EP-NRV110 — Shaft-Input Large-Frame Aluminium Worm Gear Reducer<\/h2>\n

El EP-NRV110<\/strong> is the shaft-input version of the NMRV110, sharing the same 110 mm centre distance, 9,232 N·m maximum output torque, and 7.5 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 NRV110 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 NRV090 at 90 mm centre distance, the NRV110 delivers 26% 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 NRV110 is particularly valued for large crane and hoist chain-driven travel mechanisms and high-power hydraulic-motor-driven industrial mixing and material handling 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
