Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10B
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10B 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 ACEJ12X30-10B
The ACEJ12X30-10B is a double acting compact cylinder built to ISO 21287, with a 12 mm bore and a 30 mm stroke that an external stop screw trims by up to 10 mm on site, giving a usable extend range of 20-30 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The male rod thread (B code) on the 6 mm rod bolts straight into small tooling plates.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarded cells where a full-length body will not fit. A practical sizing rule: keep real work to about 34 N (roughly 3.4 kg force), which means it lifts about 2.8 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, and the magnet is the optional -S code - this unit has none, so CMSE or DMSE switches cannot be fitted unless you order -S.

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 ACEJ12X30-10B Is Used
Micro part ejection
Knocks small pressed or moulded parts off a nest on an assembly bench, where the 20-30 mm trimmed stroke clears the part without over-travel.
Compact test stations
Applies light contact force to small PCBs or sensors in a go/no-go gauge; at 0.5 MPa the push stays gentle enough for delicate work.
Small lid press-down
Seats caps or covers on vials and connectors in packaging cells, lifting about 2.8 kg vertically with margin on light lids.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10B the Right Cylinder?
If your load needs more than about 34 N of usable force at 0.5 MPa, step up to the 16 mm bore (100.5 N push) or the 20 mm bore (157.1 N push); for lighter pick-and-place under 50 N, this 12 mm bore keeps cost and space down. Remember 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 and I/Y rod knuckles fit the ISO 21287 face; order the -S variant if you need position sensing.
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 ACEJ12X30-10B FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window: a stop screw on the front shortens the 30 mm extend stroke to any setting between 20 and 30 mm. It is an end stop only - on air loss the piston drifts, so it does not hold a load. Speed range is 30-500 mm/s and operating pressure is 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 fixed TPU bumper at each end and an M5x0.8 air port. Mounts include FA flange, LB foot and I/Y rod knuckles on the standard face. Position sensing needs the optional -S magnet code - this model (no S) has no magnet, so CMSE or DMSE switches cannot be detected until you order the -S variant.
