It represents the most specialised configuration in the four-variant series: combining the <strong>solid 11 mm solid input shaft<\/strong> of the NRV series with the <strong>coaxial inline output<\/strong> of the NMRV-E series. The result is a worm gearbox that operates as a pure inline shaft-coupled reduction stage \u2014 accepting a shaft coupling, chain sprocket, or belt pulley on the input and delivering reduced speed on the same axis at the output, with no motor flange projection at either end and no 90-degree shaft offset. This configuration is engineered for inline belt-driven pump trains, compact mixer shaft chains, automated machinery inline drives, and multi-stage gear systems where the complete drive train must maintain a single shaft axis from source to load. With output torques up to <strong>400 Nm<\/strong>, ratios from <strong>5\u2013100:1<\/strong>, die-cast aluminium A360 housing, and IP65 shaft sealing, the EP-NRV-E040 serves inline shaft-coupled drives on compact pump and process machinery across Australia and international markets. All six mounting positions are supported for maximum installation flexibility.<\/p>\n<div style=\"clear:both;\"><\/div>\n<\/div>\n<div

Ultimate Inline Shaft Drive<\/h3>\n<p style=\"font-size:13px;color:#444;font-family:Arial,sans-serif;line-height:1.6;margin:0;\">The EP-NRV-E040 combines both specialised features: a solid 11 mm solid input shaft (no motor flange) and a coaxial inline output shaft. This dual configuration produces the most compact possible inline shaft-coupled worm gearbox \u2014 ideal for multi-stage gear trains and inline shaft drives where both ends must be on the same axis with no flange projection.<\/p>\n<\/div>\n<div style=\"flex:1 1 260px;max-width:380px;background:#eef6fb;border-left:4px solid #0d3d5c;padding:calc(2%+8px);box-sizing:border-box;border-radius:4px;word-break:break-word;\">\n<h3 style=\"font-size:14px;color:#0d3d5c;font-family:Arial,sans-serif;margin:0 0 6px;\"><span style=\"color:#c0392b;margin-right:6px;\">&#9651;<\/span>Shaft-to-Shaft Inline Reduction \u2014 No Axis Deviation<\/h3>\n<p style=\"font-size:13px;color:#444;font-family:Arial,sans-serif;line-height:1.6;margin:0;\">Unlike right-angle units, the NRV-E040 receives and delivers power along a single axis. Solid input shaft accepts couplings, sprockets, and pulleys; coaxial output connects to the driven load shaft. The result is a reduction stage that slots into any inline shaft train without introducing a 90-degree offset or motor flange bracket at either end.<\/p>\n<\/div>\n<div style=\"flex:1 1 260px;max-width:380px;background:#eef6fb;border-left:4px solid #0d3d5c;padding:calc(2%+8px);box-sizing:border-box;border-radius:4px;word-break:break-word;\">\n<h3 style=\"font-size:14px;color:#0d3d5c;font-family:Arial,sans-serif;margin:0 0 6px;\"><span style=\"color:#c0392b;margin-right:6px;\">&#9670;<\/span>Corrosion-Resistant Die-Cast Aluminium Housing<\/h3>\n<p style=\"font-size:13px;color:#444;font-family:Arial,sans-serif;line-height:1.6;margin:0;\">A360 die-cast aluminium provides inherent corrosion resistance for food processing, coastal, chemical, and humid environments.
