Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-75
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-75 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 125mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-75
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X125-75 pairs an 80 mm bore with a 125 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 ceiling of 512.6 kgf at 1.0 MPa. The external stop screw shortens the extend stroke on site anywhere in that 75 mm window, so one cylinder covers 50-125 mm of travel without reordering.
The hard-anodized aluminium body and S45C hard-chrome rod keep the short frame durable, and the body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside presses, weld fixtures and gantries where every millimetre counts. FA flanges and LB feet bolt to the standard ISO 21287 face, and the fixed TPU bumpers absorb end-of-stroke shock at both ends.

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 ACEJ80X125-75 Is Used
Short-stroke pressing
With 3518.6 N available at 0.7 MPa, this bore handles light staking, riveting and bearing seating on electronics and small-motor assembly lines where a full-length cylinder will not fit.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-75 the Right Cylinder?
If the machine must hold position through a power loss, add an external locking unit, because the stop screw only sets the extend limit and the piston will drift on air loss. Order the -S code if you need the optional magnet for CMSE / DMSE switches; this model ships without a magnet. Female M12x1.75 rod thread and 1/8" PT ports suit standard 80 mm bore plumbing.
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 ACEJ80X125-75 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, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -75 code sets a 75 mm adjustment window: an external stop screw trims the extend stroke anywhere between 50 and 125 mm. The stop is a mechanical end limit only, so the piston still drifts if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi) at 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 shallow fixtures and guarded cells. 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 CMSE or DMSE switches can only be used if you order the -S variant.
