Product Description

NMRV  REDUCTION WORM GEARBOX
The NMRV 090 worm gear motor is an angular drive in which the input and output shafts are at right angles to each other. A gearbox with one gear stage provides gear ratios of 7.5 - 100. Electric motor power: 0.37 - 4 kW. The drive can be mounted in an arbitrary spatial position. Mounting options: flange or feet.
The unified mounting dimensions provide the NMRV 090 gearmotor interchangeability with Varvel SRT 85, STM UMI 90, SITI MU90 units.
Parts materials:
Case - aluminum, flanges - aluminum, worm - steel, worm wheel crown - bronze. 
Type of lubricant: synthetic ISO VG 320. 
Weight: 13 kg.

Type designation scheme

NMRV - 090 - 30 - 93.3 - 2.2 - B7

• NMRV - worm gear motor
• 090 - size (center distance, mm)
• 30 - gear ratio
• 93.3 - output shaft rotation speed, rpm
• 2.2 - electric motor power, kW
• B7 - mounting position
