This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X50SB, 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 ACPD12X50SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X50SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X50SB
This is a double acting compact cylinder with a rod leaving both covers, so the 12 mm bore delivers the same 42.4 N at 0.5 MPa (59.4 N at 0.7 MPa) on every stroke because both sides work on the rod-side area. The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag while the front rod does the work. This S-coded unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke detection. Note that the ACPD family is discontinued; the current-production successor is the ACED12X50.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim jigs and tight guarding. A fixed TPU bumper sits at each end, the hard-anodized aluminium body pairs with an S45C hard-chrome rod, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X50SB (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 ACPD12X50SB Is Used
Presence check on small parts
The rear rod carries a flag past a CMSE switch while the front rod pushes a 2 kg PCB tray into a test nest, with equal 42.4 N force both ways.
Light clamping in slim fixtures
The short body fits inside narrow jig walls where a full-length cylinder will not, holding small brackets with about 25 N of usable force at 0.5 MPa.
Symmetric push-pull transfer
A through-rod on a micro-assembly station pushes a cap on one stroke and ejects it on the return, both directions delivering the same 59.4 N at 0.7 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X50SB with the ACED12X50SB
For a 12 mm bore the 42.4 N at 0.5 MPa is equal in both directions, so size the job on the rod-side figure and step up to the 16 mm bore (75.4 N at 0.5 MPa) if you need more. The 50 mm stroke is the maximum standard stroke for this bore, so no made-to-order length is involved. The male rod thread (B code) and PT ports are set by the code; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Since the ACPD is discontinued, order the ACED12X50 and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED12X50SB
- ✓ 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 ACPD12X50SB FAQ
Because a rod exits both covers, output is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa on the rod-side area, with a maximum of 8.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the bore 12 port is M5x0.8. Remember it drifts if air is lost - use a rod lock or pilot check where a load must be held.
No - the ACPD is discontinued. The current-production direct is the ACED12X50 (swap the P for an E), which matches the same 12 mm bore, 50 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, and keep the -S magnet code if you rely on CMSE or DMSE switches.
