Material Selection

In terms of material procurement, our company has developed a series of procurement control procedures for raw and auxiliary materials and outsourcing, and there are strict control procedures from the selection of qualified suppliers to the acceptance of raw and auxiliary materials.

All of our products use the best GCr15 steel. GCr15 steel is a kind of high carbon chromium bearing steel with low alloy content, good performance and wide application range. After quenching and tempering, the hardness is high, uniform, good wear resistance and high contact fatigue performance.

2、Heat Treatment

Our company owns two automatic RJXQ-90 quenching and tempering automatic lines, one automatic production line of GX300 roller bottom quenching and tempering. The quenching consistency of the furnace is good, the hardness is uniform, the gas protection is oxygen-free and the deformation is small. It can effectively control the deformation, reduce the grinding allowance and improve the bearing life.
