EPNRV075 Shaft-Input Aluminium Worm Reducer \u2014 Overview<\/h2>\n

The EPNRV075 is the most powerful unit in Ever-power’s EPNRV aluminium shaft-input worm reducer series, delivering up to 230 Nm of output torque from a 4.1 kW shaft input. At 9 kg with a 7,380 N output radial force capacity and the highest input shaft radial force rating in the series \u2014 980 N \u2014 the EPNRV075 is engineered for heavy industrial belt-drive and chain-drive applications where the input shaft must carry the radial load of a large V-belt drive or multi-strand roller chain. Widely used across Australian resources, port handling, and heavy manufacturing industries, the EPNRV075 provides the maximum shaft-input torque available in a single-stage compact aluminium worm gearbox.<\/p>\n
