Product Description

Chrome steel taper Roller Bearing 710mm Bore High Precision


Detailed Product Description


Tapered roller bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.


Taper roller bearing comprise solid inner and outer rings with tapered raceways and tapered rollers with cages. The bearings are not self-retaining. As a result, the inner ring together with the rollers and cage can be fitted separately from the outer ring. Taper roller bearing can support axial loads from one direction as well as high radial loads
