This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X15SB, 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 ACP12X15SB
The AirTAC ACP Compact Cylinder ACP12X15SB is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X15SB
The ACP12X15SB is a double acting DIN-standard compact cylinder with a 12 mm bore and 15 mm stroke, built around a hard-anodized aluminium body and an S45C hard-chrome piston rod. 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 maximum 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 slim fixtures where a full-length body simply will not fit.
The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body for end-of-stroke sensing. The B code gives a male rod thread on the 6 mm rod, and the port is M5x0.8. A fixed TPU bumper at each end decelerates the piston, and speed runs 30-500 mm/s. Note this model is discontinued: the current-production replacement is the ACE12X15, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X15SB (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 ACE12X15SB 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 ACP12X15SB Is Used
Micro part ejection from jigs
The 56.5 N push at 0.5 MPa is enough to nudge small plastic clips or stamped pins off a locating jig, and the 15 mm stroke keeps the tooling block shallow.
Position-confirmed gating on test rigs
With the -S magnet fitted, a CMSE or DMSE switch confirms the rod is fully home before an electronic test sequence starts on a bench-top fixture.
Sample press in lab automation
A 15 mm stroke at up to 79.2 N (0.7 MPa) seats vial caps or presses microscope slides into holders inside compact analyser housings.
Replacing the Airtac ACP Compact Cylinder ACP12X15SB with the ACE12X15SB
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa. If your load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N); if you need less travel force, this is the floor. The 15 mm stroke sits well inside the 50 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order length. The male rod thread (B code) suits I/Y rod knuckles, and the -S magnet fitted here works with CMSE / DMSE switches. Remember that a plain cylinder of this type drifts when air is lost - for a held load add a rod lock or pilot check valve. Order the ACE12X15 as the current direct replacement and verify the ISO 21287 mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACE12X15SB
- ✓ 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 ACP12X15SB 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; theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting with a 12 mm bore, 15 mm stroke, 6 mm male-thread rod, M5x0.8 port, operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s and fixed TPU bumpers at both ends.
Order the ACE12X15, the ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class and drops into the same short-body envelope, but because the ACP was DIN-standard you should confirm the ISO 21287 mounting dimensions and port positions against your fixture before committing.
