About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-40
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X55-40 pairs an 80 mm bore with a 55 mm stroke and a 40 mm adjustment window. 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 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 external stop screw trims the extend stroke anywhere in the 15-55 mm range on site, so one cylinder serves several fixture positions without re-plumbing. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper sits at each end, and the optional -S magnet enables CMSE / DMSE switches when position feedback is needed.

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 ACEJ80X55-40 Is Used
Gantry clamp fixtures
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting clamp arms sit inside tight machine guards on CNC loading gantries.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-40 the Right Cylinder?
Remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange and LB foot mountings bolt to the ISO 21287 face, and the rod end here is a female M12x1.75 thread with a 1/8" PT port. Order the -S code if you need the magnet for CMSE / DMSE switches.
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 ACEJ80X55-40 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; theoretical maximum is 512.6 kgf at 1.0 MPa. The extend stroke is adjustable from 15 to 55 mm via the external stop screw (40 mm window). It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/8" PT port and female M12x1.75 rod thread.
The ISO 21287 compact construction uses a hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod and threaded aluminium covers, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy but never locks or holds a load. Sensing requires the optional -S magnet ordered with the cylinder; CMSE / DMSE switches then mount in the body slots. FA flange and LB foot mountings fit the standard ISO 21287 face.
