This design is based on a system with a multiple helical gear. The linear movement of the piston is converted into a rotational movement via the multiple helical gears. The rotational movement will be greater if the linear movement of the piston is longer.
The design of our rotary actuators is very simple, but requires precision manufacturing in order to ensure their functional efficiency and brand-name reliability. The rotational play of the multiple gear rotary actuators can be reduced to 10 angular minutes.
