Series 80 CMR SPL Download PDFCatalogue No.:UT-80 CMR SPL | Revision 00

Type CMR Couplings are similar to the Type AMR  except that one hub is substituted by a flange adaptar plate . This makes the coupling specially suitable for direct attachment to the Flywheel of engines , reciprocating compressors etc without an extension shaft.
