1. Material of bearing

The inner and outer rings of the bearing are turned by a lathe processing plant, and the accessories are strictly controlled to ensure that the bearing has a stable quality in the first production process. The bearing rings and steel balls are made of refined bearing steel; the cage is made of high-quality cold-rolled steel plate stamping or reinforced engineering plastics; the dust cover is made of SPCC, and the sealing ring is made of nitrile and oil-resistant rubber. The comparison of bearing steel model with ISO and other standards is as follows:
