About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-40
A double acting ISO 21287 compact cylinder, the ACEJ100X80-40 pairs a 100 mm bore with an 80 mm stroke that an external stop screw trims on site by up to 40 mm, giving a usable extend range of 40-80 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. Keep real work to roughly 2356 N (about 0.6 of the push figure) and it will lift around 200 kg vertically with a 2:1 margin.
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 fits inside tight press frames and gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock, ports are 1/8" PT, the rod thread is female M12x1.75, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note the adjuster is a mechanical end stop only - on air loss the piston still drifts, so it never holds a load. The magnet is not fitted; order the -S code if you need CMSE / DMSE switching.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-40 Is Used
Press-frame stamping fixture
The 3927 N push at 0.5 MPa clinches aluminium brackets in a bench press, and the 40-80 mm adjustable window lets one cylinder serve several die heights without re-plumbing.
Heavy gate indexing on a machining line
Short body fits behind the machine guard where an ISO 15552 profile cylinder would not, cycling a 150 kg steel gate at 30-500 mm/s with the stop screw set to 60 mm.
Pallet clamp on a packaging cell
Pull force of 3769.9 N retracts a side-clamp arm against pallets; FA flange mounting bolts straight to the existing fixture face and the 1/8" PT ports suit standard plant air.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-40 the Right Cylinder?
At this bore size the step is wide: a 63 mm ACEJ delivers 1558.6 N push at 0.5 MPa, while the next step up is the 125 mm bore at 6135.9 N - so pick the 100 mm when your clamp or press load sits between roughly 1.6 kN and 4 kN. If the job needs a non-rotating rod or a through-rod, look at the TACE twin-guide or ACED double-rod variants instead. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for pivoting tooling, and remember to order the -S magnet code at purchase if CMSE / DMSE position sensing will be added later - it cannot be retrofitted.
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 ACEJ100X80-40 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: an external stop screw shortens the 80 mm extend stroke on site, so the usable range is 40-80 mm. It shortens only - it cannot lengthen the stroke past 80 mm, and it is a mechanical end stop, not a load-holding lock, so the piston drifts if air is lost.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Position sensing requires the optional -S magnet code ordered with the cylinder; this model has no magnet fitted, so no CMSE or DMSE switch can be mounted unless you specify -S. Mounting options include FA flange, LB foot and I/Y rod knuckles.
