Taper Roller Bearings
Taper housings are horizontally split and have two or four attachment bolt holes in the base as standard.
Taper bearing have tapered inner and outer ring raceways between which tapered rollers are arranged.
The projection lines of all the tapered surfaces meet at a common point on the axis. Taper roller design makes them particularly suitable for the accommodation of combined (radial and axial) loads.
The axial load carrying capacity of the bearing is largely determined by the contact angle. The larger the angle, the higher the axial load carrying capacity. An indication of the angle size is given by the calculation factor e the larger the value of e, the larger the contact angle and the greater the suitability of the taper bearing for carrying axial loads.
Taper bearing have the logarithmic contact profile that provides for optimum stress distribution over the roller/raceway contacts. The special design of the sliding surfaces of the guide flange and large roller ends considerably promotes lubricant film formation in the roller end/flange contacts.
The resulting benefits include increased operational reliability and reduced sensitivity to misalignment.
