Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X225-50
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X225-50 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 225mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X225-50
A double acting ISO 21287 compact cylinder, the ACEJ80X225-50 pairs an 80 mm bore with a 225 mm stroke that an external stop screw can trim by up to 50 mm on site, giving a usable extend range of 175-225 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 80 mm bore slides into presses and gantries where a full-length cylinder will not fit. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.

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 ACEJ80X225-50 Is Used
Machine tool fixture clamping
FA flange or LB foot mounting bolts to standard ISO 21287 fixtures, and the adjustable extend stroke lets a machinist trim the clamp point on a 225 mm stroke without swapping cylinders.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X225-50 the Right Cylinder?
If the stroke must be set precisely per fixture, order the exact -NN window you need - this model carries a 50 mm window on a 225 mm stroke. The stop screw is a mechanical end stop only: on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. FA flange and LB foot mountings plus I/Y rod knuckles fit the standard face, and if you need position sensing, order the -S variant so CMSE / DMSE switches can be used - this code has no magnet fitted.
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 ACEJ80X225-50 FAQ
This 80 mm bore model pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, and 3518.6 N / 3298.7 N at 0.7 MPa, with a theoretical maximum of 512.6 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke: the -50 stop screw trims the 225 mm stroke by up to 50 mm (usable range 175-225 mm). Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, port 1/8" PT, female rod thread M12x1.75, and a fixed TPU bumper at both ends.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and tight machine frames. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the standard face. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this model (no S code) has no magnet, so no switch can be mounted on it.
