Tapered roller backing bearings

Tapered roller backing bearings (fig 1) are basically double row tapered roller bearings of the TDO design (back-to-back arrangement) and are consequently able to accept the axial loads which occur in operation as well as heavy radial loads. They are sealed at both sides with pressed steel washers. Lubrication grooves in the inboard inner ring side faces facilitate lubricant supply to the bearing.
