The Main Purpose Of Tapered Roller Bearings

Tapered roller bearings are mainly subjected to radial and axial combined loads. The bearing load carrying capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the load carrying capacity. This type of bearing is a separable type bearing, which is divided into single, double and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. Single row tapered roller bearing clearance needs to be adjusted by the user during installation; Double and four row tapered roller bearing clearances are given at the factory according to user requirements and do not need to be adjusted by the user.
Tapered roller bearings have tapered inner and outer ring raceways, with tapered rollers arranged in between. The projection lines of all tapered surfaces meet at the same point along the bearing axis. This design makes tapered roller bearings particularly suitable for compound (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; The larger the α angle, the higher the axial load capacity. The angular magnitude is expressed by the calculated coefficient e; The higher the e-value and the larger the contact angle, the greater the suitability of the bearing for axial loads.
