This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X175B, 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 ACP12X175B
The AirTAC ACP Compact Cylinder ACP12X175B 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 ACE12X175B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X175B
The ACP12X175B is a double acting DIN-standard compact cylinder with a 12 mm bore and a made-to-order 175 mm stroke, well beyond the 50 mm standard limit for this bore. 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 B code gives a male rod thread on the 6 mm rod, and the port is M5x0.8.
Its hard-anodized aluminium body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding. This model is discontinued: the current-production direct is the ISO 21287 ACE12X175, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X175B (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 ACE12X175B 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 ACP12X175B Is Used
Lab sample ejector
Ejects sample trays or slides from a compact analytical station, where the 56.5 N push at 0.5 MPa is ample and the long 175 mm reach clears a shallow enclosure.
Small-part ejection on assembly benches
Pushes finished micro-components off a nest into a chute; the male rod thread (B code) accepts a custom ejector tip directly.
Light gate actuation
Swings or trips a small mechanism in a test rig; note the 175 mm stroke is made to order, and without the -S magnet no CMSE/DMSE switch can report position.
Replacing the Airtac ACP Compact Cylinder ACP12X175B with the ACE12X175B
At 12 mm bore you are at the bottom of the range: 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 56.5 N is generous for the job, there is no smaller ACP bore. The 175 mm stroke is non-standard for this bore (standard tops out at 50 mm), so it is made to order. The B code selects a male rod thread; omit it for a female thread. No magnet is fitted, so position switches cannot be used - order the -S version if you need CMSE or DMSE sensors. Order the ACE12X175 instead, the current ISO 21287 replacement.
Replacement checklist
- ✓ Current-production ACE → ACE12X175B
- ✓ 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 ACP12X175B FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting with a 12 mm bore, 175 mm made-to-order 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.
Yes, but it is a non-standard, made-to-order stroke, so lead time differs from stock models. The ACP family itself is discontinued; the current-production replacement is the ISO 21287 ACE12X175, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
