Robust SW worm gear drives with aluminum housing and wide range of gear ratios, for high loads and long-term operation.
- Product description
- Technical details
- Documents
- FAQ
The SW series consists of worm gear reducers with aluminum housing, designed for transmitting high torques and operating in heavy industrial conditions. These reducers feature a round shape (unlike the NMRV, which is square) and provide resistance to mechanical stress, flexible configuration options, and easy connection with other gearboxes from the Motovario range. They are suitable for long-term use with minimal maintenance, offering stable transmission at low and medium speeds. CD (Clean Duty) versions with stainless steel housing are available for food-processing environments.
Features and Benefits
- Aluminum housing for reduced weight
- Torque transmission up to 2,700 Nm
- Gear ratios up to 1083:1
- Available in sizes from 030 to 110
- Designed for heavy-duty loads and industrial environments
- Can be combined with other reducers
- Good resistance to vibrations and mechanical stress
- Long service life with minimal maintenance
Applications
- Transport and logistics systems
- Lifting equipment, winches, and load-handling systems
- Concrete and construction machinery
- Glass, ceramics, and stone industries
- Machine tools and production lines
- Packaging, filling, and food-processing equipment
- Mining, cement, and heavy industries
