About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-10
The ACEJ80X125-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 125 mm stroke by up to 10 mm on site, giving a usable range of 115-125 mm without changing the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical maximum of 512.6 kgf at 1.0 MPa. In practice, plan on roughly 1508 N (about 153 kg) of real work at 0.5 MPa so the actuator keeps margin for friction and pressure dips.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters on wide gantries and heavy press fixtures where every millimetre of envelope counts. A hard-anodized aluminium body runs on an S45C hard-chrome plated 20 mm rod, and fixed TPU bumpers at both ends absorb end-of-stroke shock. Air supply is 0.15-1.0 MPa (22-145 psi) with speed from 30-500 mm/s; the rod end is female M12x1.75 and the ports are 1/8" PT.

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 ACEJ80X125-10 Is Used
Press and stamping ejectors
The short compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it ejects formed sheet-metal parts from under low press beds where a full-length body will not fit.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-10 the Right Cylinder?
The 10 mm adjuster is a mechanical end stop for the extend stroke only: it shortens travel, it does not lengthen it, and on air loss the piston still drifts, so add a separate valve or lock if the load must stay put. FA flange or LB foot mounting bolts to the standard ISO 21287 face; if you need position feedback, order the -S variant so CMSE / DMSE switches can be fitted, because this non-S model carries no magnet.
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 ACEJ80X125-10 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 125 mm extend stroke by up to 10 mm, so the usable range is 115-125 mm. It is a mechanical end stop only, not a mid-stroke lock, and the piston still drifts if air is lost.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome plated 20 mm rod, female M12x1.75 rod thread and 1/8" PT ports, running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with fixed TPU bumpers at both ends. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. This model has no magnet; order the -S code to enable CMSE / DMSE reed or solid-state switches.
