Q: Is there a way of firmly holding piston rods with an air powered device?

A: Use an air locking collet fixture. The device operates just like a single acting cylinder; air to close or open, spring to reverse.

Air to close is an active locking unit.

Air to open is a passive locking unit.

The locking collet fixture fits onto the front nose of the cylinder over the piston rod.

They are used to hold the cylinder safely usually during an emergency shut down or, especially in the case of the passive lock, an air failure to the system.

Q: How do I prevent the tooling attached to my air press rod from turning?

A: Order the press cylinder with a non-rotating rod option.  This can be a cylinder with flats on the piston rod or an external guide attached to the piston rod.

Q: Is it possible to build an air circuit using components that do not require lubrication?

A: Most cylinders and valves are available with non-lube seals.

Q: I have an application in a high temperature environment. What should I do to avoid complication?

A: The control valve powering the cylinder should be mounted as far away from the heat as possible. While temperatures exceeding 100^oC can cause breakdown in Buna N seals, most cylinders may be supplied with fluorocarbon seals instead of Buna N. Fluorocarbon seals are effective to 204^oC. Fluorocarbon seals are also known as Viton seals.

Q: How may I minimize the adverse effects of cylinder side loading?

A:

1. Be sure that the object being moved is in exact alignment with the piston rod. If the cylinder is rigidly mounted and the rod is forced off line, the cylinder bearing will wear prematurely and a loss of power will occur. It may be helpful to use guide rails to keep the object being moved in proper alignment.
2. Don’t use all of the stroke. Particularly on pivot and clevis models, it is wise to have the piston stop a few inches short of full stroke. This makes the cylinder more rigid and extends bearing life.
3. Order your cylinder with an external bearing. An external bearing takes advantage of physics by providing more bearing surface and a longer lever point than a standard cylinder type.
4. Order a Self-Aligning Rod Coupler.
