CDUK20-25D Applications

The CDUK20-25D steps up to a 20 mm bore for higher output thrust while retaining the compact free mount body. Its non-rotating rod resists rotational load, making it suitable for driving small tooling, blades, wedges and locating pins where angular alignment matters. Typical uses include clamping, part ejection, gripper actuation, shuttle stops and lifting in packaging, food handling and general automation machinery. The built-in magnet supports auto switch end-position sensing.
