About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-75B
The ACEJ80X80-75B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 80 mm stroke by up to 75 mm on site, giving a usable range of 5-80 mm without changing the cylinder. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, so it carries real clamp and press loads in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a male thread (B code), a fixed TPU bumper at each end, and the optional -S magnet enables CMSE / DMSE switches; this unit has no magnet fitted, so no sensor can be mounted as delivered.

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 ACEJ80X80-75B Is Used
Palletizing drop-down stopper
The 75 mm adjustment window lets a line engineer trim the extend stroke between 5 and 80 mm to match carton heights on a palletizer, with the TPU bumper absorbing the end-of-stroke shock at 30-500 mm/s.
Gantry clamp on a CNC fixture
The short ISO 21287 body mounts under a machine guard where an ISO 15552 profile cylinder is about twice as long; the male rod thread (B) takes a Y knuckle for clamping toggle linkages.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-75B the Right Cylinder?
Ports are 1/8" on the 63, 80 and 100 mm bores. Remember the stop screw only shortens the extend stroke within the ordered 75 mm window and is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange and LB foot mountings bolt to the ISO 21287 face, and PT ports are standard (order G for BSPP).
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 ACEJ80X80-75B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull is 3298.7 N; theoretical maximum is 512.6 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 80 mm extend stroke on site, so the usable range is 5-80 mm. It cannot lengthen the stroke past 80 mm, and the stop is an end stop only - it does not hold a load if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a 20 mm hard-chrome S45C rod with male thread, 1/8" PT ports and a fixed TPU bumper at both ends. Position sensing requires the optional -S magnet code, which allows CMSE or DMSE switches; this model (no S code) has no magnet, so no switch can be mounted. FA flange and LB foot mountings fit the standard ISO 21287 face.
