Tandem arrangement Bearings

Tandem bearing arrangement (also known as “DT arrangement”) is a type of duplex bearing arrangement where the two half are placed so that contact angle lines are parallel.

The use of a tandem arrangement provides increased axial and radial load carrying capacity compared to a single bearing. In a tandem arrangement , the load lines are parallel so that radial and axial loads are shared. The bearing set can only accommodate axial loads acting in one direction. If axial loads act in both directions, or if combined loads are present, additional bearing(s) adjusted against the tandem arrangement must be added.
