Tapered roller bearing

single row tapered roller bearings 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 (from the product catalogue): the larger the value of e, the larger the contact angle.

Advantage
· Impact resistance
· High temperature resistance
· Good oil resistance

Paired use

Under certain special application conditions, we can combine two single row tapered roller bearings together (as shown in the DF and DB combination in the above figure 1 an 2). This pairing method can withstand larger radial and axial loads, and can also withstand axial loads in both directions.

In addition, we also have double row tapered roller bearings with integrated inner or outer rings, as shown in the following figure 3 and 4
