About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10B
The ACEJ12X10-10B is a double acting compact cylinder built to ISO 21287, with a 12 mm bore and a 10 mm stroke that an external stop screw trims on site within the ordered 10 mm window, giving a usable extend range of 0-10 mm. 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 11.5 kgf at 1.0 MPa. The hard-anodized aluminium body and hard-chrome-plated S45C rod keep the short frame light yet durable, and fixed TPU bumpers absorb end-of-stroke shock at both ends.
In practice, plan on roughly 34 N of real work at 0.5 MPa (about 0.6 of the push rating), which is enough to lift about 2.9 kg vertically with a 2:1 margin. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight pick-and-place heads and small fixtures. The rod end is male thread (B code) and the port is M5x0.8. Note that no magnet is fitted unless you order the optional -S code, which enables CMSE / DMSE switch sensing.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10B Is Used
Micro part ejection
Ejects small machined pins or molded inserts from a fixture with about 34 N of usable force at 0.5 MPa, trimmed to the exact eject distance via the 10 mm window.
Compact gating on test rigs
Blocks or releases small parts on an automated test bench where the short ISO 21287 body fits inside the guard; add the -S magnet for CMSE / DMSE end-position feedback.
Small clamp actuation
Clamps lightweight PCB or connector housings in an assembly jig, lifting about 2.9 kg vertically with a 2:1 margin, with the male rod thread taking an I or Y knuckle.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10B the Right Cylinder?
At this bore size the 12 mm unit delivers 56.5 N push at 0.5 MPa. If your load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa); if less force and a smaller envelope work, there is no smaller ACEJ bore, so confirm the 12 mm fits. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve if the load must stay put. Mount with FA flange or LB foot, and order the -S variant if CMSE / DMSE position sensing is needed.
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 ACEJ12X10-10B FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 10 mm extend stroke on site, so the usable range is 0-10 mm. It cannot lengthen the stroke past the ordered 10 mm, and the stop is an end stop only - it does not hold a load on air loss. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Position sensing is possible only when you order the optional -S magnet code, which allows CMSE / DMSE switches; this model (no S code) has no magnet, so no switch can be mounted. Mounting options include FA flange and LB foot, and the male rod thread accepts I or Y knuckles.
