H1: Cast Iron NMRV Worm Gearbox – Heavy Duty Speed Reducer for Demanding Applications

What Is Cast Iron NMRV Gearbox?

Cast iron NMRV is a right-angle worm gear speed reducer with a high-strength grey cast

 iron housing (机座号110–150). Unlike standard aluminum NMRV (025–090) used for light 

to medium duty, cast iron NMRV is engineered for heavy loads, vibration, shock, dust, and

 continuous 24/7 operation

1.Key distinction: Same modular design as aluminum NMRV – interchangeable mounting dimensions –

 but with dramatically higher strength and durability.

2.Common names: Cast iron worm gearbox, heavy duty NMRV, NMRV110/130/150, cast iron speed 

reducer.

3.Typical applications: Heavy conveyors, industrial mixers, crushers, mining equipment, cement plants,

steel mills, and large agitators.

FAQ

Q: What sizes are available in cast iron NMRV?

A: Cast iron housing is used for NMRV110, NMRV130, and NMRV150. Sizes 025–090 use aluminum alloy.

Q: Is cast iron NMRV interchangeable with aluminum NMRV of the same size?

A: Yes – mounting center height and flange dimensions are identical. Only net weight differs.

Q: What material is the cast iron housing?

A: High-strength grey cast iron (HT200) via integral casting, providing dense structure and superior rigidity.
