Motovario NMRV-P110 20:1 Worm Gearbox – 42mm Output Bore
Built for smooth and dependable mechanical speed reduction, this Motovario NMRV-P110 20:1 worm gearbox is ideal when you need balanced output speed reduction with useful torque increase. Its 42mm 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 NMRV-P110 gearbox combines a higher-capacity frame size with a 20:1 reduction stage, making it suitable for conveyors, mixers, processing equipment, heavier automation systems. It is typically chosen where a practical compromise between output speed and torque is needed, especially where installation space is limited and a right-angle drive is preferred.
Why Choose This Configuration?
A 20:1 worm gearbox is typically chosen when the application needs balanced output speed reduction with useful torque increase. Compared with lower ratios it trades output speed for more torque multiplication, while compared with higher ratios it retains a more practical shaft speed for general machinery.

Frequently Asked Questions
What does a 20:1 worm gearbox do?
A 20:1 worm gearbox reduces motor speed and multiplies torque, giving slower and more controlled output for industrial machinery.
What is this NMRV-P110 gearbox commonly used for?
This gearbox is commonly used on conveyors, mixers, processing equipment, heavier automation systems, 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.
