1. 2-stage or 3-stage helical & hypoid bevel gear set, large reduction ratio
2. Hardened gears, higher gear hardness and strength than NMRV series worm gears. Wearable and long service life
3. Energy efficient. The efficiency is more than 90%. About 10%~40% efficiency difference compared with NMRV series worm gearbox
4. Modular design, various combinations
5. Mounting dimensions are compatible with NMRV series (Except KM050 and NMRV050)
6. High efficiency KM series can replace NMRV series in wide applications
