CD85N20-25C-B Applications

A short 25 mm stroke with air cushioning suits high-cycle clamping, pressing, stamping and gripper actuation where impacts must be absorbed to protect tooling and reduce noise. The adjustable cushion at both ends allows 0.66 J of kinetic energy, so heavier fixtures can be run at speed without shock loading the end covers. The built-in magnet works with band-mounted auto switches for clamp-open and clamp-closed confirmation in the machine control sequence.
