With 12 standard ratios from 5:1 to 100:1 and input power acceptance up to 0.55 kW, the NMRV040 handles applications that the smaller NMRV025 and NMRV030 cannot reach &#8211; belt conveyors running at moderate speeds, packaging machine fold-and-seal mechanisms, agricultural feed dispensers, and small mixer drives. The &Oslash;18 mm output shaft is the most common shaft size in small industrial drive systems, accepting standard couplings, sprocket hubs, and timing pulleys directly. Four output flange options &#8211; FA, FB, FC, and FD &#8211; provide direct machine mounting flexibility that eliminates the separate gearbox mounting bracket from the BOM. The NMRV040 also serves as the output stage for NMRV025\/040 and NMRV030\/040 double-stage combinations, and as a pre-stage for NMRV075 and NMRV090 in extreme-ratio configurations reaching 5000:1.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/reducers-worm.xyz\/wp-content\/uploads\/2026\/06\/nmrv-worm-gearbox-2.webp\" alt=\"EP-NMRV040 aluminium worm gearbox 40mm centre distance with
