Product Description

Tapered roller bearings are separable bearings featuring tapered raceways on both inner and outer rings. The inner ring and a set of tapered rollers form an inner ring assembly enclosed by a cage-type retainer. The outer ring can be separated from the inner ring assembly, enabling universal interchangeability. Designed to accommodate combined loads—simultaneous radial and axial forces—these bearings deliver exceptional load capacity and operating speeds with low friction torque during operation. Widely employed in automotive front and rear wheels, machine tool spindles, construction machinery, large agricultural equipment, railway vehicle gear reducers, and speed reduction units.


Product Features

- Separable rings: Detachable and interchangeable components facilitate installation, disassembly, and maintenance.

- High load capacity and rigidity: Tapered roller bearings can withstand exceptionally high radial loads and unidirectional axial loads, often installed in pairs.

- Low friction: Optimised design and manufacturing processes reduce bearing friction while enhancing lubrication efficiency, thereby minimising noise and vibration.

- Extended service life: Featuring high rated load capacities, these bearings achieve prolonged durability through optimised contact stress between rollers and flanges.
