Air cylinders are widely used for applications requiring rapid, repetitive motion. They excel at doing this because their reliable, long-life operation does not generate heat. What air cylinders are not so good at is moving a load at low speed or reacting to subtle changes in pressure without producing jerky, erratic motion.That may be the case with conventional cylinders, but rolling-diaphragm cylinders eliminate the need for a dynamic piston seal, which is the main source of erratic operation in conventional air cylinders.Download this guide and review Basics of Diaphragm Cylinders: Virtually Frictionless and Leak-Free, sponsored by ControlAir who makes your entire process run smoother.
