Product Description

NMRV  REDUCTION WORM GEARBOX
NMRV 150 CZPT motor for general industrial use refers to angular type drives. The unit provides high output torque (up to 1760 N * m), withstands significant radial loads (up to 18 000 N). Robust cast iron body gear motor has a protective coating. Mounting options: feet / flange.
Additional options:

• reactive rod for reactive torque compensation
• outlet flange for securing to the frame
• variator attachment for regulating the output shaft rotation speed
• torque limiter

Materials parts:
Body – iron, flanges – iron, worm – steel crown worm wheel – bronze. 
Type of lubricant: synthetic ISO VG 220. 
Weight: 84 kg.

Type designation scheme

NMRV – 150 – 7.5 – 186.7 – 15 – B7

• NMRV – CZPT motor
• 150 – size (center distance, mm)
• 7.5 – gear ratio
• 186.7 – output shaft rotation speed, rpm
• 15 – electric motor CZPT , kW
• B7 – mounting position
