This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X70B, 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 ACPD12X70B
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X70B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X70B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X70B
Double acting with a rod leaving both covers, the ACPD12X70B is a DIN-standard compact cylinder in the discontinued ACPD family. Because each stroke works on the rod-side area, output is identical in either direction: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa. The 70 mm stroke is beyond the 50 mm standard limit for a 12 mm bore, so it is a made-to-order build. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped slides and small fixtures.
The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag on a moving table. A fixed TPU bumper sits at each end to soften end-of-stroke contact. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it covers 30-500 mm/s between -20 and +70 C. This model is discontinued; the current-production direct is ACED12X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X70B (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 ACPD12X70B Is Used
Lab sample pusher
The 42.4 N through-rod advances microscope slides or test vials between stations on a compact benchtop analyzer where a full-length body would not fit.
Flag trigger on a small slide
The rear rod carries a sensor flag to trip a proximity switch on a 70 mm indexing slide, giving position feedback without extra hardware.
Micro-assembly eject
About 25 N of usable force at 0.5 MPa ejects finished connectors or pins from a light-duty jig, with equal force on the return stroke.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X70B with the ACED12X70B
At 12 mm bore you are at the bottom of the range: 42.4 N at 0.5 MPa both ways. If the load needs more, step up to bore 16 for 75.4 N or bore 20 for 117.8 N at the same pressure; if it needs less travel force, nothing smaller exists in this series. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. This version has a male rod thread (B code) and no magnet, so CMSE or DMSE switches cannot be fitted - order the -S variant if position sensing matters. For new projects, specify the ACED12X70 instead.
Replacement checklist
- ✓ Current-production ACE → ACED12X70B
- ✓ 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 ACPD12X70B FAQ
It is a double-rod cylinder, so force is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a peak of 8.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 70 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
Only if the cylinder carries the optional -S magnet code; this ACPD12X70B has no magnet, so CMSE or DMSE switches cannot be mounted on it. The ACPD family is discontinued - order the ACED12X70, the ISO 21287 successor in the same bore, stroke and force class, and confirm its mounting dimensions before the swap.
