This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X25SB, 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 ACP12X25SB
The AirTAC ACP Compact Cylinder ACP12X25SB 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 ACE12X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X25SB
The ACP12X25SB is a double acting DIN-standard compact cylinder with a 12 mm bore and 25 mm stroke, delivering 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa). The hard-anodized aluminium body with an S45C hard-chrome rod carries a fixed TPU bumper at both ends, and the male rod thread (B code) suits knuckle and tooling attachments. Note that this model is discontinued; the current-production replacement is the ACE12X25.
Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures, small pick stations and guarded cells. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X25SB (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 ACE12X25SB 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 ACP12X25SB Is Used
Presence check on small electronics trays
The fitted -S magnet drives a CMSE switch to confirm the 25 mm probe stroke when verifying that SMD components sit correctly in the tray pocket.
Light snap-fit press in a watch assembly cell
About 33.9 N of usable push at 0.5 MPa seats battery covers and snap clips without damaging the housing, and the male rod thread takes a small pressure foot.
Replacing the Airtac ACP Compact Cylinder ACP12X25SB with the ACE12X25SB
At 56.5 N push at 0.5 MPa this 12 mm bore covers light clamping and small-part ejection; step up to the 16 mm bore (100.5 N push at 0.5 MPa) for roughly double the force, or drop to a spring unit only if the job is single-stroke. The 25 mm stroke sits well inside the 50 mm maximum standard stroke for this bore, so it is a stock-length build. Remember a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mountings plus the fitted -S magnet for CMSE/DMSE switches let you match existing fixtures. Since ACP is discontinued, order the ACE12X25 and confirm the ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACE12X25SB
- ✓ 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 ACP12X25SB FAQ
At 0.5 MPa the 12 mm bore 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 ACP family is discontinued, so the current direct is the ACE12X25 - same bore, stroke and force class - but confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.
It is a short-body compact cylinder whose mounting length is about 50% less than an ISO 15552 profile cylinder, with a hard-anodized aluminium body, an S45C hard-chrome 6 mm rod, an M5x0.8 port and a fixed TPU bumper at each end. This SB version carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for position feedback.
