32218Tapered roller bearings

32218Tapered roller bearings  have a conical inner ring and an outer ring raceway, and the tapered roller is arranged between the two. The projected lines of all conical surfaces meet at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing combined (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact Angle α. The larger the alpha Angle, the higher the axial load capacity. The Angle size is expressed by calculating coefficient e. The greater the e value, the greater the contact Angle, and the greater the applicability of the bearing to bear the axial load.
