Cycloidal gear technology

Sumitomo Cyclo gears work by sharing the load across its reducer components. This makes them more compact, durable and precise than conventional cog gears.

Cyclo gears provide high reduction ratios in a single stage, often ranging from 30:1 to over 100:1, and even higher in multi-stage configurations.

The benefits of cycloidal gear technology

Sumitomo Cyclo gears outperform conventional gears. Due to their rolling motion, cycloidal gears have a significant advantage over cogwheel gears. Today, they’re considered a proven solution that should be favoured over other gear types in a number of scenarios – for good reason.
