Tapered inner and outer ring raceways with tapered rollers. Projection lines meet at common point on bearing axis. Suitable for combined radial and axial loads.

EntrustBearing produces taper roller bearings in many designs and sizes to match their many uses.

• Single row taper roller bearings
• Double-row taper roller bearings
• Four-row 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.

The axial load carrying capacity of the bearings is largely determined by the contact angle α. 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.

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