This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X40B, 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 ACPD12X40B
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X40B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X40B
Double acting with a rod leaving both covers, the ACPD12X40B pushes and pulls with identical output: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The 12 mm bore drives a 6 mm through-rod with a male thread (the B code) on each end, and the 40 mm stroke sits inside the 50 mm maximum standard stroke for this bore. Note this model is discontinued; the current-production replacement is the ACED12X40, so confirm ISO 21287 mounting dimensions before swapping.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim pick-and-place heads and small test fixtures. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at each end, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). The magnet is not fitted here; order the -S code if you later need CMSE or DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X40B (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 ACPD12X40B Is Used
Micro part ejection
The symmetric 42.4 N push and pull nudges small stamped or molded parts off a nest in a compact assembly head, with the 40 mm stroke clearing the part in tight quarters.
Lab slide actuation
A benchtop test rig can drive a 2 kg sample tray between two positions at 30-500 mm/s, using the rear rod as a position-flag carrier for a nearby switch when the -S magnet is ordered.
Small valve toggling
The through-rod resists rotation while its male thread picks up a clevis or knuckle, letting a compact fixture flip a light lever or gate with equal force either way.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X40B with the ACED12X40B
At 42.4 N per direction this is the lightest ACPD force class, so step up to the 16 mm bore (75.4 N at 0.5 MPa) if your part or jig weighs more, or stay here for tiny slides and gate nudges. Because a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check if the load must stay put. The male rod thread (B) suits couplers and knuckles; FA/FB flange or LB foot mounts bolt to the same face. This unit is discontinued - specify the ACED12X40 as the direct successor and verify the ISO 21287 footprint.
Replacement checklist
- ✓ Current-production ACE → ACED12X40B
- ✓ 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 ACPD12X40B FAQ
It is a double-rod, double-acting cylinder, so output 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 peak is 8.6 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
Only with the optional -S magnet code, which enables CMSE or DMSE reed and solid-state switches; this version (no S) carries no magnet, so no switch can be mounted. The ACPD family is discontinued - the current direct is the ACED12X40 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before ordering the swap.
