This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X25B, 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 ACP Compact Cylinder ACP12X25B
The AirTAC ACP Compact Cylinder ACP12X25B is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X25B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X25B
The ACP12X25B is a double acting compact cylinder in the DIN-standard ACP family, with a 12 mm bore and 25 mm stroke. Air extends and retracts the 6 mm hard-chrome rod, and a fixed TPU bumper sits at each end of the hard-anodized aluminium body. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those figures rise to 79.2 N and 59.4 N, with a theoretical peak of 11.5 kgf at 1.0 MPa.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into small jigs and test fixtures where a full-length body will not fit. Note this model is discontinued: the current-production successor is ACE12X25, so confirm ISO 21287 mounting dimensions before swapping. The B code gives a male rod thread; the optional -S magnet enables CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X25B (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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACE12X25B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP12X25B Is Used
Lab sample ejector
The 56.5 N push at 0.5 MPa is enough to eject slide-mounted sample trays from a compact analytical tester, and the short body fits the tight instrument housing.
Micro-part clamping
A 25 mm stroke clamps small electronics housings in a drill jig, with the male rod thread taking an I knuckle for a swing clamp arm.
Small parts presence check
With the optional -S magnet and a CMSE switch, the cylinder signals end-of-stroke when confirming a connector is seated in an assembly nest.
Replacing the Airtac ACP Compact Cylinder ACP12X25B with the ACE12X25B
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. If your load needs more, step up to the 16 mm bore (100.5 N push) or the 20 mm bore (157.1 N). For lighter pick-and-place work under about 3 kg vertical, this size is usually enough. The 25 mm stroke is well inside the 50 mm maximum standard stroke for this bore. Choose the B code for a male rod thread, add LB foot or FA/FB flange brackets to suit the fixture, and order the -S code only if you need the magnet for CMSE / DMSE switches. Since ACP is discontinued, spec ACE12X25 as the direct replacement and verify the ISO 21287 mounting pattern.
Replacement checklist
- ✓ Current-production ACE → ACE12X25B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP12X25B FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N. At 0.7 MPa it pushes 79.2 N and pulls 59.4 N. The theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and cycles at 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA/FB, LB or CA/CB mounting options. The ACP12X25B is discontinued; the current direct is ACE12X25 - confirm the ISO 21287 mounting dimensions before ordering.
