At <strong>2.3 kg<\/strong>, it is light enough to be hand-installed by a single technician yet produces output torques reaching <strong>129 Nm<\/strong> with a 0.37 kW motor at its highest reduction ratio.<\/p>\n<p style=\"font-size:clamp(14px,2vw,18px);line-height:1.8;word-break:break-word;\">What distinguishes the NMRV040 within the series is its notably wider output flange configuration menu \u2014 four variants (FA, FB, FC, FD) \u2014 giving design engineers the freedom to match driven-machine bolt patterns without machining custom adaptors. Paired with both metric 18 mm and 0.750 in inch output shaft options, and accepting both IEC B14\/B5 and NEMA 56C motor flanges, the NMRV040 is a genuinely universal worm gear reducer suited to global OEM programmes and local Australian replacement scenarios alike.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/nmrv050gearbox.top\/wp-content\/uploads\/2026\/06\/nmrv-040-worm-gearbox-specification-1.webp\" alt=\"EP-NMRV040 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-040-worm-gearbox-specification-2.webp\" alt=\"EP-NMRV040 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-NMRV040<\/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;\">2.3 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 0.55 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 129 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 3,118 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.
