Introduction:
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 α 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.

Bearing feature:
1.Low friction
2.Long service life
3.Enhanced operational reliability
4.Consistency of roller proiles and sizes
5.Rigid bearing application
6.Running-in period with reduced temperature peaks
7.Separable and interchangeable
