A rotating measurement finder developed by ABB, dubbed the Bearing Compass, makes the identification of housed bearings straight forward, aiding in the selection of appropriate replacement units. All the common bearing types and designations are listed, with the common references and sizes of standard housed bearings included.

The second Bearing Compass, features the ABB Dodge 2-bolt and 4-bolt flange housing ball bearings with standard shaft-mount inserts. These are dimensionally identical to standard bearings and are directly interchangeable with most existing housed bearings on the market.
