About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-10
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X120-10 pairs an 80 mm bore with a 120 mm stroke and a 10 mm trim window: an external stop screw shortens the extend stroke on site anywhere within 110-120 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, so it sits in the heavy-thrust class of the ACEJ range. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it lands in presses, clamping fixtures and gantries too tight for a full-length body.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome-plated rod, and a fixed TPU bumper at each end absorbs end-of-stroke energy. Because the adjuster is a mechanical end stop rather than a mid-stroke lock, the piston still drifts if air is lost, so do not rely on it to hold a load. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the rod ends in a female M12x1.75 thread.

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 ACEJ80X120-10 Is Used
Clamping fixture on a machining centre
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting the 120 mm stroke clamp workpieces inside guarded fixtures where a full-length body will not fit.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-10 the Right Cylinder?
Size against neighbours: the 63 mm bore pushes 1558.6 N at 0.5 MPa while the 100 mm bore reaches 3927.0 N, so the 80 mm is the middle step when 63 mm runs out of thrust but 100 mm is oversized. The 120 mm stroke sits well inside the 300 mm maximum standard stroke for this bore. Choose the LB foot or FA flange to bolt into standard ISO 21287 fixtures, and add I or Y rod knuckles for side-swing linkage. If you need position feedback, order the -S variant for the optional magnet that enables CMSE / DMSE switches; this base model has no magnet fitted.
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 ACEJ80X120-10 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, and temperature -20 to +70 C. The extend stroke is adjustable from 110 to 120 mm via the external stop screw (10 mm window).
The -10 code sets a 10 mm adjustment window: turn the external stop screw to shorten the 120 mm extend stroke anywhere down to 110 mm. The fixed TPU bumpers at both ends only decelerate the piston at the ends of travel; they never lock or hold a load, and the rod still drifts on air loss. For position sensing, order the -S code for the optional magnet, which enables CMSE or DMSE switches; this base model has no magnet, so no switch can be mounted.
