Deep groove ball bearing

Deep groove ball bearing is a 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 dust-proof sealing cover is 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 overflow of lubricating grease 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 a kind of bearing with universal production and wide application. Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.
Deep groove ball bearing has simple structure and is easy to achieve high manufacturing accuracy compared with other types, so it is convenient for series mass production, low manufacturing cost and widespread use. In addition to the basic type, the deep groove ball bearing also has various variant structures, such as: deep groove ball bearing with dust cover, deep groove ball bearing with rubber sealing ring, deep groove ball bearing with stop groove, deep groove ball bearing with large load capacity with ball notch, and double row deep groove ball bearing.
