Thomas AMR/CMR


The ThomasĀ® AMR/CMR couplings are used in heavy duty slow to medium speed applications where shock loads, torque reversals or continuous alternating torque is present. New steel hub design allows larger bore capacity. CMR design uses a flywheel adapter plate to bolt directly to the flywheel of an engine or compressor.
