About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-100
A double acting ISO 21287 compact cylinder, the ACEJ80X125-100 pairs an 80 mm bore with a 125 mm stroke and a 100 mm adjustment window: an external stop screw trims the extend stroke anywhere between 25 and 125 mm on site. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome plated 20 mm rod stand up to continuous clamping and pressing duty.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy weld fixtures and press gantries where a full-length body will not reach. Fixed TPU bumpers absorb end-of-stroke shock at both ends, and the optional -S magnet enables CMSE / DMSE switch position feedback.

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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-100 Is Used
Small press and forming stations
With 3518.6 N available at 0.7 MPa, the 80 mm bore drives light staking, riveting and marking heads on assembly lines where the compact body fits inside the press frame.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-100 the Right Cylinder?
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 for suspended loads. FA flange or LB foot mounts bolt to the ISO 21287 face, and order the -S code if CMSE / DMSE switches are planned.
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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-100 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -100 code is a 100 mm adjustment window: an external stop screw shortens the 125 mm extend stroke by up to 100 mm, giving a usable range of 25-125 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/8" PT port and M12x1.75 female rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits deep inside guards and fixtures. FA flange and LB foot mounts bolt straight to the standard face, and I / Y rod knuckles are available. Position feedback requires the optional -S magnet ordered with the cylinder; without it no magnet is fitted and CMSE / DMSE switches cannot be mounted. Fixed TPU bumpers at both ends absorb end-of-stroke shock.
