CD85N25-250-B Applications
A long-stroke ISO 6432 actuator for pushing, ejecting and transfer moves that need extended travel from a compact round body. The built-in magnet allows auto switches to sense piston position without external limit switches. Rubber bumpers absorb end-of-stroke impact for general-purpose, moderate-speed motion. The unique C85 rod packing design resists dust ingress, suiting extremely dusty environments such as woodworking, textile and foundry lines.
