This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X25SFB, 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 ACP12X25SFB
The AirTAC ACP Compact Cylinder ACP12X25SFB 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 ACE12X25SFB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X25SFB
The ACP12X25SFB is a double acting DIN-standard compact cylinder with a 12 mm bore and 25 mm stroke, delivering 56.5 N of push and 42.4 N of pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa). Its hard-anodized aluminium body with an S45C hard-chrome rod runs at 30-500 mm/s on air filtered to 40 um, across 0.15-1.0 MPa (22-145 psi) and -20 to +70 C. The -S code on this unit means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
Because the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, it slots into slim fixtures, small pick stations and instrument panels where a full-length body simply will not fit. Fixed TPU bumpers decelerate the piston at both ends but never hold a load - if the rod must stay put when air is lost, add a rod lock or pilot check valve. 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 ACE12X25SFB (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 ACE12X25SFB 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 ACP12X25SFB Is Used
Lab sample ejector
Ejects microplate or vial samples from a nest in diagnostic equipment; 56.5 N push at 0.5 MPa is ample for light plastic parts, and the fitted magnet signals home position via a CMSE switch.
Small-part push-off in assembly heads
Pushes finished bushings or pins off an arbor on a rotary indexing table; the 25 mm stroke clears the part in a compact envelope where a full-length body would not fit.
Presence-check probe in test rigs
Advances a go/no-go feeler against a machined housing; with the -S magnet fitted, a DMSE switch confirms the probe reached the part before the test cycle starts.
Replacing the Airtac ACP Compact Cylinder ACP12X25SFB with the ACE12X25SFB
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa suits light clamping, sensing probes and small part ejection. If your load needs more, step up to the 16 mm bore for 100.5 N push at 0.5 MPa; if 56.5 N is generous, there is no smaller bore below 12 mm in this family. The FB flange ordered with this unit bolts the cylinder face-on to a plate; CA/CB clevis and LB foot options cover other fixings. This model carries the optional -S magnet, so position feedback with CMSE / DMSE switches is available out of the box. Since ACP is discontinued, order ACE12X25 as the current equivalent and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE12X25SFB
- ✓ 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 ACP12X25SFB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The cylinder is double acting, runs 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, and uses an M5x0.8 port.
Order ACE12X25, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 25 mm stroke and force class in a matching short body. The FB flange, CA/CB clevis and LB foot mountings carry over, and the -S magnet option with CMSE / DMSE switches is still available. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your drawing before committing the swap.
