The load-bearing capacity of a bearing depends on the raceway angle of the outer ring
2026-09-17
Tapered roller bearings mainly support combined radial and axial loads with a predominance of radial loads. The load-bearing capacity of a bearing depends on the angle of the outer ring raceway: the larger the angle, the higher the load-bearing capacity. Tapered roller bearings have tapered inner and outer ring raceways with tapered rollers between them. The projection lines of all conical surfaces converge at one point on the bearing axis.
This design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) loads. The axial load carrying capacity of a bearing is largely determined by the contact angle α; The larger the angle α, the higher the axial load capacity. The magnitude of the angle is expressed by the calculated coefficient e; The larger the e value, the larger the contact angle and the higher the bearing's suitability for supporting axial loads.
Tapered roller bearings are typically split, meaning the tapered inner assembly, consisting of an inner ring with rollers and cage, can be mounted separately from the tapered outer ring (outer ring).
Tapered roller bearings are widely used in automobile manufacturing, rolling mills, mining, metallurgy, plastic machinery manufacturing and other industries.
