Screw holes are made at the position where the inner ring extends beyond the outer ring, and set screws are used for reinforcement.

[0003] Based on the above, the bearings currently in use adopt the installation method of set screw locking. The force is applied through a point, which results in large force. After long-term operation or when replacing the bearing, the shaft is prone to wear, making it inconvenient to replace and use. Moreover, the stability effect is generally poor. After the shaft wears out, the set screw will loosen, resulting in a lack of stable connection. Utility Model Content
