About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X30-10
The ACEJ20X30-10 is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 30 mm stroke that an external stop screw trims on site. The -10 code sets a 10 mm adjustment window, so the extend stroke can be shortened anywhere in a 20-30 mm range without changing the cylinder. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N on the extend stroke at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes it easy to fit into slim fixtures, guarding and small automation frames. A practical sizing rule: treat roughly 0.6 of the push force as usable, so plan for about 94 N of real work, equivalent to lifting about 8 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a hard-chromed S45C rod, fixed TPU bumpers absorb end-of-stroke shock at both ends, and the rod ends in a female M6x1.0 thread with a 1/8" air port.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 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 ACEJ20X30-10 Is Used
Small jig clamping
The 157.1 N push at 0.5 MPa clamps brackets or PCB fixtures on assembly benches, and the 20-30 mm adjustable range lets one cylinder serve several jig depths.
Micro part ejection
A short 20-30 mm eject stroke pushes machined pins or molded caps off small dies, where the compact body fits inside the die shoe with room to spare.
Light part lift-off
Lifts about 8 kg vertically with a 2:1 margin, enough to raise small chutes or light trays at a packaging station within the 30-500 mm/s speed range.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X30-10 the Right Cylinder?
At this force class, compare both directions of travel: the 20 mm bore gives 157.1 N push but only 117.8 N pull at 0.5 MPa, so a retract-heavy job may need the next size up, a 25 mm bore with 245.4 N push and 206.2 N pull. If 157.1 N is generous for the load, the 16 mm bore (100.5 N push) saves more space. The stop screw is a mechanical end stop only - it shortens the extend stroke within the 10 mm window but does not lock or hold a load if air is lost. Mounting: FA flange or LB foot bolt to the ISO 21287 face, and the optional -S magnet code enables CMSE / DMSE switches; without -S no magnet is fitted.
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 ACEJ20X30-10 FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N, and the theoretical maximum is 32 kgf at 1.0 MPa. It is double acting, 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 10 mm stroke adjustment window (20-30 mm usable) and a female M6x1.0 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it suits tight gantries and slim fixtures. A fixed TPU bumper at each end absorbs end-of-stroke shock. Sensing requires the optional -S magnet code, which allows CMSE / DMSE switches to ride the body slots; this model without -S carries no magnet. FA flange and LB foot mountings bolt straight on.
