About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-40B
The ACEJ100X75-40B 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 40 mm on site, giving a usable range of 35-75 mm without changing the cylinder. At 0.5 MPa the 100 mm bore pushes 3927 N and pulls 3769.9 N, rising to 5497.8 N at 0.7 MPa, with a theoretical maximum of 800.9 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into press fixtures and gantries where a full-length body will not fit. The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a male thread (the B code), a fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). No magnet is fitted on this version; order the -S code if you later need CMSE / DMSE switch position feedback.

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 (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3770 N |
| 0.7 MPa | 5278 N |
| Max (@1.0 MPa) | 769 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 ACEJ100X75-40B Is Used
Gate and fixture positioning
On steel-processing lines it indexes heavy weld gates through a 35-75 mm window, with FA flange mounting and a male rod thread tying into existing tooling.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-40B 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. FA flange or LB foot mounts bolt to the ISO 21287 face, and the male rod thread suits rod knuckles and custom tooling; add the optional -S magnet only when CMSE / DMSE sensing is actually required.
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 ACEJ100X75-40B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa those figures rise to 5497.8 N and 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 75 mm extend stroke on site to any length from 35 to 75 mm. It is a mechanical end stop only, so the piston still drifts on air loss.
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, 1/8" PT ports and a fixed TPU bumper at each end. FA flange and LB foot mounts bolt straight to the ISO 21287 face. Position sensing needs the optional -S magnet code, which enables CMSE / DMSE switches; this model without -S carries no magnet.
