Why the double rod version
With a rod supported at both ends, the piston cannot twist under an off-centre load, so a separate guide is often unnecessary. The second rod gives a mounting point for a sensor dog or a stop, and the equal areas on both sides mean the same force and speed in each direction — useful where a clamp must release with the same force it applies.
Short stroke, large bore
A ø40 bore at 25 mm stroke delivers high thrust in a body barely longer than the bore, which suits pressing and clamping where the part only has to move a few millimetres but must be held firmly.
About the CQ2 Z series

- Double clevis brackets and a compact foot bracket are available
- Magnet-equipped versions carry the CDQ2W prefix
Ordering
Order by the full code CQ2WB40-25DZ. The W marks the double rod body, then bore, stroke and mounting letter — a single character changes the part. This code has no built-in magnet; for auto switch mounting order the CDQ2W equivalent. The ø20 size (CQ2WA20-20D) is also available.
