Spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.
Features and benefits
High load carrying capacity
The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.
Accommodate misalignment
spherical roller thrust bearings are self-aligning and can accommodate misalignment
Separable design
spherical roller thrust bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.
High speed capability
The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.
Long service life
The special roller profile reduces edge stresses at the roller/raceway contact.
Low friction
The optimized roller end / flange contact keeps frictional heat at low level, even at high speeds.
