Airtac ACED Double-acting Compact Cylinder ACED12X25SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED12X25SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø12mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACED Double-acting Compact Cylinder ACED12X25SB
A double acting compact cylinder built to ISO 21287, the ACED12X25SB pushes with a rod on BOTH covers, so the 12 mm bore delivers 42.4 N at 0.5 MPa (59.4 N at 0.7 MPa) in each direction - both strokes work on the rod-side area. The male rod thread (B code) suits inline tooling, and the through-rod resists rotation while the rear rod can carry a sensor flag. The hard-anodized aluminium body with S45C hard-chrome plated rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this bore class fits slim pick-and-place heads and micro gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock. The S in the model code means the optional magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots. For real-world sizing, plan on roughly 25 N of usable work at 0.5 MPa - about 2 kg held 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 (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 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 ACED12X25SB Is Used
Micro part ejection
Ejects finished watch or connector components from a mold nest; the 42.4 N both-ways force and 25 mm stroke clear small parts without disturbing the fixture.
Sensed slide on a compact tester
The fitted -S magnet drives CMSE or DMSE switches for end-position confirmation inside a benchtop leak or vision station where body length is critical.
Symmetric push-pull gate
The through-rod pushes a small divertor gate equally in both directions on a packaging line, with the male thread simplifying inline clevis-free linkage.
Is the Airtac ACED Double-acting Compact Cylinder ACED12X25SB the Right Cylinder?
At 42.4 N per direction, this 12 mm bore suits light clamping and small part transfer; step up to the 16 mm bore (75.4 N at 0.5 MPa) for heavier micro loads, or down to nothing smaller - this is the smallest ACED bore. The 25 mm stroke sits inside the 50 mm maximum standard stroke for bore 12, so it is a catalog item. The male rod thread (B) plus PT ports and the fitted -S magnet for CMSE / DMSE switches make it a complete sensing-ready unit; add FA flange or LB foot brackets to bolt it into standard fixtures. Note that it will not hold a load if air is lost - use a rod lock or pilot check where position must be kept.
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 ACED12X25SB FAQ
Because a rod exits both covers, output is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa per direction, with a maximum of 8.6 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, temperature -20 to +70 C, air filtered to 40 um. Port is M5x0.8 and the rod end is male thread (B code).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and jigs. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots for stroke-end detection. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA flange or LB foot brackets bolt to the standard ISO 21287 face.
