Series AMR Download PDFCatalogue No.:UT-AMR | Revision 00

Type AMR Couplings are designed for heavy duty applications at slow to medium speeds. These are very suitable for heavy duty motor and diesel engine drives with high starting torques , shock load or reversing load. The open lug type center member gives adequate clearance for bolt removal while requiring minimum space for machine installation.The center member can be removed without having to shift connected machines.
