This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X25SB, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPD Double Rod Compact Cylinder ACPD12X25SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X25SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X25SB
This ACPD12X25SB is a double acting compact cylinder with a rod leaving both covers, so the 12 mm bore delivers the same 42.4 N at 0.5 MPa on every stroke - the through-rod sees rod-side area on both faces. The male rod thread (B code) and 25 mm stroke suit small pick-and-place heads, and the optional -S magnet this model carries lets CMSE / DMSE switches report position. Note the family is discontinued; the current-production direct is ACED12X25.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside tight fixtures and guarding. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries M5x08 ports - actually M5x0.8 - and speed runs 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X25SB (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD12X25SB Is Used
Micro part ejection
The equal 42.4 N thrust in both directions ejects small stamped terminals from a die on the forward stroke and retracts the pusher with identical force, no spring return needed.
Gated sensor flag carriage
With the -S magnet and CMSE switches on a 25 mm travel, the through-rod carries a flag past two reed switches to confirm gate open and closed on a packaging line.
Symmetric slide tensioning
A rod on each cover lets a light conveyor tensioning arm pull from either end with the same 59.4 N at 0.7 MPa, keeping belt tension identical in both directions.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X25SB with the ACED12X25SB
At 42.4 N per direction this bore sits below the 16 mm size (75.4 N at 0.5 MPa) and above nothing smaller in the range, so step up to 16 mm if your part weight approaches 4 kg equivalent. The 25 mm stroke is well inside the 50 mm standard maximum for bore 12; longer strokes are made to order. With the -S magnet fitted, add CMSE or DMSE switches for end-of-stroke sensing. Since ACPD is discontinued, order ACED12X25 as the replacement and confirm ISO 21287 mounting dimensions before the swap - the ACP follows DIN-standard holes.
Replacement checklist
- ✓ Current-production ACE → ACED12X25SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD12X25SB FAQ
Because a rod exits both covers, force is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum of 8.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, and the 12 mm bore uses M5x0.8 ports with a 6 mm rod.
Order ACED12X25, the ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 25 mm stroke and force class in a current-production short body. Confirm the ISO 21287 mounting dimensions first, since the ACP series was built to DIN-standard fixing patterns.
