Four-row tapered roller bearings are capable of carrying combined radial and axial loads at low to medium speeds. They are used only in work roll equipment applications such as rolling mills. JOJI manufactures four-row tapered roller bearings of types TQO and TQI in many variants and with different characteristics.

• High radial load carrying capacity
• Capable of withstanding bi-directional axial loads
• Saving of axial space for roll necks
• Long service life
