Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X100-10S
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X100-10S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø20mm bore and 100mm stroke, 1/8" 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 ACEJ20X100-10S
A double acting compact actuator built to ISO 21287, the ACEJ20X100-10S pairs a 20 mm bore with a 100 mm stroke and an external stop screw that trims the extend stroke by up to 10 mm on site, giving a usable 90-100 mm range. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, enough for light clamping and part-presenting duty. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight fixtures and guarding where a full-length body will not fit.
In practice, plan on roughly 94 N of usable push at 0.5 MPa, which lifts about 9 kg vertically - halve that to about 4 kg if you want a 2:1 margin on a real part weight. The hard-anodized aluminium body carries a 10 mm S45C hard-chrome rod with a female M6x1.0 thread, and the -S code on this model means the magnet is fitted, so CMSE / DMSE switches can be mounted anywhere along the body slots. A fixed TPU bumper at each end absorbs end-of-stroke energy, and speed spans 30-500 mm/s.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ20X100-10S Is Used
Small fixture clamping
The 157.1 N push at 0.5 MPa seats light workpieces in drill or assembly jigs, and the 10 mm window lets you dial the clamp point between 90 and 100 mm without shimming.
Gated part-present stations
With the -S magnet fitted, CMSE or DMSE switches confirm extend and retract positions on a pick-and-place gate, all inside a body about 50% shorter than an ISO 15552 profile cylinder.
Light vertical eject in packaging
Pushing about 9 kg equivalent vertically at 0.5 MPa, the 20 mm bore kicks small cartons or trays off a conveyor lane at up to 500 mm/s.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X100-10S the Right Cylinder?
Size both ways before you commit: the 16 mm bore gives 100.5 N push at 0.5 MPa if your load is lighter, while the 25 mm bore reaches 245.4 N if you need more headroom. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve if the load must stay put. This model ships with the -S magnet fitted and a female M6x1.0 rod thread; FA flange and LB foot mounts bolt straight to the ISO 21287 face, and PT ports are standard.
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 ACEJ20X100-10S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum is 32 kgf at 1.0 MPa. The bore is 20 mm with a 100 mm stroke adjustable down to 90 mm via the stop screw, ports are 1/8", the rod is 10 mm with a female M6x1.0 thread, operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and speed runs 30-500 mm/s.
An external stop screw shortens the extend stroke by up to 10 mm within the ordered -10 window, so the rod stops anywhere from 90 to 100 mm; it is a mechanical end stop, not a mid-stroke lock. The -S code on this unit means the magnet is fitted, so CMSE / DMSE reed or solid-state switches mount in the body slots. The fixed TPU bumpers at both ends absorb end-of-stroke energy, and FA flange or LB foot mounts attach to the standard ISO 21287 face.
