1.Structure features,
High quality die casting aluminum alloy housing,suitable for universal mounting.
Heat sink design for cooling provides great surface area and higher thermal capacity than the casting iron housings.
From Nmrv025-150 with power scope from 15KW-60KW.
Large speed ratio range.Each single frame size has 12 ratios from 5:1 to 100:1
Hardened worm with find grinding has the features of higher efficiency and big output torque.
Low noise and stably running,can adapt long term work condition in terrible environments.
Modularization combination PCRV+DRV extend the ratio of NMRV reducers from 5:1 to 3200:1
