Family specifications and selection conditions
| Product description | Four-row tapered roller bearings can accommodate combined heavy radial and axial loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills. SKF manufactures four-row tapered roller bearings in TQO and TQI designs, in many variants and with different features. |
|---|---|
| Manufacturer features | Very high radial load carrying capacity • Accommodate axial loads in both directions • Axial space-saving solution for roll necks • Low friction • Long service life |
