NMRVNRV Worm Gear Reducer

Description

We specialize in manufacturing worm gear reducer, NMRV NRV Worm Reducer and NMRV Worm Reducer for many years in Taiwan

“NMRV and NMRV POWER worm gear reducers currently represent the most advanced solution to market requirements in terms of efficiency and flexibility.

The new NMRV Power series, also available as compact integral helical/worm option, has been designed with a view to modularity: low number of basic models can be applied to a wide range of power ratings guaranteeing top performance and reduction ratios from 5 to 1000.”
