Precision 61909 2RSR 2Z
Description:
Deep groove ball bearing is used to accommodate the pure radia load, it also can accommodate combined load of radia and axial. When it only accommodate pure raidal load, the contact angle is 0, it will own the same character as angle contact bearing and accommodate larger axial load when it has larger radial chearance.Deep groove ball bearing's friction coefficient is very small and extreme speed also is very high, particularly at the condition of the big axial load runs with high speed. it will own larger superiority than thrust ball bearing.
