Features:
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.Depending upon the contact angle, tapered roller bearings are divided into three types; normal angle, medium angle, and steep angle.
