About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40S
The ACEJ100X300-40S is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 300 mm stroke that an external stop screw trims by up to 40 mm, giving a usable extend range of 260-300 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. As a rule of thumb, plan for about 2356 N of real work at 0.5 MPa, which lifts roughly 120 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 a 300 mm stroke fits where a full-length body will not. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for end-of-stroke sensing. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the female M12x1.75 rod thread with a 1/8" PT port keeps plumbing straightforward.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3770 N |
| 0.7 MPa | 5498 N | 5278 N |
| Max (@1.0 MPa) | 801 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40S Is Used
Baling press pre-clamp
With 3927 N push at 0.5 MPa and a 260-300 mm adjustable extend range, the cylinder positions bales in a recycling baler before the main ram closes, and CMSE switches confirm full extension via the fitted magnet.
Pallet gate actuator
The short ISO 21287 body swings a heavy pallet-stop gate on a warehouse conveyor line, where about 120 kg of vertical lift equivalent at 0.5 MPa covers the gate weight with margin.
Foundry mold positioner
In a sand-casting line, the 100 mm bore pushes mold boxes against a locating stop at 30-500 mm/s, and the 40 mm stop-screw window lets technicians trim the 300 mm stroke to the fixture without changing cylinders.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40S the Right Cylinder?
Size against the load: the 80 mm bore delivers 2513.3 N push at 0.5 MPa, while stepping up to the 125 mm bore gives 6135.9 N. If your clamp or press needs between those figures, the 100 mm bore at 3927 N push is the match. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position.
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 ACEJ100X300-40S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 300 mm extend stroke on site, so the usable range is 260-300 mm. It cannot lengthen the stroke past 300 mm, and the stop is not a load-holding lock. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 300 mm stroke fits tight gantries and guards. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for position feedback. FA flange and LB foot mountings bolt straight to the standard face, the rod end is female M12x1.75, the air port is 1/8" PT, and fixed TPU bumpers at both ends absorb end-of-stroke energy.
