This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X400SB, 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 ACP100X400SB
The AirTAC ACP Compact Cylinder ACP100X400SB is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 400mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X400SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X400SB
The ACP100X400SB is a double acting compact cylinder built to the DIN-standard short-body format: a hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome 25 mm rod and a fixed TPU bumper at each end. Its 100 mm bore delivers 3927 N push and 3681.6 N pull at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters on long-stroke gantries and press fixtures where every millimetre of envelope counts. The 400 mm stroke exceeds the 300 mm standard maximum for this bore, so it is a made-to-order build. Because the S code is in the model, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. Note this model is discontinued: the current-production replacement is the ACE100X400, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X400SB (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 ACE100X400SB 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 ACP100X400SB Is Used
Heavy stamping die transfer
The 3927 N push at 0.5 MPa slides 200 kg dies between press stations, and the 400 mm made-to-order stroke covers the full shuttle length inside a tight frame.
Pallet gate actuation on packaging lines
A 1/4" port keeps flow high for 30-500 mm/s gate cycling, while the fitted -S magnet feeds CMSE switches that confirm gate open and closed to the PLC.
Replacing the Airtac ACP Compact Cylinder ACP100X400SB with the ACE100X400SB
At 0.5 MPa this bore pushes 3927 N, so size the task to about 2356 N of usable force for a comfortable margin; if the job needs under 2182 N at 0.7 MPa, a 63 mm bore (1558.6 N push at 0.5 MPa) is the smaller step, while nothing in the range is larger than 100 mm. Remember a plain ACP does not hold load when air is lost - add a rod lock or pilot check valve for held positions. The B code gives a male M16x1.5 rod thread and the 1/4" PT ports suit higher flow on this large bore. This model is discontinued; order the ACE100X400 as the direct successor and verify the ISO 21287 mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACE100X400SB
- ✓ 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 ACP100X400SB 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. The standard stroke limit for a 100 mm bore is 300 mm, so the 400 mm stroke here is a non-standard, made-to-order build - confirm lead time when ordering.
No - the ACP family is discontinued. The current direct is the ACE100X400, same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping since the ACP was DIN-standard. This S-coded unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be fitted for end-of-stroke detection.
