Spherical thrust roller bearings is a kind of thrust rolling bearing. They allow low friction rotation and angular deviation and are designed to bear radial load and one-way axial load.

Toroidal roller bearings are kind of new single-row radial bearing. It has crowned symmetrical rollers and circular ring raceways.The rollers of the toroidal bearings are self-guiding, that’s to say they adjust the position in which the loads are averagely distributed over the length of the rollers no matter the inner ring is axial displaced or not. The raceways of the inner rings and outer rings are concave and arranged symmetrically about the center of the bearings.

It can bear simultaneously radial load and single row axial load. According to contact angle, it is classified into 3 types: small, medial and big cone angle.
