About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-100B
The ACEJ80X250-100B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 250 mm stroke by up to 100 mm on site, giving a usable range of 150-250 mm without changing hardware. At 0.5 MPa the 80 mm bore delivers 2513.3 N on the push stroke and 2356.2 N on the pull stroke, rising to 3518.6 N at 0.7 MPa - enough for heavy clamping, pressing and lifting duties in a short body. The rod end carries a male thread (the B code), and the air port is 1/8".
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into deep presses and guarded gantries where a full-length body will not reach. A fixed TPU bumper at each end absorbs end-of-stroke impact.

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 ACEJ80X250-100B Is Used
Automotive panel press fixture
A guarded weld-cell press that seats door panels: the short ISO 21287 body fits inside the guard envelope, and the male rod thread (B code) takes a Y knuckle for the swinging press head.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-100B the Right Cylinder?
Size this 80 mm bore when your load needs more than a 50 mm bore can give - that size pushes only 981.7 N at 0.5 MPa versus 2513.3 N here - and step to 100 mm (3927.0 N) only if 80 mm falls short. Note that the stop screw sets the extend stroke mechanically; it is not a mid-stroke lock, so the piston still drifts if air is lost. Mounting bolts straight to the ISO 21287 face: FA flange or LB foot brackets plus I/Y rod knuckles. If you need position feedback, order the -S variant so CMSE / DMSE switches can ride the body - this model 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 ACEJ80X250-100B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N, and the theoretical maximum is 512.6 kgf at 1.0 MPa. The -100 code is a 100 mm adjustment window: a stop screw on the cylinder shortens the 250 mm extend stroke by up to 100 mm, so the working range is 150-250 mm. It shortens the stroke only - it never extends past 250 mm, and it is a mechanical end stop, not a load-holding brake.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, an S45C hard-chrome rod and fixed TPU bumpers at both ends. Mounts include FA flange, LB foot and I/Y rod knuckles. Position sensing requires the optional -S magnet code - this model has no magnet, so CMSE / DMSE switches cannot be fitted unless you order the -S variant. Operating spec: 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, air filtered to 40 um.
