Nmrv Nrv Nmrv040 Worm Gear Speed Reduction Reducer Gearbox

EP-NMRV  REDUCTION WORM GEARBOX
The EP-NMRV 040 worm gear motor is characterized by a wide range of gear ratios (5 – 80), a compact aluminum alloy housing, and ease of installation and maintenance. The unit is equipped with an engine power of 0.09 – 0.55 kW. Output shaft rotation frequency: 900 – 2800 rpm.
The EP-NMRV 040 motor gearbox has similar mounting dimensions with the Siti MU40, STM UMI 40, Varvel SRT 40 drives and can be used to replace them.
Parts materials:
Case – aluminum, flanges – aluminum, worm – steel, worm wheel crown – bronze. 
Type of lubricant: synthetic ISO VG 320. 
Weight: 2.3 kg.
