This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X150B, 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 ACP12X150B
The AirTAC ACP Compact Cylinder ACP12X150B is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X150B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X150B
The ACP12X150B is a double acting compact cylinder in the DIN-standard ACP series, built with a hard-anodized aluminium body, an S45C hard-chrome rod and a fixed TPU bumper at each end. At the 12 mm bore it delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N push at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 150 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build. Note that this model is discontinued; the current-production successor is ACE12X150.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and tight machine frames. This version carries the B code for a male rod thread and a PT port thread; the optional -S magnet code is what enables CMSE / DMSE switch mounting, and this unit has no magnet fitted. Confirm ISO 21287 mounting dimensions before swapping to the ACE.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X150B (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 ACE12X150B 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 ACP12X150B Is Used
Small-part ejection from test fixtures
The 56.5 N push at 0.5 MPa is enough to tip lightweight PCBs or small housings off a test nest, and the 150 mm reach clears deep fixture pockets.
Lab sample pusher in compact analysers
A short-body cylinder fits inside benchtop instrument frames where a full-length profile cylinder cannot, moving sample trays of a few hundred grams with margin.
Light gate and flap actuation on packaging lines
Swinging small divert flaps or gating blister packs needs only a few newtons; the 2.9 kg vertical-lift equivalent covers these duties comfortably at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP12X150B with the ACE12X150B
At 12 mm bore this is the smallest force class in 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, so consider a single-acting ASP/ATP for spring-return duty - all of these are now covered by the ACE family. The 150 mm stroke is non-standard for this bore (50 mm max standard) and is made to order. This B-code version gives a male rod thread; add the -S code only if you need CMSE / DMSE position switches. Remember that a plain cylinder drifts when air is lost - use a rod lock or pilot check valve for held loads. Order ACE12X150 as the current direct after confirming ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE12X150B
- ✓ 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 ACP12X150B FAQ
Bore 12 mm, stroke 150 mm (non-standard; the bore's max standard stroke is 50 mm, so this is made to order). Push 56.5 N and pull 42.4 N at 0.5 MPa; push 79.2 N and pull 59.4 N at 0.7 MPa; theoretical maximum 11.5 kgf at 1.0 MPa. Port is M5x0.8, rod is 6 mm with a male thread (B code), speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi).
Only if the -S magnet code is ordered - the magnet is an option, not a default, and this ACP12X150B has no magnet fitted. With the -S version, AirTAC CMSE or DMSE reed and solid-state switches clamp to the body groove. Also note the model is discontinued: ACE12X150 is the current ISO 21287 replacement, so confirm its mounting dimensions before ordering.
