Thin-walled deep groove ball bearings consist of inner ring, outer ring, steel balls, cage, grease and seals.
Thin-walled deep groove ball bearing types:
Open and sealed two structures. There are open bearings, bearings with dust covers, seals or snap rings. Open type means that the bearing does not have a sealed structure, and the sealed thin-walled deep groove ball is divided into dust-proof seal and oil-proof seal. The material of the dust-proof sealing cover is stamped steel plate, which only serves to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.
