How much do you know about tapered thrust bearings?

Tapered thrust bearings can form a very compact axial bearing configuration, which can withstand heavy axial loads, is not sensitive to impact loads, and has good rigidity. They are divided into unidirectional tapered thrust bearings and bidirectional tapered thrust bearings. The screw fixed bearing forms a specially designed unidirectional tapered roller thrust bearing, which is filled with rollers.
Unidirectional bearings can withstand unidirectional axial loads, and bidirectional bearings can withstand bidirectional axial loads.

The bidirectional bearing fits the middle ring with the shaft, but due to the use of clearance fit, it is necessary to use a shaft sleeve or other means to ensure the axial positioning of the middle ring. The main suitable cage is the copper alloy cut cage.

Structure and performance characteristics of tapered thrust bearings
Due to the fact that the rolling element in tapered thrust bearings is a conical roller, the rolling surface can form pure rolling with a limit speed higher than the thrust cylindrical roller bearing due to the fact that the rolling generatrix and the raceway generatrix of the washer intersect at a certain point on the axis of the bearing.
Tapered thrust roller bearings can withstand unidirectional axial loads.
The type code for tapered thrust bearings is 90000.
There are fewer models of thrust tapered roller bearings and most of them have non-standard shapes.

tapered thrust bearings application
Tapered thrust bearings are mainly used in heavy-duty machine tools, high-power marine gearboxes, oil drilling rigs, vertical motors, crane hooks, oil drilling rig rotating rings, two-way steel rolling mill journals, and other machinery.
