Weighing only <strong>1.2 kg<\/strong>, it offers ratios extending to 100:1 and output torques up to <strong>60 Nm<\/strong>. Industrial buyers in Australia, the UK, and continental Europe consistently choose the NMRV030 as a drop-in replacement for obsolete geared motors. The standardised NEMA 48C input flange (inch) and IEC B14\/B5 compatibility (metric) mean virtually any locally sourced motor can be paired without custom adaptors.<\/p>\n<p style=\"font-size:clamp(14px,2vw,18px);line-height:1.8;word-break:break-word;\">Compared to the NMRV025, the NMRV030 adds a 100:1 ratio option and a significantly higher radial load capacity of up to 1,620 N, making it suitable for more demanding conveyor end-drive and agricultural auger applications where back-drive prevention at rest is also required.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/nmrv050gearbox.top\/wp-content\/uploads\/2026\/06\/nmrv-030-worm-gearbox-specification.webp\" alt=\"EP-NMRV030 worm gearbox dimension drawing and specification chart\" 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-NMRV030<\/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;\">1.2 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 0.18 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 60 Nm (at 100:1)<\/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 1,620 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.
