This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X70S, 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 ACPD12X70S
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X70S 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 ACED12X70S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X70S
A double acting, double-rod compact cylinder, the ACPD12X70S pushes a 12 mm piston through a 70 mm stroke with a rod leaving both covers, so the output force is identical in each direction: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa. Because both strokes work on the rod-side area, you never have to derate the return stroke. The through-rod also resists rotation and light side load, and the free back-end rod is a handy place to carry a sensor flag. Note that the 70 mm stroke is longer than the 50 mm standard maximum for this bore, so it is a made-to-order build.
The hard-anodized aluminium body with an S45C hard-chrome rod runs at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, and -20 to +70 C, with a fixed TPU bumper at each end. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and tight fixture plates. This model is discontinued; the current-production direct is the ACED12X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X70S (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 ACPD12X70S Is Used
Micro part ejection
The 42.4 N through-rod nudges small stamped terminals off a die face in both directions, with the 70 mm made-to-order stroke clearing the full nest width.
Flag-driven position sensing
With the -S magnet fitted, a CMSE switch on the barrel and a flag on the rear rod confirm end positions on a compact lab automation slide.
Symmetric test fixture clamp
Equal 59.4 N force at 0.7 MPa from either rod end lets a PCB test fixture clamp and release with the same pressure, mounted through LB feet in a tight frame.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X70S with the ACED12X70S
At 42.4 N per side at 0.5 MPa this bore suits light gripper and gate jobs; step down is not available (12 mm is the smallest bore), while the 16 mm ACPD16X70S gives 75.4 N if you need more. The piston drifts when air is lost, so add a rod lock or pilot check for a held load. The S code here means the magnet is fitted, so CMSE or DMSE switches mount directly; the ACED12X70 is the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED12X70S
- ✓ 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 ACPD12X70S 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 on each stroke, with a peak of about 8.6 kgf at 1.0 MPa. The 70 mm stroke exceeds the 50 mm standard maximum for bore 12, so it is built to order. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed or solid-state switches can be clamped to the barrel. Each end carries a fixed TPU bumper that only softens end-of-travel contact. The ACPD line is discontinued; the ACED12X70 is the current ISO 21287 direct, so verify mounting dimensions before ordering.
