Tapered roller bearings have tapered inner and outer raceways with tapered rollers arranged in between. The projection lines on all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact Angle α. The larger the α Angle, the higher the axial load capacity. The Angle is represented by the calculated coefficient E. The larger the e value and the greater the contact Angle, the greater the applicability of bearing under axial load
