This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X25, 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 ACP12X25
The AirTAC ACP Compact Cylinder ACP12X25 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 ACE12X25 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X25
A double acting compact cylinder in the DIN-standard ACP series, the ACP12X25 pairs a 12 mm bore with a 25 mm stroke and delivers 56.5 N of push force and 42.4 N of pull at 0.5 MPa (rising to 79.2 N at 0.7 MPa). Its hard-anodized aluminium body and S45C hard-chrome rod keep the short ISO 21287-class body rigid, and the fixed TPU bumper at each end simply decelerates the piston - it never holds a load when air is lost.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this bore 12 unit slips into slim fixtures, small pick-and-place heads and tight instrument enclosures. At 0.5 MPa plan for roughly 34 N (about 3 kg) of usable vertical work rather than the full 56.5 N rating, which matches small covers, caps and lightweight parts. Note this model is discontinued: the current-production direct is ACE12X25, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X25 (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 ACE12X25 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 ACP12X25 Is Used
Small-part ejection on rotary tables
The 56.5 N push at 0.5 MPa is enough to nudge finished caps or bushings off a machining rotary table, and the short body fits beside the fixture without overhang.
Lab sample press
A 25 mm stroke and about 3 kg of practical vertical force suit gentle pressing of microscope slides, sensor lids or test-tube caps in compact benchtop equipment.
Presence check in electronics assembly
With the optional -S magnet and a CMSE switch, the cylinder confirms connector seating on PCB fixtures where a full-length body would never fit.
Replacing the Airtac ACP Compact Cylinder ACP12X25 with the ACE12X25
For light clamping or part-present duty at 25 mm stroke, bore 12 with its 56.5 N push at 0.5 MPa is the right class; step up to bore 16 (100.5 N) if the load grows, or down to nothing smaller since 12 mm is the smallest ACP bore. The 25 mm stroke sits well inside the 50 mm maximum standard stroke for this bore. This unit has the female M3x0.5 rod thread and PT ports; add the optional -S code if you later need CMSE / DMSE switch sensing, and order ACE12X25 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE12X25
- ✓ 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 ACP12X25 FAQ
At 0.5 MPa the bore 12 piston pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The model is discontinued, and the current-production direct is ACE12X25 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options on the same face. Position sensing requires the optional -S magnet code at order time; without it no magnet is fitted, so CMSE or DMSE switches cannot be mounted later.
