About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10SB
The ACEJ12X15-10SB is a double acting AirTAC compact cylinder built to ISO 21287, with a 12 mm bore and a 15 mm stroke that an external stop screw trims by up to 10 mm, giving a usable extend range of 5-15 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N and 59.4 N at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into small fixtures where a full-length body will not fit.
Because the bore is small, plan the work around roughly 34 N of usable push at 0.5 MPa (about 0.6 of the rated figure), which corresponds to lifting about 3 kg vertically - and about 1.5 kg if you want a 2:1 margin. The male rod thread (B code) carries an M3x0.5 external thread, the -S magnet is fitted so CMSE / DMSE switches can be mounted, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10SB Is Used
Small-part ejection from micro molds
The 56.5 N push at 0.5 MPa is enough to eject connector housings or watch components from shallow cavities, and the 5-15 mm trimmed stroke matches short part-drop travel.
Presence-check probe on electronics assembly lines
With the fitted -S magnet driving a CMSE or DMSE switch, the rod confirms a PCB or bracket is seated, retracting under air since the cylinder is double acting.
Light gate latch on a carton sealing head
About 3 kg of vertical lift equivalent at 0.5 MPa lets this 12 mm bore latch a lightweight guard gate, with the TPU bumper quieting each end of the 15 mm travel.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10SB the Right Cylinder?
At this bore size the 56.5 N push at 0.5 MPa suits light clamping, sorting and sensor push tasks rather than heavy pressing. If your load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N); if 56.5 N is generous, the same family starts at bore 12 so there is nothing smaller to drop to. The 15 mm stroke sits well inside the 50 mm maximum standard stroke for this bore, so no made-to-order stroke is needed.
The 10 mm adjustment window is a mechanical end stop for the extend stroke only - it shortens travel, it does not hold a load if air is lost. Mount with FA flange or LB foot brackets on the ISO 21287 face, and remember the -S magnet on this model is what enables CMSE / DMSE switch position feedback.
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 ACEJ12X15-10SB FAQ
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 maximum of 11.5 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 15 mm extend stroke on site to any setting between 5 and 15 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air pressure is lost.
This is an ISO 21287 compact cylinder whose short aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for end-position detection. FA flange and LB foot brackets bolt to the standard ISO 21287 face, and the B code gives a male M3x0.5 rod thread with an M5x0.8 air port.
