Product Description:
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.
Features
NMRV – Sizes: 025-030-040-050-130-150
NMRVpower – Sizes: 063-075-090-110
Available versions: fitted for motor coupling, with input shaft, with torque limiter
Power up to 15 kW
Max torque 1.550 Nm and admissible radial loads max 16.500 N
