DPI - Bearings

Performance in Motion

DPI® Tapered Roller Bearings have tapered surfaces whose apexes conferge at a common point on the bearing axis. This type of bearing is suitable for applications involving heavy or impact loading.

Application: Industrial

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 α (fig 1); the larger α, the higher the axial load carrying capacity (fig 2). 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).

Single Row Tapered roller bearings are able to carry axial and radial load in one direction simultaneously. Double row tapered roller bearings can accommodate very high radial and axial loads in both directions.

The standard cages used are pressed steel cages.
