About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X10-10S
The ACEJ20X10-10S is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 10 mm stroke that an external stop screw can trim anywhere in a 0-10 mm window on site. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, enough for light clamping and positioning in tight fixtures. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into jigs and gantries where a full-length body will not fit.
The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a female M6x1.0 thread, and fixed TPU bumpers absorb end-of-stroke shock at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots. As a rule of thumb, plan for about 94 N of real work at 0.5 MPa (roughly 60% of the push rating), which corresponds to lifting about 8 kg vertically with a 2:1 margin.

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 ACEJ20X10-10S Is Used
Small-part clamping fixture
The 157.1 N push at 0.5 MPa clamps aluminium brackets or plastic housings in a drilling jig, with the 0-10 mm adjustable window tuned to each part thickness.
Positioned eject on an assembly bench
With the -S magnet fitted, CMSE or DMSE switches confirm rod position as the short-stroke pusher kicks finished components off a nest.
Compact gate latch on a packaging line
The body is about 50% shorter than an ISO 15552 profile cylinder, so it latches guarding doors inside a machine frame where space is minimal.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X10-10S the Right Cylinder?
At 20 mm bore this sits mid-range for light work: the 16 mm bore gives 100.5 N push at 0.5 MPa if your load is smaller, while the 25 mm bore raises that to 245.4 N for heavier clamps. Both ports stay 1/8". Note that the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod can drift if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet lets you add CMSE / DMSE switches for end-of-stroke 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 ACEJ20X10-10S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The 20 mm bore runs on 0.15-1.0 MPa (22-145 psi) filtered air, proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/8" port - written correctly as 1/8" - and a 0-10 mm adjustable extend stroke.
An external stop screw shortens the 10 mm extend stroke anywhere within the ordered 10 mm window, so usable stroke runs from 0 to 10 mm; it is a mechanical end stop only and never holds a load on air loss. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots. Fixed TPU bumpers at both ends absorb end-of-stroke energy, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.
