Diaphragm air cylinders provide frictionless conversion of pneumatic pressure to linear force. Lack of stiction or blow-by ensures accuracy, repeatability, and sensitivity. They are available in strokes of 1.8 to 4.2 in. and are rated for pressures to 145 psi and temperatures of -75°to 400°F. ControlAir Inc., (603) 886-9400, www.controlair.com
