CD85N25-25-B Applications
A short-stroke ISO 6432 actuator for clamping, indexing, stopping and gate applications where travel is limited but a full 25 mm bore output is needed. 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 motion. The unique C85 rod packing design resists dust ingress, suiting extremely dusty environments such as woodworking, textile and foundry lines.
