Product Description

NMRV  REDUCTION WORM GEARBOX
The 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 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.
