The steps of bearing ring production

The most important part of the bearing is the bearing ring. The collar of the imported bearing is very good and the quality is very good. So how to produce the collar of the imported bearing?

1. forging: if excessive burning, overheating and internal cracking into mesh carbide are produced during forging, the toughness and strength of the collar will be reduced. Therefore, we must always strictly control the processing temperature, cycle heating and cooling conditions after forging, such as spray cooling. Especially after the final forging of a large variety of rings, the temperature should not be piled up if the temperature is above 700 degrees.

2. heat treatment: close monitoring of heat treatment equipment is an important work in the workshop.

Monitor the reliability of the equipment. The important temperature control instruments such as instruments and thermocouples shall be closely monitored to ensure the accuracy and reliability of measurement data; If the error exceeds the standard, it is required to replace it in time, and it is strictly forbidden to operate with diseases.

3. monitoring of grinding process. Grinding burn and grinding crack are not allowed on the bearing collar at the inlet of finished product, especially on the mating surface of cone modification. If the ferrule is pickled, it shall be inspected completely, and the burned products shall be removed. If the serious burn cannot be repaired or the unqualified repair is not qualified, it shall be scrapped. The ferrule with grinding burn shall not be allowed to enter the assembly process.

4. identification management. After the steel is put into storage and before the ring grinding, each process must be strictly managed, and two different materials and products, GCr15 and GCr15SiMn, must be strictly distinguished.
