NFPA Cylinder 4 in. Bore 2 In. Stroke

Product #:81.902

    Description

    This NFPA-compliant pneumatic cylinder is designed for industrial compressed air systems. Made of corrosion-resistant aluminum, it provides excellent durability and features adjustable cushions at both ends, ensuring smooth and quiet operation.
    The output force of the cylinder depends on the effective piston area and the applied air pressure. The forces differ in extension and retraction, as the rod reduces the active surface area during the return stroke. This design ensures precise control, consistent power, and optimal efficiency in industrial pneumatic applications.

    More Information

    Selecting the proper cylinder for the application remains the responsibility of the system designer; these forces should be used as a guideline and it is important to do the required tests according to the specific application. TOPRING pneumatic cylinders are intended for use in industrial compressed air systems only. They must not be used where pressure or temperature may exceed maximum rated operating conditions (see specifications). In lubricated applications, some oil mist may escape from the point of use into the surrounding atmosphere.
