Use Of Tapered Roller Bearings

- Aug 17, 2017 -

Tapered roller bearings are mainly subjected to radial and axial joint loads. Bearing capacity depends on the raceway angle of the outer ring, the greater the angle The greater the carrying capacity. The bearings are separated type bearings and are divided into single row, double row and four row tapered roller bearings According to the number of rolling bodies in the bearing. Single row tapered roller bearing clearance needs to be adjusted by the user at installation; Double row and four row tapered roller bearing clearance has been given in the product at the time of the factory according to user requirements, do not need user adjustment. 


Tapered roller bearings have conical inner ring and outer ring raceway, and tapered rollers are arranged between them. All the projection lines on the cone surface are clustered at the same point in the bearing axis. This design makes tapered roller bearings particularly suitable for composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α, and the higher the angle of the α, the greater the axial load capacity. The angle size is expressed by the calculated coefficient E, the larger the E value, the greater the contact angle, the greater the suitability of the bearing to withstand axial load.


Tapered roller bearings are usually separate, that is, the cone inner ring component consisting of the inner ring of the roller and cage assembly can be installed separately from the cone Outer Ring (outer ring).


Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.
