This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X25SB, 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 ACP100X25SB
The AirTAC ACP Compact Cylinder ACP100X25SB 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 ACE100X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X25SB
A double acting compact cylinder in the 100 mm bore class, the ACP100X25SB delivers 3927 N of push force and 3681.6 N of pull force at 0.5 MPa, rising to 5497.8 N on extension at 0.7 MPa. The male rod thread (B code) and the optional -S magnet fitted to this unit let CMSE or DMSE switches report end positions directly on the machine.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class build about 50% shorter in mounting length than an ISO 15552 profile cylinder, which is why it suits tight press fixtures and gantry clamps. A fixed TPU bumper sits at both ends and simply decelerates the piston; it never holds a load, so use a rod lock or pilot check valve where position must be kept. Note that this model is discontinued: the current-production replacement is ACE100X25, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X25SB (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 ACE100X25SB 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 ACP100X25SB Is Used
Heavy press fixture clamping
The 3927 N push at 0.5 MPa clamps steel weldments in automotive fixture bases, with the short body fitting inside the fixture riser where a full-length profile cylinder cannot.
Gantry stamping and marking heads
A 25 mm stroke is ideal for stamping or dot-peen heads on gantry frames; the male rod thread takes a knuckle or tool plate directly, and CMSE switches confirm each hit via the -S magnet.
Pallet gate and stopper actuation
Conveyor gate stoppers for pallet loads need the 100 mm bore force class; the fixed TPU bumper tames end-of-travel impact at 30-500 mm/s cycling speeds.
Replacing the Airtac ACP Compact Cylinder ACP100X25SB with the ACE100X25SB
At 100 mm bore this is the largest size in the family, pushing 3927 N at 0.5 MPa where an 80 mm bore reaches 2513.3 N and there is no larger standard bore above it. If your clamp or press needs under 2500 N, step down to ACP80; if you need the full 800.9 kgf theoretical class, this is the ceiling. The 25 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order length. Because the piston drifts when air is lost, pair it with a rod lock or pilot check valve for held loads. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face, and the -S magnet on this code accepts CMSE / DMSE switches. Order ACE100X25 as the current direct and verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACE100X25SB
- ✓ 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 ACP100X25SB FAQ
Push is 3927 N and pull is 3681.6 N at 0.5 MPa; at 0.7 MPa push rises to 5497.8 N and pull to 5154.2 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is a double acting compact cylinder, 100 mm bore, 25 mm stroke, 25 mm rod, 1/4" port, male rod thread, operating on 0.15-1.0 MPa (22-145 psi) with 30-500 mm/s speed and a fixed TPU bumper at both ends.
Order ACE100X25, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The ACE family also carries the same FA/FB, LB and CA/CB mounting options, and position sensing is available with the optional -S magnet for CMSE / DMSE switches.
