About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-100B
A double acting AirTAC compact cylinder in the heavy ISO 21287 class, the ACEJ80X275-100B pairs an 80 mm bore with a 275 mm stroke and a 100 mm adjustment window: an external stop screw trims the extend stroke on site anywhere between 175 and 275 mm, so one cylinder serves several fixture positions. 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 ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters on long-stroke gantries and press frames where every millimetre of envelope counts. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a male thread (B code), and the magnet is not fitted - order the -S code if you later need CMSE or DMSE switch positions.

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 ACEJ80X275-100B Is Used
Weld fixture clamping gantry
On automotive weld lines, the 275 mm stroke clamps deep fixtures while FA flange or LB foot mounting drops straight onto the ISO 21287 face; add the -S magnet code to feed CMSE or DMSE position signals to the PLC.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-100B the Right Cylinder?
If your tooling needs more than about 2500 N at 0.5 MPa, step up to the 100 mm bore; if 1500 N of usable force covers the job, the 63 mm saves space and air. Note that the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it must not be treated as a mid-stroke lock. FA flange or LB foot mounting bolts to the standard ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; without it there is no magnet in the piston.
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 ACEJ80X275-100B 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; the theoretical maximum is 512.6 kgf at 1.0 MPa. The -100 code is a 100 mm adjustment window: an external stop screw shortens the 275 mm extend stroke by up to 100 mm, giving a usable range of 175-275 mm. It is an end stop, not a load-holding brake - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits gantries and guards where a full-length cylinder will not. Mounting options include FA flange, LB foot and FTC brackets plus I and Y rod knuckles on the standard ISO 21287 face. Position sensing requires the optional -S magnet code - this model has no magnet fitted, so no CMSE or DMSE switch can be read until the -S version is ordered. The rod end is male thread (B code) and the air port is 1/8" PT.
