By Frances Richards, contributor Pneumatic cylinders are a clean and cost-effective option for achieving reliable linear motion in many industrial environments. Because they are lighter weight and lower maintenance than their hydraulic and electric counterparts, they are an excellent choice in applications from factory automation and transportation to packaging and life sciences. Two main styles […]

How do you mount/install a compact pneumatic cylinder?
By Vicki Burt, Contributor One of the benefits in choosing a compact cylinder is getting effective motion in a small footprint. These short-stroke, low-profile, air cylinders are designed to fit into tight spaces and are available in a variety of mounting options. Pancake cylinders are a trademarked line of compact air cylinders from Fabco-Air Inc. […]
How do pneumatic rodless cylinders/slides work?
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 […]
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 […]
Cutting compressed-air costs at the point of use
Energy efficiency has become a hot topic. There are worldwide initiatives to rein in CO2 emissions and limit climate change. Consumers are becoming critical and demand products that are produced in a sustainable way. Furthermore, many production plants are more aware of the huge cost reductions involved with energy savings. As a result, firms are […]
How to turn data into useful information
In a preview of their offerings at this year’s digital Hannover Fair, scheduled for April 12 to 16, Emerson takes a pragmatic look at today’s IoT landscape and discusses a number of new edge computing and analytics products that help manufacturers turn data into actionable insights. “We are 30 years into the concept of ‘big […]
What is a pneumatic muffler?
Pneumatic mufflers, also called silencers, safely and quietly vent pressurized air to atmosphere. They are commonly installed on air valves, cylinders, manifolds and fittings. Without a muffler, air exhausting from many types of pneumatic-powered equipment can be so loud as to be detrimental to the surrounding environment and potentially harm workers. Noise results when fast-moving, […]
What is a conical screw compressor?
A conical screw compressor is an offshoot of the conventional screw compressor. In a typical screw compressor, two meshing helical screws or rotors are mounted side-by-side in a housing. The rotors spin in opposite directions and draw air into the cavities between them. Volume decreases as air progresses along the rotors and compresses air, which […]
What is a scroll compressor?
Scroll compressors are positive-displacement devices that work by internal compression. Air (or other gas) is drawn in, trapped, reduced in volume and, finally, discharged at the outlet port. The concept of a scroll compressor has been around for more than a century, but it took more-recent advances in manufacturing technology to make the product viable. […]
