About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-30
A double acting ISO 21287 compact cylinder, the ACEJ80X45-30 pairs an 80 mm bore with a 45 mm stroke that an external stop screw trims by up to 30 mm, giving a usable extend range of 15-45 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 ceiling 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 heavy presses and gantries where a full-length body will not fit.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the optional -S magnet code enables CMSE / DMSE switch sensing; without -S no magnet is fitted.

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 ACEJ80X45-30 Is Used
Pallet gate actuation
Swings heavy guard gates on packaging lines; the short ISO 21287 body needs about half the mounting length of an ISO 15552 profile cylinder behind tight machine frames.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-30 the Right Cylinder?
Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mount on the ISO 21287 face with FA flange or LB foot hardware, add I or Y rod knuckles as needed, and order the -S code if CMSE / DMSE switches are planned.
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 ACEJ80X45-30 FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push is 3518.6 N and pull 3298.7 N; theoretical maximum is 512.6 kgf at 1.0 MPa. It is double acting with a 45 mm stroke adjustable down to 15 mm via the 30 mm stop-screw window, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), -20 to +70 C, 30-500 mm/s, 1/8" PT ports, M12x1.75 female rod thread, max standard stroke 300 mm for this bore.
The hard-anodized aluminium body with threaded aluminium covers saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper absorbs end-of-stroke energy at both ends - it never locks or holds a load. FA flange, LB foot and I/Y knuckles bolt to the ISO 21287 face. Position sensing needs the optional -S magnet code, which allows CMSE / DMSE switches; without -S there is no magnet in the piston.
