This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X70, 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 ACPD12X70
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X70 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 ACED12X70 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X70
The ACPD12X70 is a double acting, double-rod compact cylinder in AirTAC's DIN-standard ACP series: a 6 mm rod exits both covers, so the 12 mm bore delivers the same 42.4 N at 0.5 MPa on every stroke, in either direction. Its 70 mm stroke is a non-standard, made-to-order length because bore 12 tops out at 50 mm as a standard stroke. The hard-anodized aluminium body and S45C hard-chrome rod run on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with speeds of 30-500 mm/s.
Because the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this unit slips into tight pick heads, test fixtures and sliding gates where a full-length body cannot. The through-rod resists rotation and side load and gives a symmetric mount, while the back-end rod can carry a sensor flag. A fixed TPU bumper sits at both ends. Note: 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 ACED12X70 (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 ACPD12X70 Is Used
Lab slide comparator
The symmetric through-rod carries a comparator probe on the front rod and a sensor flag on the rear rod, with 42.4 N per side at 0.5 MPa cycling a 70 mm made-to-order stroke at up to 500 mm/s.
Bottle reject pusher
On a bottling line, the equal 42.4 N in both directions lets one valve push an undersized bottle off the conveyor and retract with identical force, and the short body fits the narrow guard channel.
PCB test fixture actuator
The 12 mm bore's light 42.4 N press at 0.5 MPa seats test pogo-pin boards gently, and the M5x0.8 ports keep the manifold footprint minimal inside the fixture frame.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X70 with the ACED12X70
If you need more, the 16 mm bore gives 75.4 N both ways at 0.5 MPa; if 42.4 N is already generous, there is no smaller ACPD bore. Position is not held when air is lost - the piston drifts - so add a rod lock or pilot check for a held load. The 70 mm stroke is made to order (standard for bore 12 is 50 mm). This model is discontinued; order the ACED12X70 as the current replacement and verify the ISO 21287 mounting footprint. For position sensing, the optional -S magnet code enables CMSE / DMSE switches - without -S there is no magnet.
Replacement checklist
- ✓ Current-production ACE → ACED12X70
- ✓ 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 ACPD12X70 FAQ
No - 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 per direction (rod-side area on both strokes). At 1.0 MPa the bore reaches about 8.6 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s.
Correct: bore 12 has a 50 mm maximum standard stroke, so 70 mm is a non-standard, made-to-order length. Also confirm the female M3x0.5 rod thread and PT ports suit your fittings, decide whether you need the optional -S magnet (without it no CMSE / DMSE switch can be mounted), and note the model is discontinued - the ACED12X70 is the current direct, so check the ISO 21287 mounting dimensions against your fixture before swapping.
