Double direction thrust ball bearings
Introduction of Double direction thrust ball bearings
The Double direction thrust ball bearings includes a shaft collar, two races and two steel ball-cage assemblies. The bearings are separable and each part can be mounted separately. Both the Double direction thrust ball bearings and the Single direction thrust ball bearings use the same shaft collar, race and ball-cage assembly. Double direction thrust ball bearings can withstand Double direction axial loads and act as two-way axial positioning, but must not withstand any radial loads
