About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X125-40
A double acting ISO 21287 compact cylinder, the ACEJ100X125-40 pairs a 100 mm bore with a 125 mm stroke that an external stop screw trims by up to 40 mm, giving a usable extend range of 85-125 mm on site. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, and at 0.7 MPa push rises to 5497.8 N, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s across -20 to +70 C.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy clamping can fit inside tight press frames and weld fixtures. Plan on roughly 2356 N of real work at 0.5 MPa, which lifts about 240 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the optional -S magnet enables CMSE / DMSE switches when ordered.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X125-40 Is Used
Press-frame clamping of steel stampings
With 3927 N push at 0.5 MPa and a 40 mm trim window, the cylinder clamps heavy stampings in a compact press frame where a full-length ISO 15552 body would not fit.
Pallet-lift pop-up rollers in warehousing
The short body and about 240 kg vertical-lift margin at 0.5 MPa suit pop-up roller stations that raise loaded pallet sections on conveyor transfer lines.
Gate actuation on foundry sand lines
A 125 mm stroke trimmed to 85-125 mm drives sand-gate slides on moulding lines, with the optional -S magnet feeding CMSE switch feedback to the PLC.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X125-40 the Right Cylinder?
At this force class the 100 mm bore is the right pick when a 63 mm bore (1558.6 N push at 0.5 MPa) falls short but an 80 mm bore (2513.3 N) leaves little margin for your 3927 N-class load. If your job needs a longer reach, bore 100 accepts standard strokes up to 300 mm, so a 125 mm stroke sits well inside the catalogue range. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve where a load must stay put. Bolt FA flange or LB foot mounts to the ISO 21287 face, and order 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 ACEJ100X125-40 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: a stop screw on the front cover shortens the 125 mm extend stroke by up to 40 mm, so the working range is 85-125 mm. It shortens the stroke only and never extends it past the ordered value.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, an S45C hard-chrome rod, a 1/8" PT port and a fixed TPU bumper at both ends that absorbs end-of-stroke impact. Mounting options include FA flange and LB foot plus I/Y rod knuckles on the standard ISO 21287 face. Position sensing requires the optional -S magnet code; without it no magnet is fitted, so CMSE / DMSE switches only work when -S is ordered.
