This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X40B, 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 ACP100X40B
The AirTAC ACP Compact Cylinder ACP100X40B is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 40mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X40B
A double acting compact cylinder in the DIN-standard ACP series, the ACP100X40B drives a 25 mm hard-chrome S45C rod from a 100 mm bore over a 40 mm stroke. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N, rising to 5497.8 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body keeps the mounting length roughly half that of an ISO 15552 profile cylinder, so this force class fits into presses, clamping fixtures and gantry frames where a full-length body simply will not go. Running range is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s and a fixed TPU bumper at each end.
For real-world sizing, treat about 2350 N (roughly 240 kg of thrust) as the usable working force at 0.5 MPa instead of the full 3927 N rating. This model is discontinued: the current-production direct is the ACE100X40 (ISO 21287, same bore, stroke and force class), so confirm the ISO 21287 mounting dimensions before swapping. Note the B code gives a male rod thread and the port is 1/4" PT.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X40B (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 ACE100X40B 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 ACP100X40B Is Used
Heavy die clamping on stamping presses
The 3927 N push at 0.5 MPa clamps sheet-metal stamping dies in 40 mm of travel, and the short body slots into press bolster space a full-length cylinder cannot occupy.
Injection mold ejector assist
The 3681.6 N pull stroke strips parts from injection molds, with the male rod thread (B code) taking a knuckle for direct ejector-plate linkage.
Replacing the Airtac ACP Compact Cylinder ACP100X40B with the ACE100X40B
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa versus 2513.3 N for the 80 mm bore, so step down to 80 if you need under 2500 N and this size if your die or fixture needs more. If 40 mm of travel is short for the job, bore 100 accepts standard strokes up to 300 mm. Remember that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. The B code specifies a male rod thread for I/Y knuckles; FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face. Position sensing needs the optional -S magnet code with CMSE / DMSE switches. Order the ACE100X40 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE100X40B
- ✓ 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 ACP100X40B 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 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. It is double acting - air extends and retracts the rod.
Order the ACE100X40, the ISO 21287 successor made by swapping the P for an E. It matches the same 100 mm bore, 40 mm stroke and force class with a short body and compatible mounting family (FA/FB flange, LB foot, CA/CB clevis). Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before the swap. Also note the port is 1/4" and the optional -S magnet code is required for CMSE / DMSE switches.
