This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X325S, 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 ACP100X325S
The AirTAC ACP Compact Cylinder ACP100X325S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 325mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X325S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X325S
A double acting compact cylinder built to the DIN-standard short-body format, the ACP100X325S pairs a 100 mm bore with a 325 mm stroke and delivers 3927 N push and 3681.6 N pull at 0.5 MPa. Because the ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, this force level fits into presses, gantries and guarding where a full-length body would not. The 325 mm stroke exceeds the 300 mm standard limit for this bore, so it is a made-to-order build.
The hard-anodized aluminium body carries an S45C hard-chrome 25 mm rod with a female M16x1.5 thread, and the -S code means the optional magnet is fitted, so CMSE or DMSE switches can be mounted directly on the body for end-position sensing. Note that this model is discontinued: the current-production direct is the ACE100X325, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X325S (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 ACE100X325S 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 ACP100X325S Is Used
Baling and compacting station
The 3927 N push at 0.5 MPa suits a scrap or packaging compactor ram, and the 325 mm stroke gives the long approach a deep bin or hopper needs.
Fixture clamp on a machining centre
The short ISO 21287-class body mounts inside tight fixture plates where an ISO 15552 profile cylinder would overhang, with CMSE or DMSE switches confirming clamp state.
Replacing the Airtac ACP Compact Cylinder ACP100X325S with the ACE100X325S
Size both ways before committing: a 80 mm bore gives 2513.3 N push at 0.5 MPa, while stepping up is not possible because 100 mm is the largest bore in this family. If your load needs more than about 240 kg of usable force at 0.5 MPa, this is the right class. The 325 mm stroke is non-standard for this bore (300 mm max standard), so order it as a made-to-order item. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. A plain cylinder of this type drifts when air is lost, so add a rod lock or pilot check valve for held loads. Replacement: ACE100X325, same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACE100X325S
- ✓ 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 ACP100X325S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa push rises to 5497.8 N and pull to 5154.2 N. The theoretical maximum is 800.9 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, speed 30-500 mm/s, and the 325 mm stroke is made to order since the bore's standard limit is 300 mm.
No - the ACP family is discontinued. The current-production replacement is the ACE100X325, an ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions and port positions before swapping. The fixed TPU bumpers at both ends simply decelerate the piston at each end of travel and do not hold a load when air is lost.
