About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10
The ACEJ12X35-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A stop screw on the body trims the 35 mm stroke by up to 10 mm on site, giving a usable range of 25-35 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures, small guarding and bench-top tooling. A hard-anodized aluminium body runs on an S45C hard-chrome plated rod, with a fixed TPU bumper at each end to absorb end-of-stroke impact. Air ports are M5x0.8 and the rod end carries a female M3x0.5 thread. Speed range is 30-500 mm/s over 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 ACEJ12X35-10 Is Used
Reject gate on a lab conveyor
Short 25-35 mm strokes and a body about 50% shorter than an ISO 15552 profile cylinder fit the tight space under a narrow inspection conveyor to push off failed parts.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10 the Right Cylinder?
Remember the stop screw is a mechanical end stop only - on air loss the piston drifts, so it is not a load-holding lock. Mount with FA flange or LB foot brackets, and if you need position sensing, order the -S variant so CMSE / DMSE switches can be fitted; this model has no magnet.
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 ACEJ12X35-10 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The extend stroke is adjustable from 25 to 35 mm via the external stop screw (10 mm window). Operating pressure 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, fluid air filtered to 40 um. Port is M5x0.8, rod thread female M3x0.5.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end absorbs end-of-stroke impact. FA flange and LB foot brackets bolt to the standard face. Position sensing requires the optional -S magnet with CMSE / DMSE switches - this model, ordered without the S code, carries no magnet, so no sensor can be mounted on it.
