About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-50
The ACEJ80X75-50 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 50 mm on site, giving a usable range of 25-75 mm without swapping the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical maximum of 512.6 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 80 mm bore fits tight presses, guards and gantries where a full-length body will not. A hard-anodized aluminium body carries a hard-chrome plated S45C rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the 1/8" PT ports feed speeds of 30-500 mm/s. The magnet is not fitted on this code; order the -S version if you later need CMSE or DMSE switch sensing.

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 ACEJ80X75-50 Is Used
Short-stroke press station
Clamping or forming aluminium brackets in a welding cell, where the 25-75 mm adjustable window lets the die position be tuned on the machine and 2513.3 N at 0.5 MPa does the work.
Gantry pick-and-place lift
Raising cast housings of about 120 kg on a robot gantry, using the compact body to fit inside the Z-axis frame where an ISO 15552 profile cylinder would be too long.
Bottle-line reject pusher
Kicking off-spec packs from a conveyor at 30-500 mm/s, with the stop screw set to a shorter extend stroke so the pusher clears the lane quickly between cartons.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-50 the Right Cylinder?
If your jig needs roughly 1500 N of usable force, this 80 mm bore already carries a healthy margin at 0.5 MPa line pressure. The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so on air loss the piston can still drift; add a separate holding valve if the load must stay put. FA flange or LB foot mounts bolt to the ISO 21287 face, and the female M12x1.75 rod thread accepts standard rod knuckles. This code has no magnet, so position sensing requires the -S variant.
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 ACEJ80X75-50 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N; the theoretical maximum is 512.6 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 75 mm extend stroke by up to 50 mm, so the working range is 25-75 mm. It shortens the stroke only and never extends it past the ordered 75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
It is an ISO 21287 compact cylinder, about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a hard-anodized aluminium body, hard-chrome plated S45C rod, and fixed TPU bumpers at both ends that absorb end-of-stroke energy. Mounts such as FA flange and LB foot bolt to the ISO 21287 face, and the female M12x1.75 rod thread takes standard rod accessories. This code has no magnet; order the optional -S version to enable CMSE or DMSE switches. Air must be filtered to 40 um, and the unit works from -20 to +70 C.
