Pneumatic cylinders, which are also known as air cylinders, are mechanical devices that use compressed gas as their source of power in producing a force in a reciprocating linear motion. The use of pneumatic cylinders in certain applications is very much recommended by engineers since they are quieter, cleaner, and do not require huge space for fluid storage.
The most standard components of pneumatic cylinders are cap-end port, tie rod, rod-end port, piston, barrel, and piston rod.
Categories of Pneumatic Cylinders
There are two types of pneumatic cylinders: single-acting and double-acting.
In a single-acting cylinder, the air is solely supplied to one side of the piston, which moves the piston in only one direction. Alternatively, the movement of the piston in the opposite direction is pushed by a mechanical spring. The designs available for this type of cylinder are to be with either base position minus (spring return) or base position plus (spring extend), which all depends on whether the compressed air will perform the outstroke or the in-stroke respectively.
For double-acting cylinders, the cylinder barrel is fastened with a head cap on one end and an end cap on another. A piston drives the rod in a linear direction. And when the compressed air enters through the cap-end port, the piston moves away from the end cap and then pushes the rod out. Alternatively, when the compressed air enters through the rod-end port, the rod is pushed back to the negative position. The piston movement on this cylinder depends on the air pressure on the inside.
A single-acting cylinder has the advantage of returning the piston to a base position. A double-acting cylinder, on the other hand, is its longer strokes and constant output force through a full stroke. It also has better control and can operate at higher cycling rates.
Pneumatic Cylinders from Parker
Parker has been contributing to the innovation of systems and technologies for more than a century now. The company has seen challenges and victories that all its employees have worked hard for. From pneumatic brake systems to other related parts and components, the company is very much suitable to design and engineer pneumatic cylinders that are being sold in the market today.
Parker pneumatic cylinders are constructed of high-quality, corrosion-resistant materials and are available in a wide variety of sizes, strokes, and diameters. Parker also boasts significant parts and kits available for their pneumatic cylinders, which offer unparalleled reliability and performance. The styles available for Parker pneumatic cylinders include standard and compact air cylinders, aluminium cylinders, guided cylinders, NFPA and ISO pneumatic cylinders, low profile pneumatic cylinders, rod pneumatic cylinders, and stainless steel air cylinders.
Parker Pneumatic Cylinders at Work
The work principles of Parker pneumatic cylinders hugely depend on the type of cylinder. For instance, their P1P Series, which are classified under single-acting cylinders, is normally used for applications where tasks are only done in one direction. Some examples of P1P Series applications include clamping, positioning, marking, stroking, and light assembly applications.
Alternatively, the P1F Series from Parker belongs to the double-acting cylinder category, which accounts for almost 95% of all cylinders used in pneumatic control circuits. This type of cylinders is typically used in applications where the thrusts and stroke lengths required are excessive of those available from single-acting cylinders.
