About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-50
The ACEJ80X275-50 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 275 mm stroke by up to 50 mm, giving a usable range of 225-275 mm on site. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical maximum of 512.6 kgf at 1.0 MPa. Air filtered to 40 um drives it across 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 275 mm stroke fits where a full-length body would not. The hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke energy, 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 ACEJ80X275-50 Is Used
Pallet lift-and-lower stations
Raises and lowers loaded pallets of roughly 90 kg at a conveyor transfer point, with the compact body fitting the short gap under the deck.
Press-fit ejection
Ejects housings or bearings from assembly press tooling, trimming the 275 mm stroke down to 225 mm so the ejector face stops exactly at die level.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-50 the Right Cylinder?
Remember the stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a mid-stroke lock for holding a suspended load. Bolt FA flange or LB foot mounts to the ISO 21287 face, choose female M12x1.75 rod thread (add B for male), and order the -S code if position sensing with CMSE / DMSE switches is needed.
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 ACEJ80X275-50 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N; theoretical maximum is 512.6 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 275 mm extend stroke, so the working range is 225-275 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 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 20 mm rod and fixed TPU bumpers at both ends. FA flange and LB foot mounts bolt to the standard face. Position sensing requires the optional -S magnet code; this model has no magnet fitted, so order ACEJ80X275-50S to use CMSE / DMSE switches.
