Deep groove ball bearing is suitable for high speed or even very high speed operation, and it is very durable, without frequent maintenance. This kind of bearing has the advantages of small friction coefficient, high limit speed, various size range and forms, and is widely used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries. It can bear radial load and axial load.
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 can be divided into sealed and open type. Open type means that the bearing does not have a sealed structure. Sealed deep groove ball can be divided into dust-proof seal and oil-proof seal. The material of dust seal cover is steel plate stamping, which can simply prevent dust from entering bearing raceway. The oil proof type is the 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. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.
