Double-row and four-row tapered roller bearings

Double-row and four-row tapered roller bearings

Inch taper roller bearing, its apparent feature is the dimesion is not standard. Their components are same as metric taper roller bearing. Inch taper roller bearings are divided into single row, double row and four row types.

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 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-row angular contact ball bearings. In this case, the proper internal clearance can be obtained by adjusting the 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 are divided into three types; Normal angle, medium angle, and steep angle.

Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used.
