About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-75S
The ACEJ80X120-75S is a double acting, adjustable-stroke compact cylinder built to ISO 21287: an 80 mm bore, a 120 mm stroke and a 20 mm hard-chrome-plated S45C rod, with a 1/8" port. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on the extend stroke at 0.7 MPa, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The -75 code means an external stop screw trims the extend stroke anywhere in a 75 mm window, giving a usable range of 45-120 mm without swapping the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy clamping fixtures and press heads where a full-length body will not fit. The magnet comes from the -S option this model carries, so CMSE or DMSE switches can be fitted for end-of-stroke sensing, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.

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 ACEJ80X120-75S Is Used
Weld fixture hold-down
The short ISO 21287 body tucks under weld-cell tooling where an ISO 15552 profile cylinder is too long, and CMSE switches confirm clamp closure on each cycle.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-75S the Right Cylinder?
Remember the stop screw sets the extend limit only - it is not a mid-stroke lock, so the rod will still drift if air is lost. If you need position sensing, keep the -S magnet code and pair it with CMSE or DMSE switches; choose FA flange or LB foot mounting to match the fixture face.
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 ACEJ80X120-75S 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. The -75 code gives a 75 mm adjustment window: an external stop screw shortens the 120 mm extend stroke on site, so the working range is 45-120 mm. It shortens the stroke only - it never extends it past 120 mm, and it is a mechanical end stop, not a load-holding lock.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel, threaded aluminium covers and a fixed TPU bumper at each end. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be slid into the body slots for position feedback. FA flange and LB foot mounts plus I and Y rod knuckles bolt to the standard ISO 21287 face; the rod end is a female M12x1.75 thread and the port is 1/8" PT.
