Understanding Back-to-Back & Face-to-Face Bearing Arrangements …

10/3/2021· Face-to-face arrangement: Also known as an X arrangement, this is known to tolerate misalignments and cannot support moment loads as effectively as back-to-back arrangements. If misalignment cannot be avoided between the bearing positions, face-to-face bearing arrangements are recommended (see Image 3).
