Tapered roller bearings are produced in many designs and sizes to match their many uses. They can be grouped as follows

–	single row tapered roller bearings
–	paired single row tapered roller bearings
–	double row tapered roller bearings
–	four-row tapered roller bearings

Design features
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the contact angle

the larger α, the higher the axial load carrying capacity

An indication of the angle size is given by the calculation factor e; the larger the value of e, the larger the contact angle and the greater the suitability of the bearing for carrying axial loads.

Tapered roller bearings are generally separable, i.e. the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring).
