Pneumatic cylinders are components that carry out a movement using compressed air, which is why they are also known as compressed air cylinders. Pneumatic drives are an especially cost-effective solution for a number of application areas – even in extremely tough ambient conditions – and stand out for being really simple to commission. Speeds of between 10 mm/s and 3 m/s can be achieved. Pneumatic cylinders are sturdy and flexible thanks to the compressibility of the air, which also makes them resistant to high external forces.
Pneumatic cylinders are used in numerous applications in automation technology/factory automation. Typical application areas for pneumatic drives are clamping, lifting, countersinking, pushing, pulling, feeding, turning, gripping, clamping and holding, joining, stopping, stamping, embossing and many others.
The range of pneumatic cylinders drives at Festo includes piston rod and rodless cylinders (linear drive), rotary cylinders, tandem, multi-position and stopper cylinders, as well as clamping cylinders, drives with linear guides, and bellows and diaphragm cylinders. As part of the range, we offer many standards-based cylinders with standardised dimensions and mounting interfaces. Cylinders that comply with a specific standard have identical dimensions. There are standards for piston rod cylinders with round design (ISO 6432), compact design (ISO 21287) and for profile and tie rod cylinders (ISO 15552).
Festo piston rod cylinders are pneumatic drives for executing linear movements. The energy applied to the piston is transferred by a piston rod to the parts to be moved. Piston rod cylinders are available as round cylinders, profile cylinders, compact cylinders, short-stroke cylinders, flat cylinders, miniature cylinders, cartridge cylinders or stainless-steel cylinders.
Rodless cylinders are pneumatic cylinders and – as the name suggests – do not have a piston rod. But even without a piston rod they execute linear movements, which is why they are also known as linear drives. Rodless cylinders are primarily used in applications with longer travel distances, e.g. as a basic drive in a multi-axis gantry or for feeding tasks.
Pneumatic semi-rotary drives/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.
Tandem cylinders are two identical profile-barrel cylinders connected in series to double the thrust force in both directions of movement. A high-force cylinder is a cylinder design that is characterised by pneumatic compact cylinders connected in series. Pneumatic multi-position drives are available in a version that has two separate cylinders and in a version that has two to five cylinders connected in series.
Festo guided cylinders – drives with guide rods and linear guides – are pneumatic drives and are one of the "workhorses" of industrial automation. They are used in a wide range of applications such as lifting, pressing, pulling, pushing, clamping, stopping, holding, cutting, separating and much more. Both types of guided cylinders combine the benefits of linear movement with those of guided motion and stand out thanks to their extremely high stability.
With its feed separators, Festo provides handling technology solutions worldwide. Feed separators simplify the process of feeding in workpieces and are used whenever a continuous flow of workpieces has to be separated and transferred separately to a downstream device. Stopper cylinders are pneumatic cylinders that are used to stop movements, either with or without cushioning, in machines or workpiece carriers on transport systems. Stopper cylinders with cushioning can stop loads of up to approx. 800 kg on transport systems.
Clamping cylinders hold or clamp workpieces either directly with a pneumatically operated clamping element or through kinematics. The clamping element is swivelled out of the working area when it is inactive. They can realise very high holding forces with low energy input thanks to kinematics.
Bellows and diaphragm actuators with their special characteristics are in a class of their own in the world of pneumatics. For example, they have no stick-slip effect. They can be used as drive or pneumatic spring elements in a wide range of applications.
弹性缓冲器可吸收运动驱动器产生的能量。 驱动活塞的运动通过橡胶元件和/或液压方式实现减速停止。 在终端位置之前实施相对平缓的停止动作，可有效规避剧烈冲击及回弹效应，同时保护驱动器与机器部件，防止其出现磨损或不可逆的损坏。
气缸利用压缩空气对气缸活塞施加力，从而驱动活塞沿特定方向移动。 活塞所产生的运动通过活塞杆或摩擦连接传递至待驱动部件。 气缸是一种以压缩空气为工作介质的驱动器，通常最高工作压力为 12 bar，可输出直线或旋转运动。 气缸可分为单作用与双作用两种类型。单作用气缸仅在单一方向做功，双作用气缸在两个方向均可做功。
单作用气缸仅有一个压缩空气接口。 通入的压缩空气驱动活塞沿单一方向运动，气缸的作用力即在该运动方向上形成。 如果活塞需要返回初始位置，只需将气缸内的空气排出即可。 机械弹簧将活塞推回初始位置。 该部件设有通气孔或排气孔，以防止活塞在第二气缸腔室内运动时产生过压或负压。
优点：
缺点：
双作用气缸在每个运动方向上都需要压缩空气。 对于此类气缸，推进方向和返回方向的作用力均通过压缩空气产生。 控制双作用气缸，最简便的方法就是采用二位五通阀。

缺点：
先从基础入手。 使用我们的设计和选型工具，根据您所需的速度和力来确定气缸规格，同时有效控制耗气量。
然后即可在现场对运动进行微调。 添加流量/速度控制阀（节流阀）作为气缸速度控制器，可在无需重新设计机械结构的情况下使推进和返回速度更为稳定。
