The new way to change

Ready to make a change for the better? Start with Quick Change Cylinder Locks, powerful positioning and locking devices designed to accelerate tool changeover and reduce down time. This smart time-saving alternative to bolts and dowels lets tooling align and lock in place instantly, insuring repeatable, uniform and precise installations. 

How does it work?
The Cylinder Lock is designed to receive and mate with a conical male knob. Positively locked in a static state, the Cylinder Lock actuates when air pressure is applied to release or receive the knob. The Cylinder Lock locates and positions the knob to within 0.0002″ with a holding force of 2,700 pounds.

A complete component family:

  • Choose from a wide array of cylinders and knobs to fit your quick change requirements.
  • Collars, air terminal boxes and plumbing kits make your installation or retrofit convenient.
