Bearings of this type use conical rollers guided by a back face rib on the cone, These bearings are capable of taking high radial loads and also axial loads in one direction in the HR series. 'the rollers are increased in both size and number giving it an even higher load capacity They are generally mounted in pairs in a manner similar to single-raw angular Contact ball bearings. In this case, the proper internal clearance can be obtained by adjusting tht axial distance between the cones or cups of the two opposed bearings. Since they are separable. the cone assemblies and cups can be mounted independently Depending upon the contact angle tapered roller bearings arc, divided into three types called the normal angle, medium angle, and steep angle Double-raw and four-row tapered roller, bearings are also available. Pressed-steel cages are generally used.
