About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-75
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X275-75 pairs an 80 mm bore with a 275 mm stroke and a 75 mm trim window. 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 peak of 512.6 kgf at 1.0 MPa. The external stop screw shortens the extend stroke on site anywhere in the 200-275 mm range, so one cylinder can serve several fixture positions without re-ordering. A fixed TPU bumper at each end absorbs end-of-stroke shock.
The hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod and 1/8" ports. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into deep presses and long-stroke gantries that a full-length body cannot reach. FA flange and LB foot mounts bolt straight to the ISO 21287 face. The magnet is the optional -S code; this version has none, so CMSE / DMSE switches cannot be fitted unless you order -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 ACEJ80X275-75 Is Used
Pallet strapping station
A packaging line uses the 275 mm stroke to reach down over a pallet load, with the stop screw set so the compression plate lands at a fixed depth for each carton size.
Injection mould part ejector
Mounted LB-foot under a mould tool, the cylinder kicks large housings off the ejector plate; the trimmed stroke prevents overtravel that would mark the part surface.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-75 the Right Cylinder?
If your part weight needs more than about 153 kg of vertical lift at 0.5 MPa, step to bore 100. Remember the stop screw only trims the extend stroke and is not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve for suspended loads. Choose FA flange or LB foot mounting, female M12x1.75 rod thread as ordered or the B male option, and add -S to the code if CMSE / DMSE position sensing is planned.
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 ACEJ80X275-75 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 -75 code is a 75 mm adjustment window: an external stop screw shortens the 275 mm extend stroke by up to 75 mm, giving a usable range of 200-275 mm. It is a mechanical end stop only, not a load-holding brake, and the piston drifts if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits long-stroke machines where space is tight. It has a hard-anodized aluminium body, S45C hard-chrome rod, fixed TPU bumpers at both ends and 1/8" ports. Sensors work only with the optional -S magnet code: order ACEJ80X275-75S and CMSE / DMSE switches can ride the body slots. This non-S version has no magnet, so no switch can be mounted on it.
