Type of arrangement Universally matchable bearings and matched bearing sets can be arranged in various combinations depending on the stiffness, rigidity and load requirements of the application. The possible combinations are shown in fig. 1, including the designation suffixes applicable to matched bearing sets.

Back-to-back bearing arrangement In a back-to-back bearing arrangement, the load lines diverge toward the bearing axis. Axial loads acting in both directions can be accommodated, but only by one bearing or bearing set in one direction each. Bearings mounted back-to-back provide a relatively rigid bearing arrangement that can also accommodate tilting moments.

Face-to-face bearing arrangement In a face-to-face bearing arrangement, the load lines converge toward the bearing axis. Axial loads acting in both directions can be accommodated, but only by one bearing or bearing set in one direction each. Face-toface arrangements can accommodate small amounts of deflection. 

Tandem bearing arrangement In a tandem bearing arrangement, the load lines are parallel so that radial and axial loads are shared equally by the bearings in the set. The bearing set can only accommodate axial loads acting in one direction. If axial loads act in the opposite direction, or if combined loads are present, additional bearing(s) adjusted against the tandem arrangement should be added.
