About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X90-40B
The ACEJ80X90-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 90 mm stroke by up to 40 mm on site, giving a usable range of 50-90 mm. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N. In practice, plan on roughly 1508 N of real work at 0.5 MPa, which is about 60% of the rated push.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 80 mm bore fits presses, gantries and guarding where a full-length body cannot. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the male (B) rod thread bolts straight into standard tooling.

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 ACEJ80X90-40B Is Used
Pallet gate actuation
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting an 80 mm bore swing heavy pallet-line gates inside tight guarding.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X90-40B the Right Cylinder?
The -40 window only shortens the extend stroke within 50-90 mm and acts as a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Order the -S code if you need the optional magnet for CMSE / DMSE switches; this model has no magnet. FA flange, LB foot and I/Y rod knuckles mount on the ISO 21287 face; PT ports as ordered.
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 ACEJ80X90-40B 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. The theoretical maximum at 1.0 MPa is 512.6 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), and speed runs 30-500 mm/s on air filtered to 40 um.
The -40 code is a 40 mm window: an external stop screw shortens the 90 mm extend stroke anywhere down to 50 mm, and fixed TPU bumpers absorb end-of-stroke energy at both ends. The stop is a mechanical end stop only, never a load-holding brake. FA flange, LB foot and I/Y knuckles fit the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; this unit ships without a magnet. For outline dimensions, confirm from datasheet.
