Thrust ball bearings

Feature

This type of bearings is separable and the contact angle is 90 degree.So the bearings can only carry axial load. While the bearings runing, the balls are extruded to the outside of raceway by centrifugal effect and easy to be scraped. So this typy of bearing can not be used under the high speeds condition.

The single direction bearings of them can only carry axial load in one direction, while the double can carry alternating axial load in either direction.

And the trust ball bearings with spherical outer ring have self-aligning functions.

In double-direction angular contact thrust ball bearings, the contact angle is 60 degree. they can take axial load forn double-directions and the unit load form axial and radial drection. Furthermore, the bearings have a capacity of axial space limiting,and also do a little to the radial space limiting.

CAGES

Pressed steel and machined brass cages are commonly used.

APPLICATIONS

The thrust ball bearings are used in lathe centers, automobile clutches, reducers and so on.

Thrust Roller Bearings

Cylindrical roller thrust bearing

This type of bearing is separable and can carry heavy axial loads. They are single directions bearings and can only accommodate axial load in one direction.They can't limit the dispalcement in radial. They are stiff and insensitive to shock loads, and they require little space. Their main use is in applications where the load carrying capacity of thrust ball bearing is inadequate and the speeds requirement is low.

The leaning of the shaft is forbidden when the beaings are used.

Cage

Machine brass caged are gennerally used.

APPLICATIONS

The bearings are suitable for oil drilling machine, metal producing equpiment, etc.
