Tapered Roller Bearings

Item No.: 2
Manufacturing dimensions and structural deformation
Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the angle is related to the calculation factor e the larger the value of e, the larger the contact angle. A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

Single row tapered roller bearings

The standard assortment of single row tapered roller bearings comprises popular sizes of metric single row tapered roller bearings.

Double row tapered roller bearings

Double row tapered roller bearings can carry heavy loads and are stiff. They are suitable for the accommodation of combined (radial and axial) loads and can locate a shaft axially in both directions with a given axial clearance or a given preload. Their main use is in gearboxes, hoisting, rolling mills and machines used in the mining industry, e.g. tunnelling machines.
