Spherical thrust roller bearings

In spherical roller thrust bearings the load is transmitted from one raceway to the other at an angle to the bearing axis. They are therefore suitable for the accommodation of radial loads in addition to simultaneously acting axial loads.  Another import- ant characteristic of spherical roller thrust bearings is their self-aligning capability.  This makes the bearings insensitive to shaft deflection and errors of alignment of the shaft relative to the housing.

Spherical roller bearings are of separable design; the shaft washer with roller and cage assembly, and the housing washer, can be mounted independently of each other.

FV spherical roller thrust bearings incorporate a large number ofasym- metrical rollers and have specially de- signed raceways with an optimum con- formity.They can therefore support very heavy axial loads and also permit relatively high speed operation.

FV spherical roller thrust bearings are produced in two designs depending on size and series.Bearings identified by the designation suffix E have a pressed steel window-type cage which forms a non- separable assembly with the rollers and shaft washer.All other bearings (no designation suffix, and those E-design bearings identified by suffix EM or EF) have a ma- chined cage of brass or steel which is guided by a sleeve held in the shaft washer.
