31307/DF Matched taper roller bearing

Advantage: large radial and axial loads

Product Detail

The modified contact line between roller and raceway can reduce the stress concentration, and the tapered roller bearing can bear large radial and axial loads. Since the tapered roller bearing can only transmit one-way axial load, in order to transmit the axial load in the opposite direction, it is necessary to install another tapered roller bearing symmetrically with it.
