Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10S
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 30mm 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 ACEJ12X30-10S
The ACEJ12X30-10S is a double acting ISO 21287 compact cylinder with a 12 mm bore and a 30 mm extend stroke that an external stop screw trims by up to 10 mm, giving a usable range of 20-30 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those figures rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The magnet fitted under the -S code lets CMSE or DMSE switches report end positions without any extra bracket work.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into slim pick-and-place heads and small fixtures where a full-length body simply will not fit. In practice, plan on roughly 34 N of real work at 0.5 MPa (about 60% of the push rating), which lifts around 3 kg vertically - halve that to about 1 kg if you want a 2:1 margin on a vertical lift. The hard-anodized aluminium body carries a 6 mm S45C hard-chrome rod with a female M3x0.5 thread, and fixed TPU bumpers absorb end-of-stroke shock at both ends.

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 ACEJ12X30-10S Is Used
Micro part ejection
Ejects small machined pins or molded inserts off a fixture with 56.5 N of push at 0.5 MPa, trimmed to 20-30 mm so the ejector never over-travels.
Position-verified clamping
The fitted -S magnet drives CMSE / DMSE switches to confirm the 30 mm clamp stroke on a compact electronics assembly jig.
Lab sample indexing
Advances sample trays or vial racks in a compact analyzer head, where the short body fits about 50% closer than an ISO 15552 profile cylinder.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10S the Right Cylinder?
At this bore size the neighbours matter: a 16 mm ACEJ delivers 100.5 N push at 0.5 MPa if 56.5 N is marginal, while stepping down is not possible since 12 mm is the smallest ACEJ bore. The stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod will drift if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. Runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C.
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 ACEJ12X30-10S FAQ
At 0.5 MPa: 56.5 N push and 42.4 N pull. At 0.7 MPa: 79.2 N push and 59.4 N pull. Theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke (10 mm window, usable 20-30 mm), M5x0.8 ports, a 6 mm rod with female M3x0.5 thread, speed 30-500 mm/s, and operating pressure 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and gantries. Fixed TPU bumpers absorb end-of-stroke energy at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slot; without the -S code there is no magnet. FA flange and LB foot mounts bolt straight to the ISO 21287 face.
