Spherical Roller Thrust Bearings are the same with spherical roller bearing, both of them are all self-aligning design, the raceway surface of the seat is a sphere which centered on a point and be coincident with the center axis of the bearing. and also the rollers of Spherical Roller Thrust Bearings are spherical, Therefore, it has self-aligning function, Less sensitive to concentricity and shaft deflection.

Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has lower friction factor, higher speed and has self-aligning performance.

The roller of the 29000 type spherical roller thrust bearing is an asymmetrical spherical roller, which can reduce the relative sliding of the roller and the raceway during operation, and the roller has a long length , a large diameter, a large number of rollers, a high load capacity , and is usually oil lubricated . Individual low speed conditions can be lubricated with grease. When designing and selecting, it should be preferred;

Advantages of Spherical Roller Thrust Bearings

• Higher performance bearingarrangements: more than double the rating life due to basic dynamic load ratings that are up to 30 % higher than before , higher static load safety factor due to basic static load ratings nearly 10 % higher, reduced wear due to improved surface quality and optimum lubricant film formation, higher speed capability due to reduced friction and operating temperature as well as special cage designs.

This is all made possible by longer rolling elements, optimised contact geometry and bearing kinematics, improved surfaces of the rolling contact partners for an optimised lubricant film, cages with better guidance of rollers and lubricant as well as closer dimensional and running tolerances.
