EP-NRV150 — Flagship Shaft-Input Maximum-Torque Aluminium Worm Gear Reducer<\/h2>\n

The EP-NRV150<\/strong> is the shaft-input version of the NMRV150, sharing the same 150 mm centre distance, 16,508 N·m maximum output torque, and 15 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 NRV150 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 NRV130 at 130 mm centre distance, the NRV150 delivers 37% 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 NRV150 is particularly valued for port bulk material conveyor chain drives and large crane hoist chain systems and primary sludge treatment and high-power industrial reactor chain-driven mixing equipment, 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
