About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-30S
A double acting ISO 21287 compact cylinder, the ACEJ80X75-30S pairs an 80 mm bore with a 75 mm stroke and a 30 mm adjustment window. An external stop screw trims the extend stroke on site anywhere from 45 mm to the full 75 mm, so one cylinder serves several jig depths. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on extend at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into press frames and gantries where a full-length body will not fit.
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 air filtered to 40 um. Because the -S magnet is fitted on this model, CMSE or DMSE reed and solid-state switches can be clamped anywhere along the body for end-of-stroke signals. Fixed TPU bumpers at both ends absorb end-of-stroke energy.

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 ACEJ80X75-30S Is Used
Clamping fixtures on CNC machining lines
The 45-75 mm adjustable extend window lets one cylinder serve fixtures of slightly different part heights, while 2513.3 N at 0.5 MPa holds steel workpieces firmly during milling.
Short-stroke press and stake stations
With 3518.6 N available at 0.7 MPa, the 80 mm bore handles light staking and marking jobs, and the compact body fits inside press heads too shallow for a full-length profile cylinder.
Heavy gate and diverter positioning
Pull force of 2356.2 N retracts loaded conveyor gates reliably, and the fitted -S magnet with CMSE switches confirms gate position back to the PLC at each cycle.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-30S the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost and a separate holding method is needed for suspended loads. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position. Operating range is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.
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 ACEJ80X75-30S FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 75 mm extend stroke by up to 30 mm, giving a usable range of 45-75 mm. It shortens the stroke only and acts as an end stop, not a mid-stroke lock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and gantries. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted along the body slots. FA flange and LB foot mounts bolt straight to the standard face, fixed TPU bumpers absorb end-of-stroke energy, and the 20 mm rod ends in a female M12x1.75 thread with 1/8" PT ports.
