This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X25S, 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 ACP100X25S
The AirTAC ACP Compact Cylinder ACP100X25S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 25mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X25S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X25S
Double acting on both strokes, the ACP100X25S pairs a big 100 mm bore with a very short 25 mm stroke, pushing 3927 N and pulling 3681.6 N at 0.5 MPa (5497.8 N push at 0.7 MPa). The short ISO 21287-class body cuts roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into press fixtures and end-of-arm tooling where a full-length body will not reach. A fixed TPU bumper sits at each end of travel, and the optional -S magnet this model carries lets CMSE or DMSE switches report rod position.
Note this model is discontinued: the current-production direct is the ACE100X25, which keeps the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping. Running spec: 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, 30-500 mm/s, -20 to +70 C, hard-anodized aluminium body with an S45C hard-chrome rod and a female M16x1.5 rod thread.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X25S (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 ACE100X25S 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 ACP100X25S Is Used
Press-fit clamping of gearbox housings
The 3927 N push at 0.5 MPa gives a 100 mm bore enough force to seat bearings or press dowels into aluminium housings on a short-stroke assembly press, with the 25 mm stroke matching the part's insertion depth.
Weld fixture swing-and-lock slides
A compact 25 mm stroke is ideal for locking pins and locating wedges on automotive weld fixtures, where the short body fits inside the fixture frame and CMSE switches confirm pin engagement via the -S magnet.
Replacing the Airtac ACP Compact Cylinder ACP100X25S with the ACE100X25S
At 3927 N push and 3681.6 N pull at 0.5 MPa, the 100 mm bore sits at the top of the ACP range; step down to the 80 mm bore (2513.3 N push) if the load is lighter, or stay here when clamping forces approach 4 kN. The 25 mm stroke is well inside the 300 mm maximum standard stroke for this bore. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. This unit ships with the -S magnet fitted for CMSE / DMSE switches, PT ports, and FA/FB flange, LB foot or CA/CB clevis mounting. Order the ACE100X25 as the current replacement and verify ISO 21287 hole patterns first.
Replacement checklist
- ✓ Current-production ACE → ACE100X25S
- ✓ 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 ACP100X25S FAQ
At 0.5 MPa the cylinder pushes 3927 N and pulls 3681.6 N; at 0.7 MPa push rises to 5497.8 N (pull 5154.2 N), and the theoretical maximum is 800.9 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, rod thread female M16x1.5, port 1/4" PT.
Order the ACE100X25, the ISO 21287 successor made by swapping the P for an E. It matches this model's 100 mm bore, 25 mm stroke and force class, and accepts the same FA/FB flange, LB foot and CA/CB clevis hardware family. Because the ACP was built to a DIN-standard compact format, confirm the ISO 21287 mounting dimensions against your fixture before committing the swap. The -S magnet code carries over, so CMSE / DMSE switching remains available.
