Deep groove ball bearing

Deep groove ball bearing is the most common type of rolling bearing. The basic 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 material of the dust-proof seal cover is steel plate stamping, which can only prevent dust from entering the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the grease in the bearing from overflowing. The type code of single row deep groove ball bearing is 6, and the code of double row deep groove ball bearing is 4. Its structure is simple and easy to use. It is the most popular and widely used type of bearing.
