A 15:1 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.
