This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X175S, 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 ACP12X175S
The AirTAC ACP Compact Cylinder ACP12X175S is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X175S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X175S
The ACP12X175S is a double acting DIN-standard compact cylinder with a 12 mm bore and a 175 mm stroke, driving a 6 mm rod through a female M3x0.5 thread. 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 175 mm stroke is longer than the 50 mm standard maximum for this bore, so it is a made-to-order build. 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.
The hard-anodized aluminium body with threaded aluminium covers and an S45C hard-chrome rod keeps the short ISO 21287-class body roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, which is why it suits narrow gantries and guarded stations. A fixed TPU bumper at each end decelerates the piston; it never locks or holds a load, so use a rod lock or pilot check valve if the position must survive a loss of air. This model is discontinued; the current-production direct is ACE12X175, and you should confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X175S (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 ACE12X175S 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 ACP12X175S Is Used
Pick-and-place position feedback
With the -S magnet fitted, CMSE or DMSE switches confirm extension of the 6 mm rod in compact pick-and-place heads handling parts up to about 3 kg vertical equivalent at 0.5 MPa.
Small-parts ejection in assembly stations
The 56.5 N push at 0.5 MPa (79.2 N at 0.7 MPa) ejects clips, pins or stamped micro-parts from a nest, with the long 175 mm stroke reaching deep into tight tooling.
Lab and test-rig actuation
The short body and M5x0.8 ports suit benchtop test fixtures needing about 34 N of practical working force, running 30-500 mm/s on air filtered to 40 um.
Replacing the Airtac ACP Compact Cylinder ACP12X175S with the ACE12X175S
Size both ways before committing: a 16 mm bore gives 100.5 N push at 0.5 MPa if 56.5 N feels marginal, while staying at 12 mm keeps the envelope smallest. Remember the piston drifts when air is removed, so add a rod lock or pilot check valve for held loads. The 175 mm stroke is non-standard for this bore and built to order. If you need CMSE or DMSE switch feedback, this S-coded model already carries the optional -S magnet. For new projects, order the ACE12X175 instead and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE12X175S
- ✓ 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 ACP12X175S FAQ
It is a double acting 12 mm bore compact cylinder with a 175 mm made-to-order stroke. At 0.5 MPa: 56.5 N push and 42.4 N pull. At 0.7 MPa: 79.2 N push and 59.4 N pull. Theoretical maximum is 11.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, port M5x0.8, female rod thread M3x0.5, fixed TPU bumpers both ends.
No. The ACP family is discontinued. The current-production direct is ACE12X175, which matches the same bore, stroke and force class in the ISO 21287 short-body format. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The -S magnet on this unit carries over as an option on the ACE for CMSE / DMSE switches.
