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.

Spherical roller thrust bearings
features :

This type of bearings is separable. The spherically formed outer ring raceway can make selfalignment. There fore ,if there is deflection of the shaft,it is automatically corrected.There is an angle between the working line of load and the center line of shaft.Then bearings can take not only greatly radial load but also some axial loads in either direction. They have excellentload-carrying capacity and are suitable for use where there are heavy or impact loads, such as waterpower, upright style electromotor ect.

Before using they have to be preloaded.
