EPNMRV090 Worm Gearbox \u2014 Product Overview<\/h2>\n

Positioned as the primary torque carrier for mid-range industrial automation, the EPNMRV090 worm gearbox offers a 90 mm centre distance, rated output torque up to 479 Nm, and a 13 kg aluminium housing engineered for continuous-duty manufacturing environments. Australian system integrators specify the EPNMRV-090 for assembly-line indexing tables, robotic auxiliary drives, cut-to-length feeders, CNC load-unload systems, and automated guided vehicle (AGV) traction axles where repeatability, low backlash drift over time, and thermal stability all matter. The EPNMRV090 accepts NEMA 56C, 140TC, and 180TC input flanges and supports six mounting positions, making it straightforward to integrate into either new designs or retrofit projects. Its eleven available reduction ratios from 7.5:1 to 100:1 \u2014 combined with generous 7,306 N radial-load capacity at the output shaft \u2014 allow engineers to eliminate chains, sprockets, and belt tensioners that would otherwise add maintenance burden on a 24\/7 line.<\/p>\n

Lead application focus: assembly-line indexing tables and robotic auxiliary drives<\/strong> in the Industrial Automation & Manufacturing<\/strong> sector across the Australian industrial market.<\/p>\n
