About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40
A heavy-duty double acting compact cylinder built to ISO 21287, the ACEJ100X300-40 pairs a 100 mm bore with a 300 mm stroke and an external stop screw that trims the extend stroke by up to 40 mm on site, giving a usable range of 260-300 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, and the hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod stands up to continuous jig and gantry work. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length body cannot.
In practice that 3927 N push means you can plan on roughly 2350 N (about 240 kg) of real working force at 0.5 MPa, or lift about 200 kg vertically with a 2:1 margin. The fixed TPU bumper at each end absorbs end-of-stroke energy, speed spans 30-500 mm/s, and the air supply runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating. FA flange and LB foot mounts bolt to the standard ISO 21287 face, and the female M12x1.75 rod thread accepts standard rod knuckles.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40 Is Used
Pallet stamping press head
The 3927 N push at 0.5 MPa drives a marking or stamping head on pallet lines, and the 260-300 mm adjustable range lets technicians dial the stroke to the pallet height without swapping cylinders.
Vertical lift in a machine frame
With about 200 kg of vertical lift capacity at a 2:1 margin, the 100 mm bore raises heavy fixtures inside a compact gantry where the short ISO 21287 body saves roughly half the mounting length of an ISO 15552 profile cylinder.
Heavy gate pusher on a transfer line
The 3769.9 N pull at 0.5 MPa retracts a sliding gate or diverter against load, with the 1/8" port feeding high flow for the 30-500 mm/s speed band.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-40 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 the 100 mm is the right pick when your load sits between roughly 1600 N and 6000 N. Size the stroke first, then order the -40 window only if your fixture needs on-site trimming between 260 and 300 mm; the stop screw shortens the extend stroke, it never lengthens it. Note the adjuster is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. If you need position feedback, order the -S variant, because this code has no magnet and no CMSE or DMSE switch can be fitted.
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 ACEJ100X300-40 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N and pull to 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The ordered stroke is 300 mm and the -40 stop screw trims the extend stroke down to 260 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port 1/8", rod thread female M12x1.75.
The ISO 21287 short body uses a hard-anodized aluminium barrel with threaded aluminium covers, a hard-chrome plated S45C rod and a fixed TPU bumper at each end that only decelerates at stroke ends. FA flange and LB foot mounts fit the standard face. Position sensing requires the optional -S magnet code, which enables CMSE or DMSE switches; this model without -S carries no magnet.
