Airtac ACED Double-acting Compact Cylinder ACED25X90S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X90S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED25X90S
The ACED25X90S is a double acting compact cylinder built to ISO 21287, with a piston rod leaving BOTH covers so the 25 mm bore delivers an identical 206.2 N at 0.5 MPa in each direction - both strokes work on the rod-side area. The through-rod resists rotation and light side load, and the rear rod end doubles as a mount for a sensor flag. Its hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding.
The S code means the optional magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped on for end-of-stroke detection. A fixed TPU bumper at each end absorbs stroke-end impact, the S45C hard-chrome rod is 10 mm, and the female M6x1.0 rod thread takes standard knuckles. As a planning figure, treat roughly 123 N (about 12.6 kg) as the usable working force at 0.5 MPa, or expect it to lift about 10 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED25X90S Is Used
Fixture clamping on CNC pallets
The equal 206.2 N force in both directions lets one ACED25X90S clamp and unclamp a machined aluminium bracket with identical grip, and the 90 mm stroke clears the pallet changer in a tight envelope.
Reject pusher on a packaging line
Mounted on LB feet beside a conveyor, the through-rod keeps the pusher shoe from rotating as it kicks off-spec cartons at up to 500 mm/s, with CMSE switches confirming home and fire positions.
Sample lift in a lab autosampler
With about 10 kg of vertical lift capacity at a 2:1 margin, the double rod guides a small sample tray symmetrically, and the rear rod carries a flag past a DMSE sensor for repeat counting.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X90S the Right Cylinder?
At 206.2 N per direction the 25 mm bore sits between the 20 mm (117.8 N) and 32 mm (345.6 N) double-rod sizes; step up to 32 mm if your fixture needs more margin, or down to 20 mm for lighter pick-and-place heads. The 90 mm stroke is well inside the 150 mm standard range for this bore, so no made-to-order build is required. Choose FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles to match the ISO 21287 face, and remember the -S magnet is already on this model for CMSE / DMSE switching. If the load must stay put when air is lost, add a rod lock or pilot check - the cylinder itself will drift.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED25X90S FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area, so force is equal either way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, and the bore 25 model takes an M5x0.8 port with a female M6x1.0 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, freeing space in guarded cells and sliding gantries. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots for position feedback. A fixed TPU bumper at each end softens stroke-end impact, and FA/FB flange, LB foot or FTC brackets bolt straight to the standard face.
