Bearing ring production steps

The most important part of the bearing is the bearing ring. The bearing ring of the imported bearing is very good, and the quality is also very good. Then how to produce the bearing bearing ring?

1. Forging: Forging, overheating, and internal cracking of carbides in the forging process will reduce the toughness and strength of the ferrule. Therefore, we must always strictly control the processing temperature, cycle heating and cooling conditions after forging (such as spray cooling), especially after the final winding of large-scale varieties of ferrules, the temperature above 700 °C, shall not be placed stacked.

2. Heat Treatment: Close monitoring of heat treatment equipment is an important part of the workshop.

Monitor the reliability of the equipment. Instruments, thermocouples and other important temperature control devices must be closely monitored to ensure that the measurement data is accurate and reliable; timely replacement of errors exceeding the standard is strictly prohibited.

3. Monitoring of the grinding process. Finished imported bearing rings are not allowed to have grinding burns and grinding cracks. In particular, there must be no burns on the mating surface of the inner ring. If the ferrule is pickled, it shall be completely examined and the burned product shall be removed. Severely burned non-returnable or unqualified shall be discarded, and the ring that grinds the burn shall not be allowed to enter the assembly process.

4. Mark management: Before the steel is put into storage, it must be strictly managed before the ring is ground. The two different materials and products GCr15 and GCr15SiMn are strictly distinguished.
