The Marsh Bellofram Small Bore Diaphragm Air Cylinders are in reality, actuators that are constructed from elastomers, engineered metals and also fabrics. They need no lubrication at all and are entirely economical and without friction issues. Their applications will include lifting, clamping, pushing, coining, turning and alternative linear force or even actuation motions in several operations.
Moreover, the event of the long stroke rolling diaphragm for dynamic sealing off has been field-proven to be a reliable solution for several applications that are in need of low friction, no lubrication, less leakage and wider temperature variations apart from a low ownership cost in totality. The rolling diaphragm is very popular as a means of sealing and this led to many requests to come up with a standard line of off the shelf diaphragm cylinders, that are single and double acting; having short and long stroke with the capacity for wide selection of effective areas.
