This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X20B, 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 ACPD12X20B
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X20B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X20B
Double acting with a rod leaving both covers, the ACPD12X20B is a DIN-standard compact cylinder for tight spaces: 12 mm bore, 20 mm stroke, 6 mm rod and an M5x0.8 port. Because both strokes work on the rod-side area, output is 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa in either direction - there is no push/pull difference to design around. The male rod thread (B code) bolts straight to tooling, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body will not fit. Note this model is discontinued: the current-production direct is ACED12X20 (swap the P for an E), so confirm ISO 21287 mounting dimensions before swapping. Speed range is 30-500 mm/s with fixed TPU bumpers at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X20B (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 ACPD12X20B Is Used
Micro-part ejection
The 42.4 N per-side thrust at 0.5 MPa pushes small machined or moulded parts off a nest, and the 20 mm stroke keeps the station footprint minimal.
Flag-driven position sensing
The rear rod can mount a flag so a CMSE or DMSE switch (with the -S magnet option) confirms end-of-stroke on an assembly-line checking station.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X20B with the ACED12X20B
At 42.4 N per side at 0.5 MPa, the 12 mm bore suits light clamping and small-part transfer; step up to the 16 mm bore (75.4 N) for a little more grip or down to a direct-acting mini actuator below 40 N. The through-rod gives a symmetric mount and rear-rod sensing, and the male thread (B) suits knuckle or fixture studs. If you need position feedback, order the -S variant, which carries the optional magnet for CMSE / DMSE switches - this non-S code has no magnet at all. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. For new designs, specify ACED12X20 instead.
Replacement checklist
- ✓ Current-production ACE → ACED12X20B
- ✓ 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 ACPD12X20B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, with a maximum of about 8.6 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. A fixed TPU bumper sits at each end.
Order ACED12X20, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 20 mm stroke and force class in a matching short body. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions and the FA/FB flange or LB foot interfaces before swapping. If you also need switch feedback, check the -S magnet option on the replacement.
