Single row taper roller bearing inch series
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.
