About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-100S
The ACEJ80X250-100S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 250 mm stroke down by up to 100 mm on site, giving a usable range of 150-250 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not reach. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots.

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 ACEJ80X250-100S Is Used
Gantry clamp on a machining line
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting the clamp sit inside a tight CNC fixture guard with LB foot mounting.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-100S the Right Cylinder?
Size up or down by force: a 63 mm bore pushes 1558.6 N at 0.5 MPa, while a 100 mm bore reaches 3927.0 N - pick the 80 mm when your clamp or press force sits between those bands. Remember the stop screw only shortens the extend stroke; it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange and LB foot mountings 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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-100S FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 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 250 mm extend stroke by up to 100 mm, so the working range is 150-250 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 1/8" port depends on the 80 mm bore.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome-plated 20 mm rod, and a fixed TPU bumper at both ends that decelerates the piston at stroke ends. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots; FA flange and LB foot mountings bolt straight to the ISO 21287 face.
