After the Deep Groove Ball Bearing is installed on the shaft, it can limit the axial displacement of the shaft or the housing in both directions within the axial clearance of the bearing, so it can be axially positioned in both directions. When Deep Groove Ball Bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. Under high-speed operating conditions with large axial loads, Deep Groove Ball Bearings are more superior than thrust ball bearings. In addition, this type of bearing also has a certain degree of aligning ability. When it is inclined 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.
