About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-10B
The ACEJ80X120-10B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 120 mm stroke by up to 10 mm on site, giving a usable range of 110-120 mm. At 0.5 MPa the 80 mm bore delivers 2513.3 N on extend and 2356.2 N on retract, rising to 3518.6 N at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, guarding frames and gantries where a full-length body will not fit.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a male thread (B code), and the fixed TPU bumper at each end absorbs end-of-stroke energy. Air supply is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), and speed spans 30-500 mm/s. This unit has no magnet fitted; order the optional -S code if you later need CMSE / DMSE switch positions.

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 ACEJ80X120-10B Is Used
Pneumatic press station
The 2513.3 N extend force at 0.5 MPa suits a bench-top pressing fixture for bushings or bearings, with the 10 mm window letting you dial the 120 mm stroke down to the exact part height.
Injection mold slide gate
On a molding machine, the 110-120 mm adjustable stroke opens a slide gate just far enough for part clearance, and the 1/8" port keeps response fast at 30-500 mm/s.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-10B the Right Cylinder?
Size both ways before committing: the 63 mm bore pushes 1558.6 N at 0.5 MPa if your load is lighter, while the 100 mm bore reaches 3927.0 N for heavier clamping or lifting. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve where a load must stay put. FA flange and LB foot mountings bolt to the ISO 21287 face, and I/Y rod knuckles suit the male rod thread. If position feedback matters, specify the -S magnet variant instead of this no-magnet build.
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 ACEJ80X120-10B FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push reaches 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The bore is 80 mm, the stroke is 120 mm adjustable down to 110 mm via the stop screw, the rod is 20 mm with a male thread, the port is 1/8" PT, operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 30-500 mm/s.
An external stop screw shortens the extend stroke by up to 10 mm within the ordered -10 window, so the rod stops anywhere between 110 and 120 mm; it is a mechanical end stop, not a load-holding brake. This build has no magnet, so no switch can be mounted - order the optional -S magnet version to run CMSE / DMSE reed or solid-state switches. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.
