Festo piston rod cylinders are pneumatic drives for executing linear movements. They are available as round cylinders, profile cylinders, compact cylinders, short-stroke cylinders, flat cylinders, miniature cylinders, screw-in or stainless-steel cylinders; and, depending on the piston diameter, they can provide thrust forces of up to 50 kN at 6 bar. Selected types in accordance with the ATEX directive are also suitable for explosive atmospheres or are made of corrosion-resistant stainless steel and therefore particularly easy to clean.

Thanks to their round design, round cylinders can even be installed in tight spaces. What all round cylinders have in common is excellent operational performance, a long service life, and quick and easy installation. The piston rod cylinders are available both as double-acting and single-acting actuators, as well as pneumatic cylinders according to standard ISO 6432.
Profile cylinders and tie rod cylinders have identical mounting interfaces and the same technical data, and both have dimensions that conform to the ISO 15552 standard. However, these linear drives differ above all in how the cylinder sensors are mounted: they are securely inserted in the slot on the profile tube, while on cylinders with tie rods the cylinder sensors are attached to a tie rod using a separate mounting kit.
Compact cylinders are pneumatic cylinders with an installation length that is extremely compact in relation to the stroke length. They are typically used when space is extremely limited and the requirements for lateral loads are low. The compact cylinders belong to the group of directly mounted cylinders and are usually installed without any specific mounting accessories. Short-stroke cylinders start from a stroke of 2.5 mm and flat cylinders are characterised – as the name suggests – by a particularly flat design with an oval piston that is protected against rotation.

多位置气缸是一种只需几个螺丝而无需借助其它附件（螺钉除外）就能直接从多个方位进行安装的气缸。插装式气缸可以通过螺纹孔直接安装在系统中，并且可以作为单作用气缸工作。无需单独的附件即可安装这些活塞杆气缸和连接气源。因此布局非常节省空间。
这些是活塞杆气缸，带有用于夹紧活塞杆的附加夹紧单元。当工作压力低于最小值时，摩擦夹紧机构会激活，并且根据类型，可能有间隙或没有间隙。带有夹紧机构的气缸用于静态夹持。动态制动和安全相关控制系统的使用需要具有相关测试证书的刹车。
不锈钢气缸的特点是即使在腐蚀性环境中也具有耐腐蚀性。这尤其要归功于这款气缸使用的优质不锈钢 1.4301 和 1.4401。已经过实践检验的高合金不锈钢类型可避免清洁剂和消毒剂可能造成的化学应力和损坏。
活塞杆气缸总是有一个带有驱动活塞的活塞杆，其运动由压缩空气控制。施加到活塞上的能量然后通过活塞杆传递到要移动的部件上。带活塞杆的气缸有双作用和单作用活塞杆气缸。
带活塞杆的单作用气缸只有一个气源口。通过气源口向气缸供应压缩空气，使活塞沿一个方向移动。当气缸再次释放空气时，活塞在弹簧作用下返回至初始位置。
另一方面，双作用气缸有两个气源口，仅采用压缩空气驱动。当压缩空气供应到任一气源口时，它会导致气缸伸出和缩回。
