NRV-VS Dual Double Solid Shaft Input Worm Gearbox with Flange Output 
- Quick stop function
For a general gear reducer, it takes 5 to 10 seconds for the stop time, but for the NRV series, the stop state could be reached in only 2 to 5 seconds. - High safety
The NRV worm gearbox adopts a different way compared with the traditional one in that it doesn't need the sprocket and pulley. What's more, the transmission structure is not exposed so that injuries to the operator could be reduced. - Good protection
Grade IP55 is adopted which has good isolation for dust and moisture. - Excellent thermal conductivity
The NRV worm gear is equipped with cooling ribs so that the body has excellent thermal conductivity and low temperature-rising. - Long service life
The worm gearbox operates smoothly with low noise which is suitable for long-term contact work in harsh environments.
