Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-30
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-30 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 120mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-30
The ACEJ80X120-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 120 mm stroke by up to 30 mm on site, giving a usable range of 90-120 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and gantries. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with a 20 mm hard-chrome S45C rod stands up to continuous production duty.

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 ACEJ80X120-30 Is Used
Heavy fixture clamping
Clamps large weldments or castings on a machining line, where the 90-120 mm adjustable window lets one cylinder serve several fixture heights.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-30 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 will drift if air is lost. Order FA flange or LB foot mounting to bolt straight onto the ISO 21287 face, and add the optional -S magnet code if you later need CMSE or DMSE switches; this model has no magnet fitted.
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 ACEJ80X120-30 FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push rises to 3518.6 N and pull to 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 1/8" port and an M12x1.75 female rod thread on the 20 mm rod.
An external stop screw on the extend side shortens the 120 mm stroke by up to 30 mm, so the effective range is 90-120 mm; it is a mechanical end stop, not a load-holding brake, so the rod still drifts on air loss. Fixed TPU bumpers absorb end-of-stroke energy at both ends. FA flange and LB foot mountings bolt to the ISO 21287 face. This version has no magnet, so no CMSE or DMSE switch can be read - order the optional -S magnet code if position sensing is needed.
