About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-40B
The ACEJ100X80-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: a 100 mm bore driving an 80 mm stroke that an external stop screw trims by up to 40 mm, giving a usable range of 40-80 mm. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N, rising to 5497.8 N on push at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. The hard-anodized aluminium body with an S45C hard-chrome-plated 20 mm rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 100 mm bore slides into press fixtures and clamping gantries where a full-length cylinder will not fit. FA flange and LB foot mounts bolt straight to the ISO 21287 face, and the male rod thread (B code) suits external rod hardware.

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 ACEJ100X80-40B Is Used
Welding gantry clamp
Mounted by FA flange inside a spot-welding gantry, the short ISO 21287 body fits where an ISO 15552 profile cylinder is too long, clamping steel brackets at up to 30-500 mm/s cycle speeds.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-40B the Right Cylinder?
The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads. If position feedback matters, order the -S variant so CMSE / DMSE switches can ride the body; this model has no magnet fitted. Choose FA flange or LB foot mounting and PT ports to match the fixture.
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 ACEJ100X80-40B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N, and the theoretical maximum is 800.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 80 mm extend stroke on site, so the usable range is 40-80 mm. It cannot lengthen the stroke past 80 mm, and the stop is an end stop only, not a load-holding brake. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome-plated 20 mm rod, threaded aluminium covers, and a fixed TPU bumper at both ends that decelerates the piston at stroke ends. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. This model has no magnet, so no sensor can be mounted; order the -S code to enable CMSE / DMSE switches. Rod end is male thread (B code), ports are 1/8" PT, and FA flange or LB foot mounting bolts to the standard ISO 21287 face.
