About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-10
The ACEJ100X250-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 250 mm stroke by up to 10 mm on site, giving a usable range of 240-250 mm without changing the order. At 0.5 MPa the 100 mm bore pushes 3927 N and pulls 3769.9 N, rising to 5497.8 N push at 0.7 MPa, so it carries heavy clamp and press loads in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
For sizing, plan on roughly 2356 N (about 240 kg of thrust) of real work at 0.5 MPa, which is about 60% of the rated push; halved again for a 2:1 margin that is around 120 kg lifted vertically. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and FA flange or LB foot mounts bolt to the standard ISO 21287 face. This unit has no magnet fitted - order the optional -S code if CMSE / DMSE switch sensing is needed.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3770 N |
| 0.7 MPa | 5498 N | 5278 N |
| Max (@1.0 MPa) | 801 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-10 Is Used
Heavy fixture clamping
Clamps large machined castings on CNC fixtures where the 3927 N push at 0.5 MPa holds the part and the 240-250 mm adjustable range matches varied fixture heights.
Press and forming stations
Light forming, riveting and marking heads on assembly lines, using the 5497.8 N push at 0.7 MPa and the compact body to fit inside guarded machine frames.
Pallet stop and gate actuation
Stops, gates and diverters on pallet conveyors, where the 250 mm stroke moves heavy loads and the short ISO 21287 body fits between conveyor frames.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-10 the Right Cylinder?
At this bore size the step either way is large: the 80 mm bore delivers 2513.3 N push at 0.5 MPa while the 125 mm bore reaches 6135.9 N, so pick the 100 mm when your load sits between roughly 2400 and 6000 N. Remember the stop screw is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve where a load must stay put. FA flange and LB foot mountings plus I/Y rod knuckles fit the standard face, and the optional -S magnet enables 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 ACEJ100X250-10 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull 5277.9 N; theoretical maximum is 800.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, and the 1/8" port suits the 100 mm bore.
The -10 code is a 10 mm window: a stop screw at the extend end shortens the 250 mm stroke to as little as 240 mm, and a fixed TPU bumper decelerates at both ends. This unit has no magnet, so no switch can be read from it - order the optional -S magnet version to run CMSE / DMSE reed or solid-state switches. FA flange and LB foot mounts bolt to the ISO 21287 face, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
