Double-row spherical roller bearings have spherical raceways in the outer rings of two rows of rollers. They can handle large radial loads and are able to bear axial load in any direction.

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.

Full complement cylindrical roller bearing is a kind of cylindrical roller bearing designed without cages. In this design, the number of rollers are the biggest in all the bearings types.
