Contributed by Vicki Burt In a rodless air cylinder — also called a rodless slide — motion is transmitted through the body length by an internal piston moving with the cylinder, driven by compressed air. The piston is attached to a shuttle or carriage, which supports the load and moves it in a linear direction […]

DSNU-S standard ISO round cylinders are small, slim and light
The new DSNU-S round cylinder is the latest response from Festo to the need of machine designers for smaller versions of standard components so they can shrink the footprint of their machines or production lines accordingly. The DSNU-S, part of Festo’s core product range of always-in-stock components, is up to 40% slimmer, 35 mm shorter, […]
What are single-acting pneumatic cylinders?
Contributed by Frances Richards Pneumatic cylinders, also called air cylinders, pneumatic actuators, or pneumatic drives, are relatively simple mechanical devices that use the energy of compressed air and turn it into linear motion. Lightweight and low maintenance, pneumatic cylinders generally operate at lower speeds and less force than their hydraulic or electric counterparts, but are […]
How do you specify pneumatic cylinders?
Contributed by Darryl Powell, Doc’s Hydraulic-Pneumatic Training LLC When specifying pneumatic cylinders, you may think that the most important information needed is the bore size and stroke. While these details are certainly important, the application’s requirements are more critical. For example, several questions should be considered: is the cylinder in a wet environment (maybe salt […]
Application-specific pneumatic cylinder for cheese making
Festo recently introduced an application-specific pneumatic cylinder for cheese presses that improves consistency and quality in large operations and low-volume artisan cheese making. The stainless-steel outer body of the Festo CRD cylinder represents the latest in sanitary innovation as its unique bell-shaped construction provides best-in-class hygienic design. These cylinders are lubricated with NSF-H1 grease, which […]
How to improve compressed air systems
Here are some tips to reduce losses, right-size components and streamline circuits, all of which can lead to sizable cost savings. Phil McElroy, Product Sales Manager and IFPS-Certified Fluid Power Pneumatic Specialist, Norgren Most industrial facilities depend on compressed air for a range of operations, performed by everything from simple air tools to far-more-complicated pneumatic […]
Functional safety with pneumatic rod locks
Functional safety features in pneumatic machines and systems are critical in reducing the risk of injury without impacting operational efficiency and productivity. Designers of functionally safe pneumatic systems have put in fail-safe mechanisms to detect potentially dangerous conditions and to activate a protective or corrective device, such as a pneumatic rod lock, that will prevent […]
D2-series NFPA tie rods added to NITRA air cylinders from AutomationDirect
The NITRA pneumatic product line now includes the D2-Series double-acting, NFPA heavy-duty tie rod air cylinders ideal for use where abusive conditions exist. These pneumatic air cylinders have a 250 psi operating pressure and are interchangeable with other popular brands. New models are available with and without adjustable cushions to provide end-of-stroke deceleration at both […]
How can you achieve cylinder flow reduction?
Looking for ways to further reduce your compressed air demand? Consider investigating air cylinder actuation. Often times, air cylinders in production machinery only require significant force during a single power stroke, but still use full line pressure to return the cylinder to resting position. Let’s compare the air consumption for double acting versus a spring […]
Rodless cylinder solutions for compact pneumatic linear motion
Designers requiring linear motion should consider rodless cylinders to realize compact packaging and other benefits for pneumatic actuation, without the cost of electrically-driven options. Contributed by Kevin Kakascik, Technical Marketing Engineer, AutomationDirect Machine and equipment automation projects — whether performed by an original equipment manufacturer (OEM), a systems integrator (SI), or the capital projects group at […]
