About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X90-50S
A double acting ISO 21287 compact cylinder, the ACEJ80X90-50S pairs an 80 mm bore with a 90 mm stroke that an external stop screw can trim anywhere in a 50 mm window, giving a usable extend range of 40-90 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on push 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, guarding and gantries where a full-length body will not fit.
The S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped into the body slots for end-of-stroke signalling. Ports are 1/8" PT, the rod is 20 mm with a female M12x1.25 thread, and speed runs 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 ACEJ80X90-50S Is Used
Fixture clamping on CNC machining centres
The 40-90 mm trim range lets one cylinder serve several fixture heights, and 2513.3 N at 0.5 MPa holds steel workpieces firmly during milling or drilling.
Short-stroke press and staking stations
With 3518.6 N available at 0.7 MPa, the 80 mm bore handles riveting, staking and light pressing on assembly lines where floor space is tight.
Vertical lift in packaging gantries
The compact body cuts mounting length by about half versus an ISO 15552 profile cylinder, and the fitted magnet with CMSE switches confirms top and bottom positions.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X90-50S the Right Cylinder?
Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the fitted -S magnet lets you add CMSE / DMSE switches wherever position feedback 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 ACEJ80X90-50S FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N, and the theoretical maximum is 512.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and a temperature range of -20 to +70 C. The extend stroke is adjustable from 40 to 90 mm via the stop screw within the ordered 50 mm window.
An external stop screw on the cylinder shortens the extend stroke by up to 50 mm, so you can set any extend length between 40 and 90 mm on site without changing the cylinder. Fixed TPU bumpers at both ends absorb end-of-stroke energy. Because this model carries the optional -S magnet, CMSE or DMSE reed and solid-state switches mount directly in the body slots. Mounting options include FA flange, LB foot and FTC brackets with I/Y rod knuckles.
