Tapered Roller Bearings

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

These are described in four separate sections under the appropriate headings.

SKF also manufactures sealed, greased and pre-adjusted units based on tapered roller bearings, such as

  • hub bearing units for passenger cars (fig)
  • hub bearing units for trucks (fig), and
  • tapered bearing units (fig) for railbound vehicles.

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 a (fig); the larger a, the higher the axial load carrying capacity (fig). 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).

SKF tapered roller bearings have the logarithmic contact profile that provides optimum stress distribution over the roller/raceway contacts. The special design of the sliding surfaces of the guide flange and large roller ends considerably promote lubricant film formation in the roller end/flange contacts. The resulting benefits include increased operational reliability and reduced sensitivity to misalignment.
