About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-50
A double acting ISO 21287 compact cylinder, the ACEJ80X120-50 pairs an 80 mm bore with a 120 mm stroke and a 50 mm adjustable window: an external stop screw trims the extend stroke anywhere in the 70-120 mm range without changing the order. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper absorbs end-of-stroke energy at both ends, and 1/8" ports feed air filtered to 40 um across 0.15-1.0 MPa (22-145 psi). Note this unit has no magnet fitted; order the -S code if you need CMSE / 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 ACEJ80X120-50 Is Used
Bench press station
Delivers 2513.3 N at 0.5 MPa for riveting or staking aluminium brackets, with the stop screw set so the ram bottoms out at the exact part height.
Pallet gate actuator
Swings or lifts heavy conveyor gate sections in a warehouse line; the 70-120 mm trim range matches different gate stops without re-ordering cylinders.
Fixture clamp on a machining center
Clamps cast housings in a 4th-axis fixture where the short ISO 21287 body fits inside the fixture envelope, holding about 128 kg equivalent vertical load with margin.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-50 the Right Cylinder?
The stop screw is a mechanical end stop only, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads.
FA flange or LB foot mounts bolt to the ISO 21287 face, and I/Y rod knuckles suit swinging fixtures. The rod end here is female M12x1.75; add B to the code for a male thread. Sensing requires the optional -S magnet with CMSE / DMSE switches, and PT ports are standard with G available.
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 ACEJ80X120-50 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 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window: an external stop screw shortens the 120 mm extend stroke on site, giving a usable range of 70-120 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with 1/8" ports and a female M12x1.75 rod thread.
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 and fixed TPU bumpers at both ends. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face. Position sensing is not included: the magnet is the optional -S code, and only with it can CMSE / DMSE switches be mounted on the body slots.
