About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-30
The ACEJ80X125-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 125 mm stroke by up to 30 mm on site, giving a usable range of 95-125 mm without changing the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical maximum of 512.6 kgf at 1.0 MPa.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke energy, ports are 1/8" PT, speed spans 30-500 mm/s, and FA flange or LB foot mounts bolt straight to the ISO 21287 face. Note that the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding lock.

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 ACEJ80X125-30 Is Used
Pneumatic press station
A short-body 80 mm bore pushing 2513.3 N at 0.5 MPa suits bench-top forming and staking presses, and the 30 mm window lets one cylinder serve several part heights between 95 and 125 mm.
Weld fixture clamping
In automotive weld cells, the ISO 21287 face takes FA flange or LB foot mounts directly, and the compact body fits inside fixture framing where a full-profile cylinder would collide with clamps.
Pallet gate actuation
Conveyor gate and stopper arms in warehouse lines use the 2356.2 N pull stroke for positive retraction, with the TPU bumper quieting the gate at both ends of travel.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-30 the Right Cylinder?
If your fixture needs less than about 1500 N of working force, the 63 mm bore saves space and air; if you are near the limit, step up. Choose the -30 window only if your stroke genuinely varies within 95-125 mm - for a fixed stroke, the plain ACE 80X125 is simpler. The rod end here is female M12x1.75; add B to the code for a male thread. If you need position feedback, order the -S variant so CMSE / DMSE switches can ride the body - this model has no magnet fitted.
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 ACEJ80X125-30 FAQ
The ordered stroke is 125 mm and the -30 stop screw trims the extend stroke anywhere down to 95 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA, LB or FTC mounting plus I and Y rod knuckles. Sensors are not possible on this exact code because no magnet is fitted - order the -S version to get the optional magnet, then CMSE or DMSE switches can be clipped onto the body slots.
