Taper Roller Bearings

Taper 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 taper roller bearings particularly suitable for the accommodation of combined (radial and axial) loads.

Taper 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).Taper roller bearings are produced by in many designs and sizes to match their many uses. These can be grouped as follows

- single row taper roller bearings

- paired single row taper roller bearings 

- double row taper roller bearings

- four-row taper roller bearings
