NMRV Series Worm Gear Reducer

NMRV Series Worm Gear Reducer

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.

NMRV series worm gear reducer has the following main features: high-quality aluminum alloy casting, light weight, corrosion and oxidation resistance, no rust; high output torque; smooth transmission, low noise, suitable for long-term continuous work in harsh environments; high efficiency of heat dissipation; beautiful and durable, small size; can be adapted to all-round installation.

Advantages:

1.High modular design
2.High loading support, stable transmitting and low noise level.
3.Excellent sealing, wide range of industry application.
4.High efficiency and save power.
5.Save cost and low maintenance.
