A recess at the piston mating surface allows the air to work on a larger effective piston area for faster breakaway. The longer bronze rod bushing provides a maximum load bearing ...

The large rods reduce the effective area of the piston on the rod end resulting in smaller retraction ... This maximum speed is determined by cylinder size, port size, air pressure, bore and length of ...

These were turned from a scrap of aluminum rod and an old flange-head bolt; when air pressure is applied, the bolt is drawn into the cylinder, which locks the arm in place. To make it easy to ...
