Deep groove ball bearing

Deep groove ball bearings are the most common type of rolling bearings. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set 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 types. Open type refers to bearings without a sealed structure, while sealed deep groove balls are divided into dust-proof and oil proof seals. The dustproof sealing cover material is stamped steel plate, which only plays a simple role in preventing dust from entering the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the lubricating grease inside the bearing from overflowing. The type code for single row deep groove ball bearings is 6, and the code for double row deep groove ball bearings is 4. Its structure is simple and easy to use, making it the most commonly produced and widely used type of bearing
