Tapered Roller Bearings

Tapered roller bearings have tapered inner and outer ring raceways as well as 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 a true rolling action and therefore low frictional moments during operation The axial load carrying capacity of tapered roller bearings increases with increasing contact angle ± The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e the larger the value of e, the larger the contact angle.
