Deep groove ball bearings are composed of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings, single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a sealed structure. The sealed deep groove ball is divided into dust-proof and oil-proof. seal. The material of the dust-proof seal cover is stamped with 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.

Deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retaining structures. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open structures. Open means that the bearing does not have a sealed structure. The sealed deep groove ball is divided into dust seal and oil seal. The dust-proof sealing cover is made of steel plate stamping, which only plays a simple role in preventing dust from entering the bearing raceway. The oil proof type is a contact oil seal, which can effectively prevent the grease overflow in the bearing.
