About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30S
The ACEJ12X30-30S is a double acting ISO 21287 compact cylinder with a 12 mm bore and a 30 mm stroke that an external stop screw trims anywhere in a 30 mm window, so one unit covers 0-30 mm of extend travel. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N and 59.4 N at 0.7 MPa. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into slim fixtures, pick stations and instrument panels where a full-length body simply will not fit.
The hard-anodized aluminium body carries a 6 mm S45C hard-chrome rod with a female M3x0.5 thread, and this -S version carries the optional magnet so CMSE / DMSE switches can report end positions. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

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 |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30S Is Used
Semiconductor test fixture
In a wafer inspection jig the 0-30 mm adjustable window lets technicians set exact probe travel, while the fitted magnet feeds DMSE switch signals to the controller.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30S the Right Cylinder?
Keep the 30 mm window only if you truly need to dial the stroke down to near zero; a fixed-stroke ACE12X30 is simpler otherwise. Remember the stop screw is a mechanical end stop, not a mid-stroke lock - on air loss the rod still drifts. FA flange or LB foot brackets and I/Y rod knuckles bolt to the ISO 21287 face, and PT ports take M5x0.8 fittings.
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 ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), operates from -20 to +70 C at 30-500 mm/s, and the -30 code gives a 30 mm adjustment window on the 30 mm stroke via an external stop screw.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and tight jigs. Fixed TPU bumpers absorb end-of-stroke energy at both ends. This model already carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots; FA flange, LB foot and I/Y knuckle hardware attach to the standard ISO 21287 face.
