Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10B
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 35mm 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 ACEJ12X35-10B
Its stop screw trims the extend stroke on site anywhere in the ordered 10 mm window, so the same cylinder covers a 25-35 mm working range without re-ordering. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and tight fixture pockets.
The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a male thread (the B code), and a fixed TPU bumper at each end absorbs end-of-stroke shock. Note this model has no magnet; order the -S code if CMSE / DMSE switch sensing is needed later.

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 ACEJ12X35-10B Is Used
Lab dispensing head lift
Raises and lowers a small dispensing nozzle in a benchtop filling rig; the about 3 kg vertical lift capacity with margin covers light tooling plates.
Clamp adjustment on jigs
Acts as a fine-travel clamp or stopper on assembly jigs, where the 10 mm adjustment window lets technicians dial the exact contact point without shimming.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10B the Right Cylinder?
The 35 mm stroke sits well inside the 50 mm maximum standard stroke for bore 12, so no made-to-order stroke is involved. The male rod thread (B) suits tooling that screws directly onto the rod; FA flange and LB foot mounts bolt to the ISO 21287 face. The adjuster is a mechanical end stop for the extend stroke only - it does not hold a load if air is lost. Add the -S option if you want position feedback via CMSE / DMSE switches.
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 ACEJ12X35-10B FAQ
It is double acting with a 12 mm bore, 35 mm stroke adjustable down to 25 mm via the stop screw, M5x0.8 ports, 6 mm male-thread rod, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and slim gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock. Sensing is not included on this model: the magnet is the optional -S code, and only with -S can CMSE / DMSE switches be mounted in the body slots.
