CD85N20-40C-B Applications

A 40 mm stroke with air cushion is a common workhorse for short-travel clamps, stops, kickers and blade or nozzle positioning on high-speed lines. Cushioning at both ends absorbs up to 0.66 J, protecting tooling and cutting noise where the cylinder cycles continuously. The ISO 6432 round body with basic clevis-style mounting fits standard mini-cylinder brackets, and band-mounted auto switches detect the built-in magnet to signal both end positions to the controller.
