Overview
The Sumitomo N2AGCYS-2-1/4 Beier-Cyclo Variator is a compact variable-speed gearmotor combining a Beier Variator with a Cyclo speed reducer. This 1/4 horsepower unit delivers adjustable speed control and extremely low output speeds for precision automation. The viscous-friction oil-film design eliminates wear on transmission discs, ensuring long service life with minimal maintenance—ideal for packagers, conveyors, and process equipment.
Key Features
- Viscous-friction transmission with multiple disc contact points minimizes surface pressure and wear
- Smooth variable speed adjustment throughout operating range
- Extremely low output speeds via integral Cyclo reducer
- Reliable 3-phase motor compatible with standard industrial power
- Foot-mount or flange-mount configurations available
- Minimal maintenance requirement—constant oil film prevents disc grooving
