This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X250S, 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 ACP100X250S
The AirTAC ACP Compact Cylinder ACP100X250S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 250mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X250S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X250S
Double acting compact cylinder with a 100 mm bore and 250 mm stroke, the ACP100X250S pushes with 3927 N and pulls with 3681.6 N at 0.5 MPa, rising to 5497.8 N at 0.7 MPa. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, gantries and fixtures where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome 25 mm rod, and fixed TPU bumpers pad both ends of travel.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Note that the ACP family is discontinued: the current-production direct is the ACE100X250, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X250S (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 ACE100X250S 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 ACP100X250S Is Used
Pneumatic press station
A 100 mm bore delivering 3927 N at 0.5 MPa suits a bench-top forming or staking press on aluminium brackets, with the 250 mm stroke reaching deep into a die set.
Clamping a welding fixture
The short body fits inside the frame of a robotic welding jig, clamping steel tube assemblies with CMSE switches confirming full clamp on each cycle.
Replacing the Airtac ACP Compact Cylinder ACP100X250S with the ACE100X250S
At this bore size the step either side is significant: a 80 mm bore gives 2513.3 N push at 0.5 MPa, while stepping up is not possible within the family since 100 mm is the largest bore, so if 3927 N is marginal at your working pressure, verify the 0.7 MPa figure of 5497.8 N or parallel two cylinders. The 250 mm stroke sits inside the 300 mm maximum standard stroke for bore 100, so it is a catalogue item. Remember that a plain cylinder of this type drifts when air is lost - for a held load add a rod lock or pilot check valve. Order the ACE100X250 as the current replacement and check the ISO 21287 mounting footprint against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE100X250S
- ✓ 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 ACP100X250S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa push is 5497.8 N and pull 5154.2 N. Theoretical maximum is 800.9 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, and the 1/4" port matches the 100 mm bore.
The ACP100X250S is out of production; the current direct is the ACE100X250, 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. This unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted directly for end-of-stroke detection.
