The Bimba FOR-041-M Reverse-Acting Spring Extend Cylinder is a compact pneumatic actuator with a 3/4-inch bore and a 1-inch stroke. In spring-extend (reverse-acting) operation the rod is extended by an internal return spring when air pressure is removed, while applied air retracts the rod for controlled positioning. The model designation FOR-041-M identifies this reverse-acting, spring-extend variant within Bimba's cylinder lineup.
