Spherical roller bearings are inherently self-aligning and are robust. Double row rollers enable the bearing to withstand heavy loads. Spherical roller bearings have been improved over the years in a wide range of sizes, including individual ISO size families, as well as special designs such as bearings for shakers and similar applications.

Spherical roller bearings have two rows of rollers with a shared spherical raceway on the outer ring and two inner raceways that are tilted at an Angle relative to the bearing shaft. This gives the bearing attractive design features that cannot be replaced in many demanding applications. These bearings have self-aligning function and are not sensitive to the deformation or distortion of the shaft relative to the bearing seat. Spherical roller bearings are in a position in the design, which can bear not only high radial load, but also high axial load in two directions.
