Highly efficient compact NMRV/NMRV-P worm gear series with aluminum or cast iron housing for reliable and quiet operation.
- Product description
- FAQ
The NMRV series is designed for power transmission in a compact form, with various configuration and module options that allow customization to specific requirements. The housings are made of aluminum alloy (smaller sizes) or cast iron (larger sizes), providing an optimal balance between weight and strength. They feature a wide range of gear ratios, easy installation in different positions, and compatibility with other reducers. NMRV reducers come with a pre-mounted connection for asynchronous IEC motors, while the NMRV-P has a modular design, requiring the selection of a flange and input shaft bushing depending on the chosen IEC motor.
Features and Benefits
- Aluminum housing (sizes 025–110) or cast iron (sizes 130–150)
- Torque transmission up to 2,700 Nm
- Gear ratios up to 1083:1
- Compact design and low weight
- Multiple mounting positions possible
- Low noise and vibration levels
- Modular construction with optional accessories and combinations
- Easy maintenance and long service life
Applications
- Conveyor belts and material handling lines
- Packaging and filling industry
- Ceramics and glass industry
- Woodworking and processing industry
- Agricultural and food-processing machinery
- Lifts, doors, and automation
- Water treatment and pumping systems
