SKF needle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers. The very small diameter deviation of the rollers within one assembly enables these bearings to accommodate heavy axial loads and shock loads.

SKF cylindrical roller thrust bearings are designed to accommodate heavy axial loads and shock loads. They must not be subjected to any radial load.
The ends of the rollers are relieved slightly to modify the line contact between the raceways and rollers. This prevents stress peaks at the roller ends to extend bearing service life.

CARB toroidal roller bearings combine the self-aligning capability of spherical roller bearings with the axial displacement ability of cylindrical roller bearings. CARB bearings can also have the compact cross section and high load carrying capacity normally associated with needle roller bearings.

Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
Single row tapered roller bearings
The SKF standard assortment of single row tapered roller bearings comprises popular sizes of metric single row tapered roller bearings in accordance with ISO 355:2007 and inch bearings in accordance with ANSI/ABMA Standard 19.2-2013.

Double row tapered roller bearings
Double row tapered roller bearings can carry heavy loads and are stiff. They are suitable for the accommodation of combined (radial and axial) loads and can locate a shaft axially in both directions with a given axial clearance or a given preload. Their main use is in gearboxes, hoisting equipment, rolling mills and machines used in the mining industry, e.g. tunnelling machines.

Four-row tapered roller bearings
Four-row tapered roller bearings are used successfully worldwide for rolling mill bearing arrangements where rolling speeds are slow to moderate. Because of their design they are able to take up those axial loads which occur in such applications in addition to radial loads and generally no separate thrust bearings are required in such arrangements.
