Product Description
These Tapered roller bearings are separate, and the inner and outer rings of the bearing have tapered raceways.
This type of bearing is divided into different structural types such as single-row, double-row, and four-row tapered roller bearings according to the number of rows of rollers installed.
Tapered roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads.
Papermaking machinery, speed reducer, railway vehicle axle, gear box bearings, rolling mill rolls, crusher, vibrating screens, printing machinery, woodworking machinery, and all kinds of industry.
