About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10S
The ACEJ12X35-10S is a double acting ISO 21287 compact cylinder with a 12 mm bore and a 35 mm stroke that can be trimmed on site. An external stop screw shortens the extend stroke by up to 10 mm, giving a usable range of 25-35 mm without changing the cylinder. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa.
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 guarding where a full-length body cannot. The hard-anodized aluminium barrel carries an S45C hard-chrome rod with an M3x0.5 female thread, and fixed TPU bumpers absorb end-of-stroke shock at both ends. Because the -S magnet is fitted, CMSE / DMSE switches can be clipped onto the body for end-of-travel 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 ACEJ12X35-10S Is Used
Small-part ejection from jigs
A 34 N working push at 0.5 MPa is enough to kick machined pins or bushings out of a drilling jig, and the 25-35 mm trimmed stroke lets the operator set the exact ejection distance.
Position-verified test stations
With the -S magnet fitted, CMSE or DMSE switches confirm the rod has reached the trimmed end position on a compact electronics test fixture, all inside a body about 50% shorter than an ISO 15552 profile cylinder.
Light clamping of small housings
Holding a sensor housing or connector block during a screwdriving step needs only a few tens of newtons; the M5x0.8 ports and FA flange make plumbing and mounting quick on tight automation plates.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-10S the Right Cylinder?
Match the 25-35 mm trimmed range to your fixture before ordering, and remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange and LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts 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 ACEJ12X35-10S FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The extend stroke is adjustable from 25-35 mm via the stop screw, speed range is 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and the port is M5x0.8 with an M3x0.5 female rod thread.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome rod, threaded aluminium covers and fixed TPU bumpers at both ends to soften end-of-stroke impact. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for end-of-travel detection.
