EPNMRV050 Aluminium Worm Gearbox \u2014 Overview<\/h2>\n

Designed for the demands of food processing lines and pharmaceutical manufacturing, the EPNMRV050 aluminium worm reducer delivers IP-friendly sealed performance in environments where hygiene and regular washdown are non-negotiable. At 3.5 kg and rated to 0.75 kW, this mid-range model produces up to 81 Nm of output torque across twelve standard reduction ratios, making it the most popular EPNMRV size among OEM bottling line integrators and conveyor drive manufacturers across Asia-Pacific. The smooth, low-noise worm gear set minimises vibration transmission to sensitive processing equipment, and four output flange options (FA through FD) allow direct connection to conveyor rollers, eliminating intermediate couplings that trap food product.<\/p>\n
