EP-NRV063 — Shaft-Input Medium-Duty Aluminium Worm Gear Reducer<\/h2>\n

El EP-NRV063<\/strong> is the shaft-input version of the NMRV63, sharing the same 63 mm centre distance, 5,595 N·m maximum output torque, and 2.2 kW input power rating in an identical die-cast aluminium housing, but configured with a solid keyed input shaft in place of the bore-input IEC flange. This configuration makes the NRV063 the natural choice when power arrives via chain sprocket, belt pulley, hydraulic motor output, or PTO-driven countershaft — driving arrangements that cannot present an IEC flange face to the gearbox. Compared with the NRV050 at 50 mm centre distance, the NRV063 delivers 31% more output torque, enabling it to handle heavier chain-driven loads while maintaining the NRV series’s lightweight aluminium housing and corrosion-resistant finish. In Australian industry, the NRV063 is particularly valued for print and packaging line chain drives and agricultural machinery driven by PTO countershafts, where the solid shaft input integrates naturally into existing chain or belt drive train layouts without requiring an IEC motor adaptor or modifying the drive geometry.<\/p>\n
