Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 10mm 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 ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10
The ACEJ12X10-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: a 12 mm bore, a 10 mm stroke and a 6 mm hard-chrome S45C rod. The external stop screw trims the extend stroke anywhere inside the ordered 10 mm window, giving a usable 0-10 mm range without changing hardware.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and micro-assembly heads. In practice, plan for roughly 34 N of real work at 0.5 MPa (about 60% of the rated push), which is around 3 kg held vertically with margin. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and fixed TPU bumpers absorb end-of-stroke energy. This code has no magnet; order the optional -S version if you need CMSE / DMSE switch sensing.

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 ACEJ12X10-10 Is Used
Micro-assembly part seating
A 0-10 mm adjustable press seats small connectors or pins in electronics fixtures where every millimetre of envelope counts.
Gate and escape detection
With the optional -S magnet, CMSE or DMSE switches confirm extend and retract on sorting gates and reject chutes.
Light hold-down clamps
About 34 N of usable force at 0.5 MPa clamps thin sheet or PCBs during a drilling or marking cycle.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10 the Right Cylinder?
Ports are M5x0.8 and the rod end is female M3x0.5; FA flange or LB foot mounting bolts to the standard ISO 21287 face. Remember the stop screw sets the end position only - it is not a mid-stroke lock, so the rod can drift if air is lost.
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 ACEJ12X10-10 FAQ
It is double acting with a 10 mm adjustable extend window (0-10 mm usable), M5x08 ports, a female M3x0.5 rod thread, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and a max standard stroke of 50 mm for this bore.
The ISO 21287 short body cuts mounting length by about 50% versus an ISO 15552 profile cylinder, with a hard-anodized aluminium body and fixed TPU bumpers at both ends. Sensing is not included on this code: the magnet is the optional -S order code, which then allows CMSE / DMSE reed or solid-state switches. FA flange and LB foot mounts bolt straight on.
