Single row tapered roller bearings are designed to carry combined loads, i.e. radial and axial loads acting simultaneously. The projection lines of the raceways intersect at a common point on the bearing axis to provide true rolling action and therefore have low frictional torque during operation. The axial load carrying capacity of a tapered roller bearing increases with increasing contact angle ±. The size of the contact angle, usually between 10 and 30, is related to the calculated coefficient e: the higher the value of e, the higher the contact angle.
