About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X100-40
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ100X100-40 pairs a 100 mm bore with a 100 mm stroke and a 40 mm trim window. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N, rising to 5497.8 N on the extend side at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. An external stop screw shortens the extend stroke on site anywhere within the ordered 40 mm window, so the same cylinder covers a 60-100 mm working range without re-plumbing. Speeds run 30-500 mm/s across a 0.15-1.0 MPa (22-145 psi) supply.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in heavy presses and gantries where every millimetre of envelope counts. For sizing, plan on roughly 0.6 of the push force, about 2360 N of real work at 0.5 MPa, and note the vertical-lift equivalent: 3927 N over 9.81 is about 400 kg, so halve that for a 2:1 margin and it lifts about 200 kg vertically. The hard-anodized aluminium body carries a S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the optional -S magnet enables CMSE / DMSE switches when ordered.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X100-40 Is Used
Clamping fixtures on CNC machining centres
The 3927 N push at 0.5 MPa clamps large aluminium or cast-iron workpieces in machining fixtures, and the 40 mm trim window lets one cylinder serve several fixture sizes between 60 and 100 mm of stroke.
Bench press and staking stations
With about 2360 N of usable work force at 0.5 MPa, this bore handles staking, riveting and light pressing of bushings and bearings on assembly benches at 30-500 mm/s.
Vertical lift in palletising gantries
The vertical-lift equivalent of the push force is about 400 kg, so with a 2:1 margin it raises roughly 200 kg packages or trays in gantry pick-and-place heads where the short body fits the Z-axis frame.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X100-40 the Right Cylinder?
At this bore size the step either way is large: a 63 mm bore delivers 1558.6 N push at 0.5 MPa, while a 125 mm bore reaches 6135.9 N, so choose the 100 mm when your load sits between roughly 1500 N and 4000 N. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads.
FA flange or LB foot mounts bolt straight to the ISO 21287 face, and I / Y rod knuckles suit pivoting tooling. If position feedback is needed, order the -S code; without it there is no magnet and no CMSE / DMSE sensing. Port is 1/8" PT, rod end is female M12x1.75, and strokes up to 300 mm are standard for this bore.
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 ACEJ100X100-40 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N, and the theoretical maximum is 800.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 100 mm extend stroke on site to any setting from 60 to 100 mm. It is a mechanical end stop only, so it never locks or holds a load if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight press frames and gantry carriages. FA flange and LB foot mounts plus I / Y rod knuckles bolt to the standard face, the air port is 1/8" PT and the rod end is female M12x1.75. Position sensing requires the optional -S magnet ordered with the cylinder; only then can CMSE / DMSE switches be mounted on the body slots.
