For over forty years, PHD's foundation for our customers has been innovation, superior performance, quality, service, and value. From our humble beginnings in 1957, our founders Harry Sr., Jack, Tom, and Jim Neff along with Dick Futter and Dan Flickinger had a vision . . . . Manufacture a small bore cylinder that provides customers durability, reliability, strength, and rebuild ability for extended value. From this vision, PHD and the Tom Thumb® cylinder were created. Today PHD has grown into a worldwide corporation embracing new markets, and ways of designing and thinking about industrial automation.

Grippers
PHD's Grippers can be used for internal and external gripping and come in a variety of jaw styles to adapt to any application. Grippers range from miniature series to heavy duty series capable of more then 1600 pounds of grip force.

Multi-Motion Actuators
Multi-Motion Actuators provide rotary and linear motion from one output shaft. The reach-and-turn motions are independent from one another, making it easy to sequence the two motions. The Multi-Motion is ideal for part turnaround and orientation operations.
