About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-100
The ACEJ100X250-100 is a double acting, adjustable-stroke compact cylinder built to ISO 21287: a 100 mm bore pushes 3927 N and pulls 3769.9 N at 0.5 MPa, rising to 5497.8 N at 0.7 MPa. Its short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy clamping fits into tight presses and gantries. The 20 mm hard-chrome-plated S45C rod and fixed TPU bumpers at both ends handle end-of-stroke impact at speeds of 30-500 mm/s.
The -100 code gives a 100 mm adjustment window: an external stop screw trims the extend stroke anywhere between 150 and 250 mm on site, no disassembly needed. Note the stop is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding lock. For position feedback order the optional -S magnet, which enables CMSE / DMSE switches; without -S no magnet is fitted. Running 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, it lifts about 240 kg vertically at 0.5 MPa, or plan on roughly 2356 N of real work for margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-100 Is Used
Heavy press-fit and staking stations
3927 N at 0.5 MPa is enough to stake bearings or press bushings into housings, while the 100 mm window lets one cylinder serve several part heights from 150 to 250 mm.
Clamping on CNC machining fixtures
The short ISO 21287 body tucks inside fixture guards where an ISO 15552 profile cylinder would not fit, holding roughly 2356 N of practical clamping work at 0.5 MPa.
Pallet and die-lift actuators
Lifts about 240 kg vertically at 0.5 MPa with a 2:1 margin, so it suits die carts, lifters and heavy gate actuators on the 250 mm stroke.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X250-100 the Right Cylinder?
At 3927 N push at 0.5 MPa this 100 mm bore sits at the top of the ACEJ range; step down to 80 mm (2513.3 N) for lighter presses or to 125 mm (6135.9 N) when you need over 6000 N. Size the load at about 60% of rated push - roughly 2356 N of usable work - and remember the stop screw shortens the extend stroke only; it never holds a load mid-stroke. Bolt on FA flange or LB foot mounting plus I or Y rod knuckles to the ISO 21287 face, and add the -S code if CMSE / DMSE switching is planned. Female M12x1.75 rod thread, 1/8" PT ports, 250 mm stroke within a 300 mm max 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 ACEJ100X250-100 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 -100 code is a 100 mm adjustment window: an external stop screw trims the 250 mm extend stroke down to 150 mm on site. It is a mechanical end stop only - on air loss the piston drifts, so it does not hold a load. Ports are 1/8" PT, the rod thread is female M12x1.75, and speed runs 30-500 mm/s.
The ISO 21287 compact 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. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt straight to the standard face. Position sensing requires the optional -S magnet code - this model has no magnet fitted, so order -S to enable CMSE / DMSE switches.
