This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X50B, 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 ACPD12X50B
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X50B 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 ACED12X50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X50B
A double acting compact cylinder with a rod leaving both covers, the ACPD12X50B delivers the same 42.4 N at 0.5 MPa on every stroke because both sides work on the rod-side area. The 12 mm bore and 50 mm stroke sit at the top of the bore-12 standard range, and the male rod thread (B code) bolts straight to I/Y knuckles. Its hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into slim pick-and-place heads and test fixtures.
The through-rod resists rotation and light side load and gives a symmetric mount, while fixed TPU bumpers at each end take the end-of-stroke hit. Note this model is discontinued: the current-production direct is the ACED12X50, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X50B (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 ACPD12X50B Is Used
Micro part ejection
The 42.4 N through-rod pushes small machined bushings off a CNC fixture from either side, and the 50 mm stroke clears the fixture wall in a tight envelope.
Lab slide actuation
Equal 42.4 N force in both directions moves a microscope sample stage back and forth at 30-500 mm/s, with the back rod carrying a home-position flag.
Connector press-fit
About 25 N of usable force seats ribbon-cable connectors in small electronics assemblies, with the TPU bumpers softening each end of the 50 mm travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X50B with the ACED12X50B
At 42.4 N per direction this is the smallest ACPD force class; if your load needs more, the 16 mm bore gives 75.4 N at 0.5 MPa in the same compact body style. The 50 mm stroke is the maximum standard stroke for bore 12, so no made-to-order length is needed. This unit has no magnet, so CMSE or DMSE switches cannot be used; order the -S version if position sensing matters. Since a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check for held loads. For new builds, specify the ACED12X50 instead.
Replacement checklist
- ✓ Current-production ACE → ACED12X50B
- ✓ 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 ACPD12X50B FAQ
Because a rod exits both covers, force is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, both on the rod-side area. Maximum force at 1.0 MPa is 8.6 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speed 30-500 mm/s, and the rod is 6 mm with a male thread.
The ISO 21287-class short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with M5x0.8 ports and FA/FB flange or LB foot mounting. The ACPD12X50B is discontinued; the current direct is the ACED12X50 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering.
