Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy 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 bearings and can bear radial and axial combined loads. When the speed is high and thrust ball bearings are not suitable, they can also be used to bear pure axial loads. Compared to other types of bearings of the same size as deep groove ball bearings, these bearings have a small coefficient of friction and a high limiting speed. However, it is not resistant to impact and is not suitable for heavy loads.
Deep groove ball bearings mounted on the shaft can limit the axial displacement in both directions of the shaft or housing within the axial clearance range of the bearing, so they can be positioned axially in both directions. In addition, this type of bearing also has a certain aligning ability, when tilted 2′~10′ relative to the housing bore, it can still work normally, but it has a certain impact on bearing life.
