Deep groove ball bearings are suitable for high or even extremely high speed operation, and are very durable and need not be maintained regularly. This kind of bearing has small friction coefficient, high limit speed, varied size range and form. It is widely used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used type of bearing in machinery industry. It is mainly subjected to radial load and can also bear a certain amount of axial load.

Essential information
Deep groove ball bearings are the most common type of rolling bearings. This type of 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 two types: sealed and open. The open type refers to the bearing without sealing structure. The sealed deep groove ball can be divided into dust-proof seal and oil-proof seal. The dust-proof sealing cover material is made of steel sheet and only prevents dust from entering the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the grease from overflow in the bearing. The single row deep groove ball bearing type code is 6, the double row deep groove ball bearing code is 4. Its structure is simple and easy to use. It is the most widely used and most widely used kind of bearings.
