Enlarged thickened die-cast aluminum housing
NMRV110 integrally cast thick aluminum casing with extended cooling ribs, larger inner cavity for more lubricant oil and stronger mechanical rigidity than smaller NMRV sizes.
Oversized tin bronze worm wheel set
Wear-resistant tin bronze worm wheel cooperates with precision ground alloy steel worm, bigger tooth contact area to sustain medium-heavy continuous load.
Versatile optional mounting parts
Standard hollow output shaft, solid shaft, torque arm and flange cover are optional for easy assembly with standard IEC motors.
Excellent heavy load capacity
Upgraded internal transmission parts deliver higher rated torque than NMRV075/090, ideal for medium agitators and heavy-duty conveyor equipment.
Stable temperature
Large oil storage space plus fast heat-conductive aluminum shell effectively control working temperature and reduce oil deterioration and leakage risks.
Secure self-locking protection
Built-in mechanical self-locking structure prevents reverse rotation triggered by dead load weight, effectively avoiding cargo falling accidents on lifting machinery.
Q:When is the first oil change required for NMRV110?
A: Replace lubricant after initial 300~500 working hours, then routine oil replacement every 3000 hours.
Q: Can NMRV110 and NRV110 replace each other with same motor power?
A:Same mounting dimension, only input structure differs; adaptor flange enables interchangeable installation.
Q: Does the gearbox need extra protection under dusty & humid working condition?
A:Double oil seals and dustproof covers are optional to stop dust and moisture inside casing.
