Pneumatic Cylinders and Their Types

Pneumatic cylinders are a type of mechanical appliance that makes use of power generated from compressed gas to create a force in reciprocating linear motion. They are also sometimes referred to as air cylinders, as in “pneuma” meaning air. Much like in hydraulic cylinders, a force is exerted into the piston which propels it towards the desired direction. In these devices, the piston is actually a cylinder or a disc, and the force developed by it is transferred by the piston rod to the object that is to be moved. Pneumatics is occasionally preferred by some engineers as they are much cleaner, quieter and doesn’t require much space for the storage of fluids.

Depending on the purpose for which they are used, these cylinders come in a variety of shapes and sizes. This is also applicable to the kind of material used to construct these cylinders. They can be made out of steel, stainless steel, aluminum and nickel-plated brass. Choice of materials is mostly dictated by the humidity, temperature, specific stroke length and the amount of loads. The body constructions in which these cylinders are available include the following:

  • Flanged-type cylinders: In this type, fixed flanges are present at the ends of the cylinder.
  • Tie rod cylinders: This is the most common form of cylinder construction and can be used for a wide variety of loads. It has also been proven as the safest form to work with.
  • Threaded end cylinders: In this type, the ends are screwed to the tube body. However, reduced material may lead to weakening of the tube and introduce thread concentricity issues to the system.
  • One-piece welded cylinders: In this type, the ends are crimped or welded to the tube. Although these are inexpensive, they make a cylinder non-serviceable.

There are different types of pneumatic cylinders in use in a wide variety of industrial and commercial arenas. Some of them have been discussed below in brief.

Single-acting cylinders

Single-acting cylinders or SAC makes use of pressure that results from compressed air to create a unidirectional driving force, usually towards the outside, and a springing motion to get back to its original position. In most cases, these cylinders have very limited extension because of the space taken up by the compressed spring. Another flip side of single-acting cylinders is that a portion of the force is always lost as it attempts to push itself against the spring.

Double-acting cylinders

Double-acting cylinders or DAC makes use of air pressure to move in extend as well as retract strokes. These cylinders are comprised of two ports which lets the air in; one for instroke and the other one for outstroke. The stroke length for double-acting cylinders is not limited. This type of cylinder is not however without its flaws. The piston rod may buckle and bend over time and precise calculations should be carried out before working with these cylinders.

Telescoping cylinders

Telescoping cylinders or telescopic cylinders come in either single-acting modes or double-acting modes. It makes use of a piston rod that is placed within a few hollow stages of ascending diameters. Once activated, the piston rod along with each of the successive stages “telescopes” out like a separate segmented piston. This type of pneumatic cylinder design allows for much longer strokes than what can be achieved by a single-stage cylinder of same retracted or collapsed length. However, its segmented piston design increases the chances for piston flexion. For this reason, these type of telescoping cylinders are mainly reserved for applications where its piston has to go through minimal side loading.

Points to Consider when Buying an Air Impact Wrench

Have there ever been times and instances where you, or your family member had to build, construct, or even repair something around your home or office, or even do some work on your car, but you just did not have the right and appropriate tools to get the job done? Do you still use a normal, manual winding wrench to loosen or tighten those loose nuts and bolts?

 

With the power and science of modern technology nowadays, you, your family members, or even your fellow work-mates need not trouble yourselves with the manual and tedious labor of winding wrenches, for there is the air impact wrench! The air impact wrench is also known as an air wrench, air gun, torque gun, or windy gun.

 

This automated power tool brings high torque productivity while applying the least amount of effort by the user. This is done by accumulating energy in a rotating collection, then abruptly and rapidly distributing to the output shaft.

 

There are some points to consider however, when using, and more importantly, buying an air impact wrench. Probably the most touched upon issue and concern when purchasing an air wrench is whether or not the impact wrench you are getting, is the not only suitable to your specific needs, but also for the optimal output of the tool in general.

 

The best and most effective way to get the best impact wrench possible is by checking the brands and models of these wrenches.

 

Some of the most reliable brands out there are Milwaukee, which offer some of the strongest air impact wrenches out in the market, and Ingersoll-Rand, which provide not only some of the sturdiest wrenches, but also offer most power tools that are both efficient and reliable.

 

Another is Chicago Pneumatic which specializes in designing and manufacturing heavy-duty impact wrenches, much like Milwaukee.

 

Aircat is another brand and model of one of the best air impact wrenches which provide really high quality wrenches, and other such power tools for home or garage use.

 

Some other concerns and matters to consider before buying an are:

 

  • Checking how much torque the air wrench contains
  • The manufacturing and design of the wrench
  • Accumulated and total weight of the wrench itself
  • Air compressor size
  • Size drive of the air wrench
  • Budget to purchase the actual wrench

 

These points, though seemingly common and surely considered before purchasing the actual air wrench by the prospective consumers, are some of the most essential issues which are overlooked by the buyers themselves. Taking these points into consideration when looking to buy an air wrench will help you to make the right choice.

 

Buying the best wrench for your needs will undoubtedly save you not only time, or money, but ultimately you will have the satisfaction of having purchased the best tool out there for you. Be sure to keep these tips in mind, and you will definitely and certainly become the proud owner of an air impact wrench that will get the job done.

Air Sanders: Forget Electric, Go Air!

An air sander is a common air tool often overlooked by most people. If you already have an air compressor to run your impact wrench, you may consider purchasing an air sander instead of an electric model. Your average off the shelf electric sander is fine for little home projects. But if you are really concerned about production and speed, an air sander will blow it away. These tools are also more rugged, versatile and lighter.

The main reason is the power source is your air compressor, not the little electric motor in the sander. This also makes them easier to fit into weird places and hold over your head to reach a ceiling. At the end of the day, an air sander is much kinder to your hands, while delivering more power. They also come in models that are both sanders and buffers. I really recommend one of these if you are a car or boat enthusiast. An air buffer will make quick work of a long wax job on your favorite ski boat. You can then turn around and use the same tool to sand down your kitchen cabinets for painting.

Air sanders are really versatile tools and a great addition to your air tools for your garage compressor. There are also orbital sanders, dual action sanders and palm grip sanders for any application you might run across. It may be time to take a second look at that air compressor stuffed in the garage. They can do a lot more than just fill up tires and run impact wrenches.
