These Spherical Roller Thrust Bearings are designed to accommodate heavy thrust loads. Due to raceways being inclined to the bearings axis, they can also accommodate radial loads up to a maximum of 55% of the thrust load and are suitable for taking high thrust loads at relatively high speed. Misalignment varies per series; figures are shown below.
Dimensions in accordance with ISO 104-2002

The bearings are fitted with asymmetrical barrel-shaped rollers. Dimensions con- form to ISO 104-2002. In general, lubrication of these bearings should be with oil except in certain exceptional cases. It is also essential that a minimum thrust load be present to avoid damage to the raceways by centrifugal forces (see formula below).
Fa min =1.5 cor /1000 [KN]
where: Fa min = minimum thrust load [KN] Cor = static capacity [KN]
