About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-75S
The ACEJ80X75-75S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke anywhere in the 0-75 mm window, so one unit covers several fixture positions. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa - enough to clamp heavy weldments or index large pallets. The 80 mm bore carries a 20 mm hard-chrome-plated S45C rod and breathes through 1/8" ports.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a press jig or gantry leaves little depth. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots.

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 ACEJ80X75-75S Is Used
Machine-tool part ejector
Pushes machined housings off a fixture in a CNC cell; the short ISO 21287 body slots into the tight space behind the fixture where a full-length profile cylinder will not.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-75S the Right Cylinder?
Size against neighbours: the 63 mm bore pushes 1558.6 N at 0.5 MPa, while the 100 mm bore reaches 3927.0 N - if your load sits near 2500 N with shock or friction, step up rather than running the 80 mm at its limit. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke confirmation.
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 ACEJ80X75-75S FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; 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. The -75 code is a 75 mm adjustment window: an external stop screw shortens the extend stroke by up to 75 mm, giving a usable range of 0-75 mm. 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.
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 and fixed TPU bumpers at both ends that absorb end-of-stroke energy. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for end-position sensing. FA flange and LB foot mountings bolt straight to the ISO 21287 face.
