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 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. The type code of single row deep groove ball bearing is 6, and the code of double row deep groove ball bearing is 4. The utility model has the advantages of simple structure and convenient use. It is the most widely used bearing in production.
