When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The deep groove ball bearing has a small friction coefficient and the limit rotation speed is also high. ProductSiteLaunchDate : 2024-04-02T14:55:00.028Z Size : One Size UnitCount : 1
