Production Steps Of Bearing Rings

1. Forging: If the forging process is over-burned, overheated or internally cracked into network carbides, the toughness and strength of the bearing rings will be reduced. Therefore, the processing temperature, circulating heating and post-forging heat dissipation conditions must be strictly controlled. Especially after forging larger bearing rings, when the temperature is higher than 700 °C, the product should not be stacked.

2 Heat treatment: Close monitoring of heat treatment equipment is an important task in the workshop. Monitor the reliability of the equipment. Important temperature control devices, such as instruments and thermocouples, must be closely monitored to ensure accurate and reliable measurement data; it is strictly forbidden to replace too many errors in time.

3 Monitor the grinding process. The finished bearing ring is not allowed to wear and grind, especially on the mating surface of the inner ring taper. If the bearing ring is pickled, thoroughly check and remove the charred product. If the burn is not repaired or the repair is unqualified, it should be scrapped. Unqualified grinding rings are not allowed to enter the assembly process.

4 Label management. Each process must be strictly managed before the steel is put into storage and before the casing is ground, and the materials and products must be strictly distinguished.
