Spherical Thrust Roller Bearings
Spherical thrust roller bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously working 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.
Spherical Thrust Roller Bearings
Spherical thrust roller bearings have asymmetrically sphered rollers. These bearings have one shaft washer raceway and one housing washer raceway and the load is transmitted at an angle to the bearing axis. The rollers conform closely to the inner and outer raceways giving the bearings high load carrying capacity and are internally self-aligning.

Types of spherical thrust roller bearings
External dimensions of spherical thrust roller bearings are standardised by ISO in the standard ISO 104:2015. Some common series of spherical roller bearings are:
- 292
- 293
- 294
Features of spherical thrust roller bearings
- 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 thrust roller bearings are self-aligning and can accommodate misalignment. - Separable design
Spherical thrust roller bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer, 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 unique roller profile reduces edge stresses at the roller/raceway contact. - Low friction
The optimized roller end/flange contact keeps frictional heat low, even at high speeds.
Applications of spherical thrust roller bearings
Spherical thrust roller bearings are used in industrial applications, where there are heavy axial loads, moderate speeds, and possibly misalignment. Some common application areas are:
- Gearboxes
- Pulp and paper processing equipment (notably refiners)
- Marine propulsion and offshore drilling
- Cranes and swing bridges
- Water turbines
- Extruders for injection molding
