About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-100B
A double acting ISO 21287 compact cylinder, the ACEJ80X125-100B pairs an 80 mm bore with a 125 mm stroke that an external stop screw trims down by up to 100 mm, giving a usable extend range of 25-125 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body carries magnet slots, and the S45C rod is hard-chrome plated with a male thread (B code) on the end.
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 cannot. A fixed TPU bumper at each end absorbs end-of-stroke impact, speeds run 30-500 mm/s, and the port is 1/8" PT. Note there is no magnet fitted unless you order the optional -S code for CMSE / DMSE switches.

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 ACEJ80X125-100B Is Used
Weld fixture clamping
The 80 mm bore holds about 150 kgf of usable clamp force on automotive weld jigs, and the short body fits inside fixture framing that a full-length profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-100B the Right Cylinder?
Remember the stop screw only shortens the extend stroke within the 100 mm window - it is a mechanical end stop, not a mid-stroke lock, so the rod can drift if air is lost. FA flange, LB foot and rod knuckles bolt to the ISO 21287 face; add the -S code if CMSE / DMSE position sensing is needed.
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 ACEJ80X125-100B FAQ
The -100 code is a 100 mm adjustment window: an external stop screw shortens the 125 mm extend stroke on site, so the working range is 25-125 mm. It shortens the stroke only - it never extends past 125 mm and does not lock the load if air is lost.
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, 1/8" PT ports and fixed TPU bumpers at both ends. Sensing is not fitted as standard: order the optional -S magnet version to enable CMSE / DMSE switches; without -S there is no magnet and no switch can be read.
