This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X70, 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 ACPD20X70
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X70 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm 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 ACED20X70 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X70
A double acting compact cylinder with a rod through both covers, the ACPD20X70 delivers 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa), because both strokes work on the rod-side area. The 20 mm bore carries a 10 mm rod with an M6x1.0 female thread, and the M5x0.8 port follows the bore. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding.
The through-rod resists rotation and side load and gives a symmetric mount, while the rear rod can carry a sensor flag. Fixed TPU bumpers sit at both ends and the speed range is 30-500 mm/s. Note this model is discontinued: the current-production direct is ACED20X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X70 (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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACPD20X70 Is Used
Light part clamping in CNC fixtures
The 117.8 N per side at 0.5 MPa holds small aluminium or plastic workpieces in milling jigs, with the through-rod keeping the clamp aligned under side load.
Flag-driven position sensing on test rigs
The rear rod carries a flag past a CMSE or DMSE switch (when the -S magnet is ordered), giving end-of-stroke confirmation on a 70 mm test stroke.
Push-pull transfer in compact modules
Equal force both directions makes the cylinder ideal for short reciprocating slides in packaging and electronics assembly machines where space is tight.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X70 with the ACED20X70
At 117.8 N per side, this 20 mm bore suits light clamping and positioning; drop to the 16 mm bore (75.4 N) for smaller loads or step up to the 25 mm bore (206.2 N) when more force is needed. The 70 mm stroke sits inside the 100 mm standard for this bore, so no made-to-order build is required. If the load must stay put when air is lost, add a rod lock or pilot check - the cylinder itself will drift. Choose the -S code if you need the optional magnet for CMSE / DMSE switches; without it no sensor can be fitted. For new designs, order the ACED20X70 instead.
Replacement checklist
- ✓ Current-production ACE → ACED20X70
- ✓ 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 ACPD20X70 FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8.
Order ACED20X70, the ISO 21287 successor made by swapping the P for an E. It matches the same 20 mm bore, 70 mm stroke and force class, and accepts the FA/FB flange, LB foot and CA/CB clevis mounting family. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to a DIN-standard pattern.
