About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-30S
The ACEJ100X250-30S is a double acting, adjustable-stroke compact cylinder built to ISO 21287. Its 100 mm bore delivers 3927 N push and 3769.9 N pull at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. An external stop screw trims the extend stroke anywhere within the 30 mm window, so the usable range is 220-250 mm without changing the valve or plumbing. The hard-anodized aluminium body and S45C hard-chrome plated 20 mm rod stand up to high-cycle industrial duty.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 250 mm stroke must fit inside a press frame, guard or gantry. In practice, plan on roughly 2356 N (about 240 kg) of real work at 0.5 MPa, and expect it to lift about 120 kg vertically with a 2:1 margin. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be clamped into the body slots for end-of-stroke sensing. Fixed TPU bumpers at both ends absorb end-of-stroke energy, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-30S Is Used
Press and forming fixtures
With 3927 N push at 0.5 MPa, the 100 mm bore clamps or presses steel brackets and bearing housings in assembly jigs, and the 220-250 mm adjustable range lets one cylinder serve several die heights.
Pallet and gate lifting
The bore lifts about 120 kg vertically with a 2:1 margin, enough for raising machine guards, lift gates and pallet stops on packaging lines where a full-length profile cylinder will not fit.
Heavy conveyor diverters
Pushing 3927 N at 0.5 MPa swings heavy diverters and stopper gates on bottling or warehouse conveyor lines, with CMSE switch feedback from the fitted -S magnet confirming each position.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-30S the Right Cylinder?
At this bore size the step is large: a 63 mm ACEJ pushes 1558.6 N at 0.5 MPa, so if your load needs more than about 1550 N of push, the 100 mm is the right class; the next step up is the 125 mm bore at 6135.9 N. Check that your air supply can sustain 0.5-0.7 MPa under flow, since the big bore consumes volume quickly at 30-500 mm/s. The stop screw is a mechanical end stop only - on air loss the piston still drifts, so add a separate locking solution if the load must be held. Order FA flange or LB foot mounting to bolt straight onto standard ISO 21287 fixtures, and remember the magnet here is the -S option this model already carries.
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 ACEJ100X250-30S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N and pull to 5277.9 N; theoretical maximum is 800.9 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 250 mm extend stroke by up to 30 mm, giving a usable range of 220-250 mm. It is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, with a fixed TPU bumper at each end.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 250 mm stroke fits where a full-length cylinder cannot. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for position feedback. FA flange and LB foot mountings bolt to the standard ISO 21287 face, and I or Y rod knuckles suit the 20 mm rod with its female M12x1.75 thread. Air supply is 1/8" port, fluid filtered to 40 um, temperature -20 to +70 C.
