This type of bearing comprises tapered rollers guided by the shoulders of the inner ring. Tapered roller bearings can support both radial and axial loads in one direction. A second bearing is usually mounted in opposition to the first to guide the shaft and to take up axial forces in the other direction. These bearings have separable rings, since the cone and cup can be mounted separately. Various types of tapered roller bearings are also supplied matched in X arrangement with a defined axial clearance.
The internal clearance of tapered roller bearings is fixed when the bearings are mounted. For X-bearings, the radial clearance is determined by the spacer mounted between the two cups.
Tapered roller bearings have a pressed steel cage. It may protrude slightly from the side faces of the bearing.
