About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-20
A double acting ISO 21287 compact cylinder, the ACEJ80X275-20 pairs an 80 mm bore with a 275 mm stroke that an external stop screw trims on site by up to 20 mm, giving a usable extend range of 255-275 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 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 simply will not fit.
The hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke shock at both ends, and 1/8" ports feed air at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.

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 ACEJ80X275-20 Is Used
Packaging line reject pusher
The short ISO 21287 body fits under guard rails where an ISO 15552 profile cylinder is too long, ejecting off-spec cartons at 30-500 mm/s from a 275 mm parked position.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-20 the Right Cylinder?
The stop screw shortens the extend stroke only - it never lengthens it past 275 mm - and it is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts, so add a separate valve or lock for load holding. FA flange or LB foot mountings bolt to the ISO 21287 face, and if you need position sensing, order the -S variant; this model has no magnet, so CMSE / DMSE switches cannot be fitted to it.
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 ACEJ80X275-20 FAQ
The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 275 mm extend stroke to any length from 255 to 275 mm. It is a mechanical end stop for the extend stroke only, not a mid-stroke lock or brake - on air loss the piston still drifts. Operating range is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod and fixed TPU bumpers at both ends. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this non-S model has no magnet, so no sensor can be mounted. FA flange and LB foot mountings plus I and Y rod knuckles bolt to the standard ISO 21287 face. Weight and outline dimensions: confirm from datasheet.
