This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X125SB, 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 ACP12X125SB
The AirTAC ACP Compact Cylinder ACP12X125SB is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X125SB
Double acting and DIN-standard compact, the ACP12X125SB moves its 6 mm rod with air in both directions and carries a fixed TPU bumper at each end. At 0.5 MPa the 12 mm bore delivers 56.5 N push and 42.4 N pull, rising to 79.2 N and 59.4 N at 0.7 MPa. Its 125 mm stroke is longer than the 50 mm standard for this bore, so it is a made-to-order build. The hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
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 compact assemblies. Because the S code is in this model, the optional -S magnet is fitted and CMSE or DMSE switches can be read directly. Note this model is discontinued: the current direct is ACE12X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X125SB (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 ACE12X125SB 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 ACP12X125SB Is Used
PCB fixture clamping
The 56.5 N push at 0.5 MPa seats small circuit boards into a test nest, while the fitted -S magnet with a CMSE switch confirms the clamp is fully home.
Lab sample pusher
A 125 mm stroke slides sample trays between two stations on a compact benchtop analyzer, with the 42.4 N pull returning the carriage each cycle.
Small carton ejector
Mounted on an LB foot bracket, the rod nudges light cartons off a conveyor lane; the short body fits under a low guard where a full-length cylinder cannot.
Replacing the Airtac ACP Compact Cylinder ACP12X125SB with the ACE12X125SB
At 56.5 N push at 0.5 MPa this 12 mm bore suits light clamping and small part transfer; step up to the 16 mm bore (100.5 N) for more force or stay at 12 mm where space is tightest. The 125 mm stroke is non-standard for this bore (50 mm max standard), so expect a made-to-order unit. The male rod thread (B code) and PT ports are set at ordering, and the fitted -S magnet lets you add CMSE / DMSE switches for end-of-stroke sensing. A plain cylinder of this type drifts when air is lost, so add a rod lock or pilot check valve if the load must be held. This model is discontinued - order ACE12X125 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE12X125SB
- ✓ 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 ACP12X125SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push and 59.4 N pull. The theoretical maximum is 11.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed is 30-500 mm/s.
No - the ACP family is discontinued. The current-production direct is ACE12X125, which matches the same 12 mm bore, 125 mm stroke and force class. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions of the ACE before swapping. The ACE keeps the short body that saves about 50% of the length of an ISO 15552 profile cylinder, and the -S magnet option carries over for CMSE / DMSE switch mounting.
