|The bidirectional thrust ball bearing comprises a shaft ring, two seat rings and two ball - cage assemblies. Bearing is separate type, each part can be installed independently. Two-way bearings use the same ring, seat and ball - cage assembly as unidirectional bearings.|
Bi-directional thrust ball bearings can withstand bi-directional axial loads and are positioned as bi-directional axial loads, but must not withstand any radial loads.
In order to make the bearing run well, thrust ball bearings, like all ball bearings and roller bearings, must bear a certain minimum load, especially at high speed or high acceleration, or in the direction of load change quickly. Under these conditions, the inertia forces of the ball and cage and friction within the lubricant will adversely affect the rolling of the bearing, and damaging sliding motion may occur between the ball and the raceway. A larger minimum load may be required when starting at low temperatures or when lubricant viscosity is high. The weight of bearing support, coupled with external forces, especially in the case of vertical axis, usually exceeds the required minimum load, it must be pretightened, such as the use of springs.
