Because tapered roller bearings can only bear unidirectional axial load, they are often used in pairs. DHK can provide paired single row tapered roller bearings on demand, face to face pairing (suffix DF), back to back pairing (suffix DB), and series (suffix DT) as shown below:

DHK tapered roller bearing adopts pressed steel cage, cage is slightly protruding to the side, so its installation size must be considered.
The width tolerance of the paired bearing is determined by the clearance and △Ts.
The clearance of a single row tapered roller bearing is set by adjusting another set of bearings used with it during installation.
The axial clearance of DHK bearing pairs face to face and back to back is shown in the table below. DHK can be customized with axial clearance as required.
