Matched tapered roller bearings arranged back-to-back (O-arrangement, load lines diverge toward the bearing axis) accommodate high radial loads, axial loads in both directions, and tilting moments. The precisely manufactured intermediate rings between the innner and outer rings enable a defined internal clearance or preload to be achieved when mounted. Matched tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills, and machines in the mining industry.
