About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-30
The ACEJ100X55-30 is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 55 mm stroke that an external stop screw trims on site by up to 30 mm, giving a usable extend range of 25-55 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and machine frames where a full-length cylinder simply will not fit.
Plan on roughly 2356 N (about 240 kg) of real work at 0.5 MPa instead of the full rating, which means this unit lifts about 120 kg vertically with a 2:1 margin - enough for heavy pallet clamps or die carts. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the optional -S magnet code enables CMSE / DMSE switches; without -S no magnet is fitted.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-30 Is Used
Press-fit stamping fixture
With 3927 N push at 0.5 MPa and a 25-55 mm trimmed extend range, this cylinder presses bearings into housings on an automotive assembly line where the short body fits inside the press frame.
Pallet clamp on a transfer cart
The roughly 240 kg usable force at 0.5 MPa clamps heavy pallets against a stop, and the 30 mm adjustment window lets maintenance re-set the grip as pads wear.
Injection mould core insert
A 55 mm stroke trimmed down to 25 mm seats core inserts in a mould tool, with the 1/8" port keeping plumbing compact inside the tooling plate.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-30 the Right Cylinder?
At this force class the neighbours matter: the 80 mm bore pushes 2513.3 N at 0.5 MPa, while stepping up to 125 mm gives 6135.9 N, so pick the 100 mm when your load sits between roughly 1.5 and 2.4 kN of working demand. The stop screw only shortens the extend stroke and acts as an end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange or LB foot mountings bolt to the ISO 21287 face, and if you need position feedback order the -S magnet code so CMSE / DMSE switches 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 ACEJ100X55-30 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; theoretical maximum is 800.9 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 55 mm extend stroke by up to 30 mm, so the usable range is 25-55 mm. It cannot lengthen the stroke past 55 mm, and the stop is an end stop only - it never holds a load on air loss.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, a 20 mm hard-chrome S45C rod, a female M12x1.75 rod thread, a 1/8" PT port and a fixed TPU bumper at both ends. Speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Position sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; this model without -S has no magnet, so no sensor can be mounted.
