This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X90S, 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 ACP100X90S
The AirTAC ACP Compact Cylinder ACP100X90S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 90mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X90S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X90S
A double acting DIN-standard compact cylinder, the ACP100X90S pairs a 100 mm bore with a 90 mm stroke and a 25 mm hard-chrome S45C rod on a hard-anodized aluminium body. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa those rise to 5497.8 N and 5154.2 N, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped on for end-of-stroke sensing. Air supply is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), and rod speed spans 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this bore size fits deep into presses, clamping fixtures and gantry frames where a full-length body cannot. Note the fixed TPU bumpers only soften end-of-travel - they never hold a load if air is lost, so add a rod lock or pilot check valve for held positions. This model is discontinued; the current-production direct is ACE100X90, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X90S (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 ACE100X90S 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 ACP100X90S Is Used
Baling and compacting stations
With 3927 N of push at 0.5 MPa, the 100 mm bore consolidates scrap, cardboard or textile bales in recycling lines where the 90 mm stroke sets the platen travel.
Heavy jig clamping on machining centres
The short body slots into CNC fixtures and clamping bridges too tight for a full-length profile cylinder, delivering about 240 kg of practical holding force at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP100X90S with the ACE100X90S
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa. If your load needs under 2513 N, the 80 mm bore saves space; if you need beyond 3927 N at 0.5 MPa, step up to a larger bore or run higher pressure. The 90 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so no made-to-order stroke is needed. Female M16x1.5 rod thread and 1/4" PT ports are standard here; FA/FB flange, LB foot, CA/CB clevis, CR, SDB and FTC mounts bolt to the same face. Because the piston drifts when air is removed, pair it with a rod lock for suspended loads. Order ACE100X90 as the current replacement and verify ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE100X90S
- ✓ 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 ACP100X90S 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 at 1.0 MPa is 800.9 kgf. In practice budget about 2356 N (around 240 kg equivalent) for real work at 0.5 MPa.
The hard-anodized aluminium body is a short ISO 21287-class design that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot, CA/CB clevis, CR, SDB and FTC options. The S code means the optional -S magnet is fitted, so CMSE or DMSE switches can be mounted for position feedback. The ACP100X90S is discontinued; ACE100X90 is the current direct successor - confirm ISO 21287 mounting dimensions before converting.
