Product Description

NMRV  REDUCTION WORM GEARBOX
The NMRV 110 angular worm gear motor is designed to increase torque while reducing rotational speed. The drive is equipped with a single-stage gearbox and an electric motor with a power of 0.55 - 7.5 kW. The torque on the output shaft is 163 - 767 N * m. Gear Ratio Range: 7.5 - 100.
The NMRV 110 unit has the same mounting dimensions as the SITI MU105 and Varvel SRT 110 gearmotors, so it can be used to replace them.
Materials parts:
Body - iron, flanges - iron, worm - steel crown worm wheel - bronze. 
Type of lubricant: synthetic ISO VG 220. 
Weight: 35 kg.

Type designation scheme

NMRV - 110 - 40 - 35 - 1.5 - B6

• NMRV - worm gear motor
• 110 - size (center distance, mm)
• 40 - gear ratio
• 35 - output shaft rotation speed, rpm
• 1,5 - electric motor power, kW
• B6 - mounting position
