This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X400S, 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 ACP100X400S
The AirTAC ACP Compact Cylinder ACP100X400S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 400mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X400S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X400S
Double acting with air powering both the extend and retract stroke, the ACP100X400S pairs a 100 mm bore with a 400 mm stroke and delivers 3927 N push and 3681.6 N pull at 0.5 MPa. At 0.7 MPa those figures rise to 5497.8 N and 5154.2 N, with a theoretical peak of 800.9 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome rod keep the short ISO 21287-class package rigid over the long stroke, and the -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the tube.
Note the 400 mm stroke is beyond the 300 mm standard limit for this bore, so it is a made-to-order build. This model is discontinued; the current direct is the ACE100X400, and you should confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X400S (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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
| Max (@1.0 MPa) | 801 kgf | |
The ACE100X400S 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 ACP100X400S Is Used
Press die clamping stack
In a stamping shop the 5497.8 N push at 0.7 MPa seats heavy die shoes or hold-down blocks, and the short body fits the tight daylight between bolster plates where a full-length cylinder cannot.
Scissor-lift gate actuator
A factory safety gate or scissor platform driven by this cylinder gets 3681.6 N of pull at 0.5 MPa on the return stroke, with the fitted -S magnet feeding CMSE or DMSE switches for open and closed confirmation.
Replacing the Airtac ACP Compact Cylinder ACP100X400S with the ACE100X400S
At this force class the 100 mm bore is already near the top of the range, so step down only for lighter work: an 80 mm bore gives 2513.3 N push at 0.5 MPa, while there is no larger standard bore above 100 mm. The 400 mm stroke exceeds the 300 mm standard maximum, so order it as a non-standard made-to-order unit. Because a plain cylinder drifts when air is lost, add a rod lock or pilot check valve if the load must stay put. The magnet is included via the -S code for CMSE / DMSE switch mounting, and the current replacement is the ACE100X400 - verify ISO 21287 mounting dimensions before converting.
Replacement checklist
- ✓ Current-production ACE → ACE100X400S
- ✓ 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 ACP100X400S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa it pushes 5497.8 N and pulls 5154.2 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The model is discontinued, and the current-production replacement is the ACE100X400 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, as the ACP followed a DIN standard.
The bore 100 standard stroke tops out at 300 mm, so 400 mm is a non-standard made-to-order build. Each end carries a fixed TPU bumper that only decelerates the piston - it is not adjustable and it never locks or brakes a load, so use a rod lock or pilot check valve where position must be held. The rod end is a female M16x1.5 thread and the air port is 1/4" PT.
