About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-20
The ACEJ80X75-20 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 20 mm on site, giving a usable 55-75 mm range without changing the cylinder. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa - enough muscle for heavy clamping and press-fit work in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the FA flange or LB foot mounts bolt straight to the ISO 21287 face. This code has no magnet - order the optional -S version if you need CMSE / DMSE switch sensing.

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 ACEJ80X75-20 Is Used
Heavy jig clamping on machining lines
Clamps cast-iron pump or gearbox castings against fixtures; the short ISO 21287 body fits inside machine guards where a full-length profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-20 the Right Cylinder?
The -20 window suits fixtures where the final position is tuned after installation - remember the stop screw only shortens the extend stroke and does not hold a load if air is lost. Specify FA flange or LB foot to match your fixture, PT ports as standard, and add the -S code if position feedback 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 ACEJ80X75-20 FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push reaches 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 20 mm rod, 1/8" PT port and female M12x1.75 rod thread.
The -20 code means an external stop screw shortens the 75 mm extend stroke by up to 20 mm, so the working range is 55-75 mm; it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts on air loss. The fixed TPU bumpers at both ends absorb end-of-stroke energy. This version has no magnet, so no switch can be read - order the optional -S magnet code to enable CMSE / DMSE reed or solid-state switches. FA flange and LB foot mountings bolt to the ISO 21287 face.
