General information of deep groove ball bearing
Deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages. There are two types of deep groove ball bearings: single row and double row. Deep groove ball structure is also divided into seal and open structure. The open type means that the bearing has no sealing structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof seal. The dust-proof seal cover is made of steel plate, which only serves as a simple way to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent grease overflow in the bearing.
Working principle of deep groove ball bearing
It mainly bears radial load, and also can bear axial load and radial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high.
Characteristics of deep groove ball bearing
Deep groove ball bearings are suitable for high speed operation, and they are very durable without frequent maintenance. This kind of bearing has the characteristics of small friction coefficient, high limit speed, various sizes and forms; they are used in household appliances, agricultural machinery, motor, power tools, textile machinery, printing machinery, automotive industry, washing machines motors, dental drills, bicycles, tricycles, motorcycles, etc. It is one of the most widely used bearing in mechanical industry. It mainly bears radial load, and also can bear a certain amount of axial load.
