Deep groove ball bearings, also known as DGBB bearing, are the typical rolling bearings which have the most widely application.
Basic deep groove ball bearings of different sizes are made up of one inner ring, one outer ring, one cage and a group of balls. It can bear both radial and axial load capacity. Therefore, it can also be divided into axial deep groove ball bearing and radial deep groove ball bearing.

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.

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.
