About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-75
A double acting ISO 21287 compact cylinder with a 100 mm bore and a 120 mm stroke that can be trimmed on site. The -75 code gives a 75 mm adjustment window: an external stop screw shortens the extend stroke anywhere in the 45-120 mm range, so one cylinder covers several jig positions without re-ordering. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters on wide presses and gantries where every millimetre of envelope counts.
For sizing, plan on roughly 2356 N (about 240 kg) of real work at 0.5 MPa instead of the full rating, and expect it to lift about 200 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the female M12x1.75 rod thread with a 1/8" PT port keeps plumbing simple. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note that this unit has no magnet fitted; the optional -S code is what enables CMSE / DMSE switches.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-75 Is Used
Baling and compacting station
The 3927 N push at 0.5 MPa (5497.8 N at 0.7 MPa) suits a scrap or packaging baler where the 75 mm window lets operators dial the press platen between 45 and 120 mm for different bale sizes.
Pallet clamp on a conveyor transfer
With about 200 kg of vertical lift capability at a 2:1 margin, the cylinder can hold a loaded pallet clamp on an automated line, and the short body fits the tight space beside the chain.
Gate actuator on a foundry ladle line
In hot, dusty foundry surroundings the -20 to +70 C range and hard-anodized body cope with the environment, and the 45-120 mm adjustable stroke matches interchangeable mould-carrier gates.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-75 the Right Cylinder?
At this force class, compare downward: a 63 mm bore delivers 1558.6 N push at 0.5 MPa, so if your load is under about 900 N of real work the smaller bore saves air and money. Step up only if you need more than the 100 mm bore's 3927 N push. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange or LB foot mounts bolt to the ISO 21287 face, and if you need position feedback, order the -S magnet variant so CMSE / DMSE switches can be clipped on.
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 ACEJ100X120-75 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. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 120 mm extend stroke, giving a usable range of 45-120 mm. It trims the stroke only - it never lengthens it past 120 mm, and it is a mechanical end stop, not a load-holding brake. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and a fixed TPU bumper at each end absorbs end-of-stroke shock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames. FA flange and LB foot mounts bolt straight to the standard face. For switching, order the optional -S magnet version - this model code has no magnet, so CMSE / DMSE reed or solid-state switches can only be used when -S is specified at order time. Rod end is female M12x1.75 and the air port is 1/8" PT.
