Thrust ball bearing 51106 51107 51108 Bearing impact resistance bearing ball bearing

According to the force situation, it is divided into unidirectional thrust ball bearings and bidirectional thrust ball bearings. Unidirectional thrust ball bearings can withstand unidirectional axial loads. Bidirectional thrust ball bearings can withstand bidirectional axial loads, where the shaft ring fits with the shaft. The bearing with a spherical installation surface of the seat ring has centering performance, which can reduce the impact of installation errors. The thrust ball bearing cannot withstand radial loads and has a lower limit speed.

Unidirectional thrust ball bearings can only withstand loads in one direction, and if they are subjected to loads in both directions, they must be selected as bidirectional thrust ball bearings. The thrust ball bearing must apply a minimum load or preload. When the axis is vertical, the weight of the axis usually exceeds the minimum load. At this point, due to the influence of the axial external load in the opposite direction, the load acting on it may decrease.

When the thrust ball bearing operates at high speed, the contact angle between the steel ball and the radial plane of the raceway is affected by centrifugal force, which causes the steel ball to slide relative to the raceway. The adhesive wear caused by this sliding can damage the bearings. To prevent such damage, it is necessary to ensure the minimum load borne by the thrust ball shaft.
