Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-20
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-20 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 ACEJ80X80-20
A double acting ISO 21287 compact cylinder, the ACEJ80X80-20 pairs an 80 mm bore with an 80 mm stroke that a stop screw trims on site by up to 20 mm, giving a usable extend range of 60-80 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) and rod speed 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into press fixtures and gantries where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers absorb end-of-stroke shock, and the optional -S magnet enables 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 ACEJ80X80-20 Is Used
Bottle-line ejector arm
On a beverage packaging line the 1/8" port feeds 30-500 mm/s ejection of rejected cartons, with FA flange mounting and the optional -S magnet feeding a DMSE switch for end-position confirmation.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-20 the Right Cylinder?
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 for suspended loads. FA flange and LB foot mountings bolt to the ISO 21287 face, and the rod ends in a female M12x1.75 thread. Order the -S code if CMSE / DMSE position sensing is needed; this version ships without a magnet.
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 ACEJ80X80-20 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, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 80 mm extend stroke to any length from 60 to 80 mm. It is an end stop only - it never holds a load on air loss. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C.
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 and fixed TPU bumpers at both ends. FA flange and LB foot mountings fit the standard face. Position sensing requires the optional -S magnet code; this model has no magnet fitted, so CMSE or DMSE switches can only be used on an -S version.
