Deep groove ball bearing

Deep groove ball bearing is the most common type of rolling bearing. The basic deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of retaining frames. There are two types of deep groove ball bearings: single-row and double-row. The structure of deep groove ball is divided into seal and open-type. The open-type refers to the bearing without seal structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof seal. Dust-proof sealing cover material is stamped by steel plate, which can only prevent dust from entering bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent grease spillover in the bearing.
