CD85N12-125C-B Applications
A long-stroke ISO 6432 round-body actuator for transfer and handling equipment. The air cushion absorbs end-of-stroke impact to reduce shock and noise at higher speeds, and the built-in magnet allows auto switches for position sensing. Suited to feeding, pushing and positioning on automated lines where a 12 mm bore delivers the needed force over an extended stroke.
