Description

[0002] Large -scale bearing plays the key support role in various heavy -duty machinery and equipment, and its main function is to bear radial and axial load and reduce rotation friction through rolling contact. Since it works under high load and high speed operation condition, the raceway of bearing must have high hardness and wear resistance to ensure the long life and high performance of bearing.
