Super Air Cylinders

Marsh Bellofram diaphragm Super Air Cylinders are actuators made from elastomers, engineered metals and fabrics. They require no lubrication and are virtually frictionless and economical. Air cylinders can be used to provide lifting, clamping, pushing, coining, turning and other linear force or actuation motions in many applications.

Development of the long stroke rolling diaphragm for dynamic sealing has been field-proven as a reliable solution for many applications requiring low friction, no lubrication, low leakage, wide temperature variations and low total cost of ownership. The popularity of the rolling diaphragm as a sealing means led to many requests for a standard line of “off the shelf” diaphragm cylinders; single and double acting, short and long stroke with a wide selection of effective areas. To meet these requests, the long stroke rolling diaphragm cylinder was developed; Marsh Bellofram has supplied many thousands of them since their 1965 introduction.  Super Cylinders are available only in spring-return varieties and in Series F stroke variations. All mounting options offered on standard cylinders are also available on super cylinders.
