Rotary actuators for precise rotation

Our rotary actuators convert the linear motion of pneumatic cylinders into a defined rotary motion. The rotary motion is transmitted via an externally guided shaft for power transmission.

How it works

The rotary actuator consists of two single-acting cylinders connected to each other via a rack. The rack engages with a gear that is mounted in the central middle block.

As the pistons extend and retract, the rack moves linearly. This movement is transmitted to the gear via the toothing and converted into rotary motion. The gear is rigidly connected to a shaft that is guided to the outside and transmits the required torque to the respective application.

Individually definable angle of rotation

The achievable angle of rotation is largely determined by the stroke length of the cylinders used. This allows the rotary actuator to be adapted to different requirements and motion sequences.

For reliable end-position monitoring, both end positions can be monitored via magnetic switches. Depending on the version, cushioned piston end positions or magnetic pistons are also available.

Precise motion for custom applications

Whether for mechanical engineering, automation technology, or special custom applications: rotary actuators offer a compact way to convert linear cylinder movements into controlled rotations.
