About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-30
A double acting ISO 21287 compact cylinder, the ACEJ80X40-30 pairs an 80 mm bore with a 40 mm stroke and a 30 mm adjustable window: an external stop screw trims the extend stroke on site anywhere from 10 to 40 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length cylinder simply will not fit.
The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a female M12x1.75 thread, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a load-holding brake. FA flanges, LB feet and I/Y rod knuckles 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 ACEJ80X40-30 Is Used
Machine stopper gate
On a conveyor line, the adjustable 10-40 mm extend stroke actuates a pop-up stopper or reject gate, tuned on site without changing hardware.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-30 the Right Cylinder?
If your fixture needs position feedback, order the -S variant to enable CMSE / DMSE switches; this non-S model has no magnet and accepts no sensors. The 30 mm window means the machine can be tuned down to a 10 mm extend stroke without re-plumbing. Ports are 1/8" PT on both ends, and the max standard stroke for this bore is 300 mm if a longer variant is ever needed.
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 ACEJ80X40-30 FAQ
The -30 code is a 30 mm adjustment window: an external stop screw shortens the 40 mm extend stroke down to 10 mm, so the usable range is 10-40 mm. It runs double acting on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Sensors are possible only on the -S variant, which carries the optional magnet for CMSE / DMSE switches - this model has none. FA flange, LB foot, FTC brackets and I/Y rod knuckles mount directly; the rod end is female M12x1.75 with 1/8" PT ports.
