About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X50-30S
The ACEJ100X50-30S is a double acting AirTAC compact cylinder built to ISO 21287, with a 100 mm bore and a 50 mm stroke that an external stop screw can trim by up to 30 mm, giving a usable extend range of 20-50 mm. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N, rising to 5497.8 N at 0.7 MPa. The hard-anodized aluminium body carries magnet slots along its length, and the S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on anywhere in the stroke.
Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 100 mm bore slides into heavy clamping fixtures and press heads where a full-length cylinder will not fit. As a rule of thumb, plan on roughly 2356 N (about 240 kg) of real work at 0.5 MPa rather than the full rating; halved again for a 2:1 margin, it lifts about 200 kg vertically. A fixed TPU bumper at each end absorbs end-of-stroke shock, the S45C hard-chrome rod resists wear, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X50-30S Is Used
Heavy clamping fixtures
The 3927 N push at 0.5 MPa clamps large machined castings on CNC fixtures, and the 20-50 mm adjustable window lets one cylinder serve several part heights without re-plumbing.
Short-stroke press heads
With about 5500 N at 0.7 MPa, the 100 mm bore handles light staking and pressing of bushings and bearings, while the compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder in tight press frames.
Pallet lift-and-lower stations
The theoretical 800.9 kgf force class at 1.0 MPa suits lifting loaded pallets about 200 kg vertically with a 2:1 margin, and the fitted magnet with CMSE switches confirms top and bottom position.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X50-30S the Right Cylinder?
At this bore size the step either side is significant: a 80 mm bore gives 2513.3 N push at 0.5 MPa, while a 125 mm bore reaches 6135.9 N, so pick 100 mm when your fixture needs around 3900 N of push without jumping a frame size. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads. Mounting: FA flange or LB foot bolt to the ISO 21287 face, with I and Y rod knuckles available; the female M12x1.75 rod thread suits standard rod attachments. The fitted -S magnet means CMSE / DMSE switches work out of the box.
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 ACEJ100X50-30S FAQ
Push is 3927 N and pull is 3769.9 N at 0.5 MPa; 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 -30 code is a 30 mm adjustment window: an external stop screw shortens the 50 mm extend stroke by up to 30 mm, so the usable range is 20-50 mm. It shortens the stroke only and acts as an end stop, not a load-holding brake. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port 1/8" PT, rod thread female M12x1.75.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow press heads and gantries. A fixed TPU bumper at each end absorbs end-of-stroke impact. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted in the body slots for end-of-stroke or intermediate position signals. Mounting options include FA flange and LB foot, and non-standard strokes beyond the 300 mm maximum standard stroke for this bore are made to order.
