The spherical roller thrust bearing is featured by the extremely big axial load carrying capacity and meanwhile they can also carry certain radial load. The roller is in spherical shape, and the spherical raceway surface of housing washer is self-aligned. Oil lubrication is commonly used while it is working. Applications of these bearings can be found in hydroelectric generators, vertical motors, propeller axle of vessels, tower cranes and squeezing presses.

WBJF mainly provides the spherical roller thrust bearing in YA3 structure. It is characterized by cancellation of bushing, thus slipping of loose bushing is avoided and performance of bearings is improved.
