NMRV series worm gear reducer

The NMRV and NMRVpower worm speed reducers represent the most advanced solutions to market demand in terms of efficiency and flexibility. The new NMRVpower series, the helical gear / compact worm can also be used, and has designed a modular view: the basic models of small rated power is applicable to a wide range, to ensure optimal performance, reduction ratio range from 5 to 1000.
