Deep groove ball bearings have a high limit speed

Deep groove ball bearings mainly bear radial loads, and can also bear radial loads and axial loads at the same time. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The friction coefficient of the deep groove ball bearing is small, and the limit speed is also high.
Deep groove ball bearings are the most commonly used rolling bearings. It has a simple structure and is convenient to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing, and can bear combined radial and axial loads. When the speed is high and thrust ball bearings are not suitable, they can also be used to bear pure axial loads. Compared with other types of bearings with the same specification and size as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. However, it is not resistant to impact and is not suitable for heavy loads.
After the deep groove ball bearing is installed on the shaft, within the range of the axial clearance of the bearing, it can limit the axial displacement of the shaft or the housing in two directions, so it can be positioned axially in both directions. In addition, this type of bearing also has a certain self-aligning ability. When it is tilted 2'~10' relative to the housing hole, it can still work normally, but it will have a certain impact on the life of the bearing.
The structure of deep groove ball bearing is simple, and it is easy to achieve higher manufacturing precision compared with other types, so it is easy to be mass-produced in series, and the manufacturing cost is also low, so it is widely used. In addition to the basic type, deep groove ball bearings also have various variant structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seal rings, deep groove ball bearings with stop grooves, Large load capacity deep groove ball bearings with ball notches, double row deep groove ball bearings.
