SKF single row tapered roller bearings (fig. 1) 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 (apex point A, fig. 2) 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 degree and 30 degree, is related to the calculation factor e (from the data table): the larger the value of e, the larger the contact angle.
