About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X225-20
A double acting ISO 21287 compact cylinder, the ACEJ80X225-20 pairs an 80 mm bore with a 225 mm stroke that an external stop screw trims on site by up to 20 mm, giving a usable extend range of 205-225 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it covers 30-500 mm/s between fixed TPU bumpers at both ends.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 225 mm stroke fits deep clamping stations and press fixtures where a full-length profile body would not. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a female M12x1.75 thread, and 1/8" PT ports feed both sides. FA flange and LB foot mounts bolt to the standard face; order the optional -S code if you later need CMSE / DMSE switch sensing - this unit ships without a magnet.

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 ACEJ80X225-20 Is Used
Pallet gate actuator on packaging lines
A 225 mm stroke swings or lifts pallet diverters in tight gantries, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X225-20 the Right Cylinder?
The 225 mm stroke sits inside the 300 mm max standard stroke for this bore, so no made-to-order build is needed. Remember the stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve for suspended loads. Match FA flange or LB foot mounting to your fixture, and add -S to the order code if position sensing via CMSE / DMSE switches is 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 ACEJ80X225-20 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, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 225 mm extend stroke by up to 20 mm, so the working range is 205-225 mm. It cannot lengthen the stroke past the ordered 225 mm, and the stop is an end stop only - it does not hold a load if air is lost.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome-plated 20 mm rod with female M12x1.75 thread, 1/8" PT ports, and fixed TPU bumpers at both ends that decelerate end-of-stroke travel. FA flange and LB foot mounts bolt to the standard face. Position sensing needs the optional -S magnet ordered with the cylinder; without -S there is no magnet and no CMSE / DMSE switch can be read.
