Airtac ACED Double-acting Compact Cylinder ACED12X20B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED12X20B 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 ACED12X20B
A double acting compact cylinder with a rod leaving both covers, the ACED12X20B pushes with identical force on every stroke because both sides work on the rod-side area: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa. The 12 mm bore takes an M5x08 port, runs on air filtered to 40 um between 0.15-1.0 MPa (22-145 psi) and moves at 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slips into slim pick-and-place heads and test fixtures. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body carries the 6 mm S45C hard-chrome rod, and the male rod thread (B code) bolts straight to your tooling. Plan on roughly 25 N of usable push at 0.5 MPa, which lifts about 2 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 (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 ACED12X20B Is Used
Micro part ejection
The symmetric 42.4 N push in both directions ejects small stamped or moulded parts from a die, with the 20 mm stroke matching shallow pockets.
Lab sample indexing
Compact enough for benchtop analyser trays, the double rod keeps the carrier square while advancing samples 20 mm at 30-500 mm/s.
Small fixture clamping
With about 25 N of practical working force at 0.5 MPa, the male-threaded rod clamps light brackets or PCBs inside tight jig frames.
Is the Airtac ACED Double-acting Compact Cylinder ACED12X20B the Right Cylinder?
For this 12 mm bore the 42.4 N at 0.5 MPa suits light clamping and small part transfer; step up to the 25 mm bore (206.2 N at 0.5 MPa) when the load grows, or drop to a shorter stroke if 20 mm is more than the travel you need. The through-rod resists rotation and lets the rear rod carry a fixture or flag. Note that with no air the piston drifts, so add a rod lock or pilot check if a load must stay put. FA/FB flange, LB foot and FTC brackets mount on the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches - this code has no magnet fitted.
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 ACED12X20B FAQ
Output is equal in both directions because a rod exits each cover and both strokes use the rod-side area: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, 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 and temperature -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and fixed TPU bumpers at both ends absorb end-of-stroke impact. Sensing needs the optional -S magnet code; this model (no S) carries no magnet, so CMSE or DMSE switches cannot be read on it. FA/FB flange, LB foot and FTC brackets bolt to the standard face.
