Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10SB
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10SB is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 10mm 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 ACEJ12X10-10SB
A double acting micro cylinder with an adjustable extend stroke, the ACEJ12X10-10SB pairs a 12 mm bore with a 10 mm stroke that a stop screw trims anywhere in the 0-10 mm range. 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 ceiling 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 pick-and-place heads and micro fixtures.
For sizing, treat roughly 34 N (about 0.6 of the push force) as the practical working effort at 0.5 MPa; vertically that corresponds to lifting about 2.9 kg with a 2:1 margin. The S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slot for end-of-stroke signalling. The B code gives a male M3x0.5 rod thread, and a fixed TPU bumper at each end absorbs end-of-stroke shock.

Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10SB Is Used
Micro part ejection
Ejects small plastic or metal parts from an injection or stamping die with a short 0-10 mm adjustable push of 56.5 N at 0.5 MPa.
Sensor-checked sorting
With the fitted magnet, CMSE or DMSE switches confirm the trimmed stroke position on a small-parts sorting station.
Lab sample indexing
Indexes vials or slides in compact laboratory automation where the short ISO 21287 body fits inside tight instrument frames.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X10-10SB the Right Cylinder?
At this bore size the realistic choice is down or up: the ACEJ12X10-10SB sits above nothing in the range, while a bore 16 unit raises push force to 100.5 N at 0.5 MPa if 56.5 N feels marginal. Keep in mind the stop screw only shortens the extend stroke and does not lock position - on air loss the piston drifts, so add a separate clamp if holding is needed. Male rod thread (B) suits clevis-style tooling; FA flange or LB foot mounts bolt to the ISO 21287 face.
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 ACEJ12X10-10SB 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 the theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting with a 10 mm stroke adjustable over a 10 mm window, runs on air filtered to 40 um at 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, with a 6 mm rod, male M3x0.5 thread and M5x0.8 ports.
An external stop screw shortens the 10 mm extend stroke anywhere within the ordered 10 mm window, so usable travel is 0-10 mm; it is a mechanical end stop, not a mid-stroke lock. The S code means the magnet is fitted on this unit, so CMSE or DMSE switches can be mounted in the body slot. The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, and FA flange or LB foot brackets bolt straight on.
