PHD Tom Thumb NAGMN113/8X2 Pneumatic Tie Rod Air Cylinder 420271-01

This is a PHD Tom Thumb cylinder built by PHD, Inc. of Fort Wayne, Indiana. The label carries model NAGMN 1-1/8 X 2 (the second letter is partly obscured and may read H) and code 420271-01 606. In PHD's ordering system the final figures give bore and stroke, so this unit has a 1-1/8 inch bore and a 2 inch stroke.

Tom Thumb cylinders are compact tie rod actuators for light automation work: clamping, pressing, ejecting, positioning and short transfer motions on assembly machines, fixtures and packaging equipment. PHD builds the line in 3/4, 1 and 1-1/8 inch bores, as air cylinders rated 20 to 150 psi and as Series HV hydraulic cylinders rated 40 to 1500 psi for non-shock service. The current catalog lists a 3/8 inch rod with 3/8-24 thread as standard on the 1-1/8 inch bore, and the line is described as field repairable.

Because the service letter on this label is not clearly legible, buyers replacing an existing cylinder should match the full model code, mounting style and rod end to their machine before ordering. Machine builders, maintenance departments and automation integrators are the usual users of this part.

Available from King Surplus inventory in Del Rio, Texas.
