Rotary vane actuator

Pneumatic rotary vane actuators are characterized by their compact design. The energy of the compressed air is directly converted into a rotational movement via the vane. Vane drives therefore do not require an additional transmission ratio. For this reason, the compact and lightweight design is a major advantage. Vane drives easily achieve a swivel angle of 270°.
Festo is one of the world's leading manufacturers of rotary vane drives and offers the right solution for every application with its various series. Numerous additional functions also extend Festo's total product range in a targeted manner. These include a option with tandem vanes with a maximum torque of 80 Nm, a continuous hollow flange shaft for cable or media through-feed, a heavy-duty bearing for high load torques, and versions with ATEX approval for use in explosive atmospheres.

Rack and pinion actuators

In pneumatic rack and pinion actuators, the linear movement of a piston is converted into a swivel movement via a pinion. Drives with gear rack/pinion are used, for example, in custom handling systems where a swivel angle of up to 180° is required.
Rack and pinion actuators are characterized by their flat design, a continuous hollow flange shaft for cable or media through-feed as well as the simple attachment of the gripper to the actuator itself. This makes these rotary drives ideally suited, among other things, for pick & place applications or robot applications.
Festo is one of the world's leading manufacturers of rack and pinion actuators and offers the right solution for nearly every application with its various series. The bandwidth ranges from 0.2 to over 110 Nm torque. Various cushioning options enable suitable end-position cushioning for a wide range of applications. Depending on whether the focus is on the shortest possible swivel times or a high mass moment of inertia:
Numerous additional functions also extend Festo's total product range in a targeted manner. These include an intermediate position module, an integrated energy through-feed, and end-position locking.

Swivel actuator

Pneumatic swivel actuators combine the function of quarter turn actuators with the form of motion of a linear cylinder. This combination results in a compact unit with which swiveling and linear motion can be optimally matched to each other.
Festo is one of the world's leading manufacturers of swivel actuators. The performance ranges up to a torque of 20 Nm. Various cushioning options enable suitable end-position cushioning for a wide range of applications.
