Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-40
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-40 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-40
A double acting ISO 21287 compact cylinder, the ACEJ80X80-40 pairs an 80 mm bore with an 80 mm stroke that an external stop screw trims anywhere in a 40 mm window, giving a usable extend range of 40-80 mm. At 0.5 MPa it pushes with 2513.3 N and pulls with 2356.2 N, rising to 3518.6 N on push at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy jigs and press frames where a full-length body will not fit.
The hard-anodized aluminium body carries a 20 mm hard-chrome-plated S45C rod with a female M12x1.25 thread end, and 1/8" ports feed both chambers. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the optional -S magnet enables CMSE / DMSE switch sensing when ordered.

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 ACEJ80X80-40 Is Used
Short-stroke press station
With up to 3518.6 N at 0.7 MPa, it presses bearings or bushings into housings on an assembly line, trimming the extend stroke on site with the stop screw.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-40 the Right Cylinder?
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 or LB foot mountings bolt to the ISO 21287 face, and if position feedback matters, order the -S code so CMSE / DMSE switches can be 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 ACEJ80X80-40 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N and pull to 3298.7 N. The theoretical maximum at 1.0 MPa is 512.6 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and air filtered to 40 um.
An external stop screw shortens the 80 mm extend stroke by up to 40 mm on site, so the working range is 40-80 mm; it is an end stop only and never holds a load on air loss. The ISO 21287 compact body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends, FA/LB mounting options, a female M12x1.75 rod thread and 1/8" PT ports. Position sensing needs the optional -S magnet ordered with CMSE / DMSE switches.
