Airtac ACED Double-acting Compact Cylinder ACED12X20S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED12X20S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø12mm bore and 20mm 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 ACED12X20S
A double acting compact cylinder built to ISO 21287, the ACED12X20S has a 6 mm piston rod leaving BOTH covers, so its 42.4 N output at 0.5 MPa is identical on every stroke - both directions work on the rod-side area. This 12 mm bore unit carries the optional -S magnet from the factory, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slot for end-of-stroke sensing straight away.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and miniature fixtures. A fixed TPU bumper at each end absorbs the piston's arrival, and the through-rod resists rotation while the rear rod can carry a sensor flag. For sizing: 42.4 N at 0.5 MPa means about 25 N of practical working force, and the rod lifts roughly 2 kg vertically with a 2:1 margin. Running range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

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 ACED12X20S Is Used
Micro part ejection
The 42.4 N twin-side thrust nudges small stamped or moulded parts off a nest on a rotary indexing table, with the rear rod driving a cam or flag.
Sensed presence check
With the -S magnet fitted, CMSE or DMSE switches confirm the 20 mm probe stroke on an electronics assembly line without external limit switches.
Symmetric slide drive
Equal force both directions makes the through-rod ideal for a small reciprocating shuttle that must push and pull a lightweight tray with identical force.
Is the Airtac ACED Double-acting Compact Cylinder ACED12X20S the Right Cylinder?
At 42.4 N per side, this bore 12 unit suits light clamping and small-part transfer; step up to ACED16 (75.4 N at 0.5 MPa) if the load creeps, or drop to nothing smaller - 12 mm is the smallest bore in the ACED range. Stroke 20 mm sits well inside the 50 mm standard limit for this bore. The female M3x0.5 rod thread takes standard knuckles, and the -S magnet is already fitted for CMSE / DMSE switches. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put.
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 ACED12X20S FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area, so output is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a peak of 8.6 kgf at 1.0 MPa. Never size this cylinder on a larger single-rod pull figure; there is no larger annulus side.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. The M5x0.8 ports, female M3x0.5 rod thread and FA/FB flange or LB foot brackets bolt to the standard ISO 21287 face. This -S version carries the optional magnet, so CMSE / DMSE switches mount in the body slot; a fixed TPU bumper handles end-of-stroke deceleration at 30-500 mm/s.
