What is Deep Groove Ball Bearing?
Deep groove ball bearings are very typical in rolling bearings. It is also very suitable for high speed operation or very high speed operation. Because of its small friction coefficient, high speed limit and simple structure, it has a wide range of applications in precision instruments, low noise motors, automobiles, general machinery and other industries. The inner and outer ring raceways of deep groove ball bearings are arc-shaped deep grooves that can withstand radial loads, bidirectional axial loads and combined loads.
The main structure of the deep groove ball is divided into a basic type with a dust cover and a sealing ring. Deep groove ball bearings with dust cover, there is a radial gap between the dust cover and the inner ring, and there is no need to fill in the lubricant during use. Deep groove ball bearings with seals or steel frame rubber seals have two types in contact and non-contact.
The self-aligning ability of deep groove ball bearings is limited, so it is also necessary to have good concentricity when the bearings are installed. If the concentricity is not good, it will directly affect the stability of the operation and increase the stress of the bearings. Therefore, the deep groove ball bearings can only allow a small deflection angle, which is also dependent on the size of the load.
Generally speaking, the accuracy of deep groove ball bearings can meet most of the equipment performance requirements. When there are special requirements for vibration and noise of bearing operation, the corresponding grade of bearings should be selected. At high speeds, deep groove ball bearings are subject to frictional increases and temperature rises when subjected to loads. In order to ensure that the bearing does not slip, the minimum radial load needs to be applied.
