Weighing <strong>3.5 kg<\/strong>, it bridges the gap between the lighter NMRV040 and the substantially larger NMRV063, offering a <strong>25 mm output shaft<\/strong> that matches the most common driven-shaft diameter in mid-duty industrial equipment across Australia, continental Europe, and Southeast Asia.<\/p>\n<p style=\"font-size:clamp(14px,2vw,18px);line-height:1.8;word-break:break-word;\">With output torques reaching <strong>290 Nm<\/strong> at the 100:1 ratio and a maximum radial load of 4,280 N on the output shaft, the NMRV050 handles demanding applications that would overtax the NMRV040 without requiring the bulk and cost of the NMRV063. Its four output flange options (FA, FB, FC, FD) and dual metric\/inch shaft availability make it a highly configurable worm gear reducer for OEM machinery builders targeting both Australian and export markets.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/nmrv050gearbox.top\/wp-content\/uploads\/2026\/06\/nmrv-050-worm-gearbox-specification-1.webp\" alt=\"EP-NMRV050 worm gearbox specification drawing sheet 1\" style=\"max-width:100%;height:auto;display:block;margin:16px auto;\" \/><br \/>\n<img decoding=\"async\" src=\"https:\/\/nmrv050gearbox.top\/wp-content\/uploads\/2026\/06\/nmrv-050-worm-gearbox-specification-2.webp\" alt=\"EP-NMRV050 worm gearbox specification drawing sheet 2\" style=\"max-width:100%;height:auto;display:block;margin:16px auto;\" \/><\/p>\n<h2 style=\"font-size:clamp(18px,3vw,26px);color:#1a3c6e;border-bottom:3px solid #1a3c6e;padding-bottom:8px;\">Technical Specifications<\/h2>\n<div style=\"overflow-x:auto;\">\n<table style=\"width:100%;border-collapse:collapse;font-size:clamp(13px,1.8vw,16px);\">\n<thead>\n<tr style=\"background:#1a3c6e;color:#fff;\">\n<th style=\"padding:10px;border:1px solid #ccc;text-align:left;\">Parameter<\/th>\n<th style=\"padding:10px;border:1px solid #ccc;text-align:left;\">Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:#f5f7fa;\">\n<td style=\"padding:9px;border:1px solid #ddd;\">Model<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">EP-NMRV050<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border:1px solid #ddd;\">Weight (without motor)<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">3.5 kg<\/td>\n<\/tr>\n<tr style=\"background:#f5f7fa;\">\n<td style=\"padding:9px;border:1px solid #ddd;\">Gear Ratios<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">5, 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border:1px solid #ddd;\">Max Input Power (P1)<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">Up to 0.75 kW<\/td>\n<\/tr>\n<tr style=\"background:#f5f7fa;\">\n<td style=\"padding:9px;border:1px solid #ddd;\">Max Output Torque (M2)<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">Up to 290 Nm<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border:1px solid #ddd;\">Output Speed Range<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">14 \u2013 280 rpm (at 1400 rpm input)<\/td>\n<\/tr>\n<tr style=\"background:#f5f7fa;\">\n<td style=\"padding:9px;border:1px solid #ddd;\">Max Radial Load Fr2<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">Up to 4,280 N<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border:1px solid #ddd;\">Housing Material<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">Die-cast aluminum alloy<\/td>\n<\/tr>\n<tr style=\"background:#f5f7fa;\">\n<td style=\"padding:9px;border:1px solid #ddd;\">Worm Wheel Material<\/td>\n<td style=\"padding:9px;border:1px solid #ddd;\">Phosphor bronze<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border:1px solid #ddd;\">Output Shaft Dia.
