Pneumatic rotary drives from Festo enable rotary movements with a swivel angle of up to 270°. Both rotary vane drives and rack-and pinion drives typically achieve maximum precision while also offering excellent performance and great versatility. As a result, our pneumatic drives are used in factory automation across a wide range of industries.

The impressive features of our compact rotary drives include installation in tight spaces, high permissible mass moments of inertia and the sensing option. Selected types are also available in a modular design with additional functions or are suitable for potentially explosive atmospheres in accordance with the ATEX directive.
Festo rotary vane cylinders are compact and affordable drives available in two series: the DRVS series consists of rotary drives that are optimised for swivelling and are especially lightweight and compact. The swivel angle is either fixed or can be adjusted with the help of optional accessories. The DSM series offers lots of optional functions, including especially powerful hydraulic cushioning for high energy. The swivel angles of the DSM rotary drives are infinitely adjustable over the entire swivel range and deliver high precision thanks to fixed metal stops.
Our rotary drives which operate on the rack-and-pinion principle boast very high accuracy in the end positions, maximum load capacity of the bearing, very good axial run-out at the output shaft and high mass moments of inertia thanks to powerful cushioning. The DRRD series offers lots of optional functions that simplify use in handling and assembly technology: centre positioning module, energy through-feed, etc. With variable mounting options, the twin-piston drives are perfect in combination with other Festo drives and grippers.
The Festo swivel/linear units DSL are a combination of a compact rotary drive with vane technology and a linear cylinder. They offer high repetition accuracy thanks to cushioning components with fixed stops. The swivel angles can be infinitely and accurately set. A simple plain-bearing guide or precise recirculating ball bearing guide makes swivelling up to 270° and linear strokes up to 200 mm possible.
对于摆动气缸和直线摆动组合气缸，气流的精准控制是实现平稳运行的前提。 通过阀流量控制，您可在无需重新设计该组合装置的情况下，精确调节摆动运动和直线行程部分。 基于速度控制阀的气动配置（通常为气动节流阀或气动节流装置）可作为实用的气缸速度控制器，实现稳定的运动与可重复的动作时序。
如果您的装置配备气缸行程或磁性活塞传感功能，那么通过终端位置反馈，就能有效避免动作节拍发生偏移。 使用气缸传感器作为气缸限位开关。 这些气缸终端位置传感器（常用作气缸的限位开关）通常利用气缸用舌簧开关来检测活塞磁铁，并在每个停止位置提供清晰的信号。 它们可用作气缸行程终端位置传感器，也是可靠的气缸限位开关选项。
