About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-10
The ACEJ100X20-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 20 mm stroke by up to 10 mm on site, giving a usable range of 10-20 mm without changing the cylinder. At 0.5 MPa the 100 mm bore pushes 3927 N and pulls 3769.9 N, so this is the size for heavy clamping and pressing where every millimetre of envelope counts. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits into press frames and weld fixtures that cannot accept a full-length body.
In practice, plan for roughly 2356 N (about 240 kg) of real work at 0.5 MPa instead of the full 3927 N rating, and expect about 200 kg of vertical lift capability with a 2:1 margin. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with an M12x1.75 female thread, and 1/8" ports feed air at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s. Fixed TPU bumpers sit at both ends, and the magnet is the optional -S code: without it, no CMSE or DMSE switch can be mounted.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-10 Is Used
Press-frame clamping
The 3927 N push at 0.5 MPa clamps automotive stamping blanks inside a short press frame where a full-length ISO 15552 body cannot fit, with the 10 mm window fine-tuning clamp position per die.
Weld fixture hold-down
Body-shop fixtures use the 100 mm bore to hold steel panels through spot welding; the 10-20 mm adjustable range absorbs panel thickness variation without re-gapping the tooling.
Pallet gate actuation
Heavy pallet-stop gates on warehouse conveyor lines stroke just 20 mm; the compact body bolts between guide rails and the stop screw dials the gate travel down to 10 mm for narrow lanes.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-10 the Right Cylinder?
Size down if your load is light: a 63 mm bore gives 1558.6 N push at 0.5 MPa, while stepping up is rarely needed because the 100 mm bore already delivers 3927 N. Keep the stroke short here - if you need more than 20 mm of travel, order a longer stroke version (bore 100 accepts standard strokes up to 300 mm). The stop screw only shortens the extend stroke and is a mechanical end stop, not a load lock: on air loss the piston still drifts, so add a valve or external stop where holding matters. Match FA flange or LB foot mounts and I/Y rod knuckles to the ISO 21287 face, and add the -S code if CMSE / DMSE position sensing is planned.
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 ACEJ100X20-10 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N (pull 5277.9 N), with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 20 mm extend stroke by up to 10 mm, so usable travel is 10-20 mm. Air supply is 0.15-1.0 MPa (22-145 psi) through 1/8" ports, speed 30-500 mm/s, and the rod is 20 mm with an M12x1.75 female thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight press and fixture envelopes. Fixed TPU bumpers at both ends absorb end-of-stroke impact. Position sensing needs the optional -S magnet ordered with the cylinder; without it there is no magnet and no CMSE / DMSE switch can be read. FA flange and LB foot mounts bolt straight to the standard ISO 21287 face.
