At <strong>13&nbsp;kg<\/strong>, it remains light enough for a two-person installation without lifting equipment yet delivers output torques of up to <strong>1,000&nbsp;Nm<\/strong> &mdash; a specification that previously demanded heavy cast iron reducers weighing 35&nbsp;kg or more. This torque-to-weight step-change makes the NMRV090 particularly attractive for Australian process industries where remote or elevated installation points make weight a real operational constraint.<\/p>\n<p style=\"font-size:clamp(14px,2vw,18px);line-height:1.8;word-break:break-word;\">The NMRV090 is the first model in the NMRV series to offer a <strong>35&nbsp;mm primary output shaft<\/strong> as standard &mdash; matching the driven-shaft bore of heavy-duty industrial sprockets, timing pulleys, and pump impeller hubs in the 3&ndash;5.5&nbsp;kW motor range. Combined with four output flange configurations (FA, FB, FC, FD) covering pilot diameters from 130 to 180&nbsp;mm, and acceptance of three NEMA input standards (56C, 140TC, 180TC), the NMRV090 delivers unprecedented configurability for a compact aluminum worm gear reducer.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/nmrv050gearbox.top\/wp-content\/uploads\/2026\/06\/nmrv-090-worm-gearbox-dimensions.webp\" alt=\"EP-NMRV090 worm gearbox dimension drawing and specification\" 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;word-break:break-word;\">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-NMRV090<\/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;\">13 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;\">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 4.0 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 1,000 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 &ndash; 186.7 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 7,306 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.
