Spherical roller thrust bearing

With specially designed raceways and rollers, HKT Spherical Roller Thrust Bearings are capable of achieving a higher thrust capacity with lower friction and better performance in self-alignment. 

In particular, contract manufacturing is accepted upon written requests enable you to build non-standard bearings. 

HKT spherical roller thrust bearings, typically, are able to accommodate heavy axial loads in one direction and heavy radial loads at relatively high speeds. From the perspective of the internal design, rollers have a shape conformity with raceways to distribute loads along the roller length. Meanwhile, spherical rollers are arranged in a steep angular position, which permits to accommodate high thrust loads and support moderate radial loads. In other words, the loads are able to distribute between the raceways at an angle to the bearing axis. 

The other hand, raceways of HKT spherical roller thrust bearings are spherical with the center of the radius located on the bearing axis. The design provides self- alignment capability to the bearing. Typically, spherical roller thrust bearings are self-aligning and insensitive to static misalignment of the shaft relative to the housing.

Depended on unique features, this type of bearings is better serving under conditions featured with heavy loads and difficulty in establishing or maintaining housing alignment, or shaft deflection. For instance: 

- Blowout preventers

- Classifiers

- Extruders

- Gearboxes

- Metal mill work/back-up rolls

- Pre-heater fans

- Pumps

- Screw conveyors
