About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-30
A double acting AirTAC compact cylinder built to ISO 21287, the ACEJ80X300-30 pairs an 80 mm bore with a 300 mm stroke that an external stop screw trims on site by up to 30 mm, giving a usable extend range of 270-300 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body carries an S45C hard-chrome plated rod, and a fixed TPU bumper sits at both ends.
The short ISO 21287 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 body will not reach. Speed runs 30-500 mm/s across a 0.15-1.0 MPa (22-145 psi) supply, and the FA flange or LB foot mounts bolt straight to the ISO 21287 face. No magnet is fitted; order the optional -S code if CMSE / DMSE switch sensing is needed.

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 ACEJ80X300-30 Is Used
Pallet gate actuator
Swinging or lifting a heavy pallet gate on a packaging line needs about 1500 N of usable force; the compact body fits inside the guard frame where a longer cylinder cannot.
Fixture clamp on a machining centre
Clamping a cast housing in a 4th-axis fixture: the stop screw sets the exact clamp height within 270-300 mm, and the LB foot bolts the body flat under the fixture plate.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-30 the Right Cylinder?
Choose the 80 when the 63 falls short but the 100 would oversize the envelope. The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so on air loss the piston still drifts; add a separate valve or lock for holding. FA flange and LB foot mount directly, and the female M12x1.75 rod thread accepts standard rod knuckles. Remember the -S code if you want switch positions.
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 ACEJ80X300-30 FAQ
The -30 code is a 30 mm adjustment window: an external stop screw shortens the 300 mm extend stroke on site, so the usable range is 270-300 mm. It cannot lengthen the stroke past 300 mm, and the stop is 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, S45C hard-chrome rod, 1/8" ports and a fixed TPU bumper at each end. Sensing is not included: this version has no magnet, so order the optional -S code to enable CMSE / DMSE switches. Mounting is FA flange or LB foot on the standard ISO 21287 face.
