Air Cylinder Centerline Mounts

The best support for a cylinder is along the centerline of the air cylinder. It is called CENTERLINE because the plane of mounting is the centerline of the cylinder.

This is a rigid support that requires accurate alignment.

Centerline mounts may utilize a FLANGE or EXTENDED TIE RODS.

Air Cylinder Selection

Here are some very important questions regarding the selection of the correct “type” of air cylinder for a specific application:

  • What is the required force output?
  • What is the required stroke length?
  • What is the load?
  • How will the cylinder be mounted?
  • What media will be used?
  • What is the temperature and substance exposure?

Air Cylinder Functions

Air cylinder functions are literally endless. Here are a couple examples of some common air cylinder applications.

  • Opening and closing the gate on a knife gate valve.
  • Allowing motion and movement in the animatronics industry.
  • Diverting goods on a conveyer system.
  • Raising and lowering rides at an amusement park.
  • Operating gates to rapidly unload a railcar commodity.
  • Press operation in the dry cleaning industry.
  • Brush movement in the auto wash industry.

The Perfect Air Cylinder

Air cylinders are offered in a variety of shapes, sizes, and types as well as with a multitude of standard options. At first glance, the number of permutations can be a bit overwhelming. The good news is that each cylinder type and configuration has a place in today’s motion-centric automation environment.

Air cylinders are selected by their ability to do work. To ensure maximum production, proper cylinder selection is vital. Cylinder application lives are often predestined long before the product is ever applied. The most common contributing factor that limits productivity is using an undersized cylinder.

Below are a couple of critical cylinder selection practices that should be considered when selecting the perfect air cylinders for the task at hand.

  • Determine the force
  • Subtract the piston rod area, if applicable
  • Know the true operating pressure
  • Allowance of internal actuator friction, i.e., seals, bushings, wears bands, etc.
  • Know the true load
  • Add speed requirements
  • Be sure to consider the angles
  • Design for slight future productivity requirement additions
  • Consider the kinetic energy
  • Test

These simple steps in the beginning will ensure that your air cylinder will keep your production levels at a pinnacle.
