At 13 kg with 90 mm centre distance, it remains 40% lighter than comparable cast iron units while handling industrial conveyor head drives, large agitator mechanisms, and renewable energy tracking systems. The &Oslash;35 mm output shaft with optional &Oslash;38 mm matches heavy-duty coupling and sprocket standards used across Australian industrial applications. IEC motor frames from 56 to 180 connect via B5 or B14 flange &#8211; the widest motor range in the mid-NMRV series. Four output flanges FA, FB, FC, FD and compatibility with PC080 helical pre-stages provide maximum configuration flexibility for demanding continuous-duty applications.<\/p>\n<p><img
