This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X40, 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 ACP100X40
The AirTAC ACP Compact Cylinder ACP100X40 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 ACE100X40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X40
A double acting compact cylinder with a 100 mm bore and 40 mm stroke, the ACP100X40 pushes with 3927 N and pulls with 3681.6 N at 0.5 MPa, rising to 5497.8 N at 0.7 MPa. Its hard-anodized aluminium body and S45C hard-chrome rod come in a short ISO 21287-class package that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy clamping fixtures where a full-length body will not fit. Air supply runs 0.15-1.0 MPa (22-145 psi) with rod speed from 30-500 mm/s, and a fixed TPU bumper sits at both ends.
This model is discontinued: the current-production direct is the ACE100X40, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, and note the optional -S magnet is required if you want CMSE or DMSE switches fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X40 (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 ACE100X40 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 ACP100X40 Is Used
Heavy press-fit clamping
The 3927 N push at 0.5 MPa seats bearing housings or shaft collars in automotive machining fixtures over a short 40 mm throw.
Weld fixture swing-and-clamp stations
Body-in-white jigs use the short body to clamp panel edges with about 2356 N of usable force where a longer cylinder cannot fit.
Bale or carton compression gate
Packaging lines use the 100 mm bore to hold compression plates against stacked cartons, with the 1/4" port feeding high flow at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP100X40 with the ACE100X40
At 3927 N push and 3681.6 N pull on a 40 mm stroke, this bore suits heavy short-throw clamping and pressing. If your load is lighter, the 80 mm bore delivers 2513.3 N push at 0.5 MPa; if you need more, step up is not available beyond 100 mm in this family, so consider parallel units. A plain ACP100X40 does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check valve for held loads. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. Order the ACE100X40 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE100X40
- ✓ 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 ACP100X40 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa it pushes 5497.8 N and pulls 5154.2 N. Theoretical maximum force at 1.0 MPa is 800.9 kgf. It is double acting with a 25 mm rod, M16x1.5 female rod thread, 1/4" ports and a fixed TPU bumper at each end. Operating range is 0.15-1.0 MPa (22-145 psi).
Order the ACE100X40, the current-production ISO 21287 successor: swap the P for an E and you get the same 100 mm bore, 40 mm stroke and force class in a matching short body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN standard. FA/FB flange, LB foot and CA/CB clevis options carry over, and the optional -S magnet still enables CMSE / DMSE switches.
