Motovario NMRV050 100:1 Worm Gearbox – 25mm Output Bore
Built for smooth and dependable mechanical speed reduction, this Motovario NMRV050 100:1 worm gearbox is ideal when you need very low output speed with maximum torque multiplication. Its 25mm output bore, modular IEC input arrangement and durable die-cast aluminium construction make it a practical choice for machinery builders and replacement projects.
Gearbox Overview
This NMRV050 gearbox combines a medium-duty frame size with a 100:1 reduction stage, making it suitable for conveyors, packaging machinery, feeders, small mixers. It is typically chosen where high torque and slow, controlled output are the priority, especially where installation space is limited and a right-angle drive is preferred.
Why Choose This Configuration?
Choose this version when you need the mechanical fit of a NMRV050 unit together with a 100:1 reduction and 25mm bore size. It is intended for applications where high torque and slow, controlled output are the priority, without moving into a different gearbox size unnecessarily.

Frequently Asked Questions
What does a 100:1 worm gearbox do?
A 100:1 worm gearbox reduces motor speed and multiplies torque, giving slower and more controlled output for industrial machinery.
What is this NMRV050 gearbox commonly used for?
This gearbox is commonly used on conveyors, packaging machinery, feeders, small mixers, where compact right-angle transmission and dependable continuous-duty operation are important.
What mounting positions are available?
Motovario lists B3, B6, B7, B8, V5 and V6 mounting positions for these NMRV/NRV units, with B3 technically preferred for lower oil splash, better lubrication and less heating.
What lubricant is supplied as standard?
These units are supplied with synthetic ENI TELIUM VSF lubricant for life under standard conditions.
What material is the housing made from?
Sizes up to 110 use die-cast aluminium alloy housings, while sizes 130 and 150 use grey cast iron housings.
