About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-10B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X125-10B pairs an 80 mm bore with a 125 mm stroke and a male rod thread (B code). At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The external stop screw trims the extend stroke by up to 10 mm on site, giving a usable range of 115-125 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, weld fixtures and gantries where a full-length body will not reach. The hard-anodized aluminium body carries a S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the optional -S magnet enables CMSE / DMSE switches; this unit has no magnet fitted.

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 ACEJ80X125-10B Is Used
Weld fixture clamping
The short ISO 21287 body fits inside weld cell tooling where a full-length profile cylinder cannot, clamping steel tube assemblies with about 1508 N of usable force at 0.5 MPa.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-10B the Right Cylinder?
If your load needs 115-125 mm of extend travel, the -10 window covers it; order a larger -NN window (20 to 100 mm) if the stroke may need more trimming later.
The male rod thread suits direct attachment to tooling plates and knuckles; FA flange, LB foot and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles are available. Remember the stop screw is a mechanical end stop only - on air loss the piston still drifts, so add a separate locking solution if position must be held. If sensing is needed, order the -S variant to enable CMSE / DMSE switches.
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 ACEJ80X125-10B 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 is 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 125 mm extend stroke on site, so the usable range is 115-125 mm. It never lengthens the stroke beyond 125 mm, and the stop is not a mid-stroke lock - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is 1/8" PT with a male rod thread.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and fixtures. A fixed TPU bumper at each end absorbs end-of-stroke energy. Mounting options include FA flange, LB foot and FTC brackets plus I and Y rod knuckles on the standard ISO 21287 face. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this model (no S code) has no magnet, so no sensor can be mounted on it. Non-standard strokes are made to order - confirm from datasheet.
