Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30 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 ACEJ12X30-30
A double acting compact actuator built to ISO 21287, the ACEJ12X30-30 pairs a 12 mm bore with a 30 mm stroke that an external stop screw trims anywhere in the 0-30 mm range. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N / 59.4 N at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures, small guards and bench-top tooling where a full-length body simply will not fit.
In practice, plan on roughly 34 N of usable push at 0.5 MPa (about 60% of the rating), which corresponds to lifting around 3 kg vertically with a 2:1 margin - enough for light caps, small levers or sensor-actuated slides. The hard-anodized aluminium body carries a hard-chromed S45C rod, a fixed TPU bumper at each end absorbs end-of-stroke shock, and the rod ends in a female M3x0.5 thread. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

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 ACEJ12X30-30 Is Used
Micro ejection on SMT fixtures
The 0-30 mm trim lets a technician dial the exact eject travel for pushing finished PCBAs off a test nest, with 56.5 N push at 0.5 MPa ample for lightweight boards.
Lab sample clamping
Around 34 N of practical clamping force holds small vials or slide holders during dispensing, and the compact body fits inside benchtop instrument enclosures.
Small-batch carton tab folding
The stop screw sets a repeatable fold depth on cosmetic cartons, and the female M3x0.5 rod thread accepts custom folding pads.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30 the Right Cylinder?
At the 12 mm bore you get 56.5 N push at 0.5 MPa; step up to the 16 mm bore for 100.5 N or drop to the smallest class if space is even tighter. The -30 window means the 30 mm extend stroke can be shortened by up to 30 mm on site, ideal when the exact stop position is set during machine commissioning. Note the stop screw is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts. This version has no magnet; order the -S code if you later need CMSE / DMSE switch position feedback. FA flange or LB foot mounts bolt to the standard 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 ACEJ12X30-30 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 12 mm bore has an M5x0.8 port, a 6 mm rod with female M3x0.5 thread, a 30 mm stroke adjustable down to 0 mm via the stop screw, speed 30-500 mm/s, pressure 0.15-1.0 MPa (22-145 psi) and a 1.5 MPa (215 psi) proof rating.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA flange or LB foot mounting options. Position sensing is not included in this version: the -S code adds the optional magnet that enables CMSE / DMSE switches, so order ACEJ12X30-30S if feedback is required.
