Product Description

NMRV  REDUCTION WORM GEARBOX
The NMRV 050 motor gearbox consists of a single-stage NRV 050 CZPT box coupled to an IEC asynchronous motor. CZPT imum drive CZPT – 1.5 kW. The torque on the output shaft is 17-89 N * m. The gear motor is CZPT in two mounting versions (legs / flange).
Parts materials:
Case – aluminum, flanges – aluminum, worm – steel, worm wheel crown – bronze. 
Type of lubricant: synthetic ISO VG 320. 
Weight: 3.5 kg.
