About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X90-20S
The ACEJ100X90-20S is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 90 mm stroke that an external stop screw can trim anywhere in a 20 mm window, giving a usable extend range of 70-90 mm. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N, rising to 5497.8 N on the extend stroke at 0.7 MPa. Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this force class drops into gantries and press fixtures that cannot accept a full-length body.
For practical sizing, treat roughly 0.6 of the push rating as the working figure, so about 2356 N of real force at 0.5 MPa; that corresponds to lifting about 240 kg vertically, or roughly 120 kg with a 2:1 margin. The S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slot for end-of-stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod stands up to continuous production duty.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X90-20S Is Used
Clamping on CNC machining fixtures
The 3927 N push at 0.5 MPa clamps steel housings on milling fixtures, and the 70-90 mm adjustable extend range lets one fixture family handle parts of slightly different heights without re-plumbing.
Press-fit of bearings into pump housings
With about 2356 N of usable working force at 0.5 MPa, this cylinder presses small bearings and bushings into pump or motor housings on assembly benches where a full-length profile body would not fit.
Lifting gate on pallet conveyor stops
The bore 100 class lifts about 240 kg vertically at 0.5 MPa, enough to raise heavy pallet-stop gates on warehouse conveyor lines, with CMSE switches confirming up and down positions.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X90-20S the Right Cylinder?
At this bore size the step either side is large: a 80 mm ACEJ delivers about 2513 N push at 0.5 MPa while a 125 mm bore reaches 6135.9 N, so pick the 100 mm when your clamp or press load sits between roughly 1400 and 2350 N of working force. Note that the stop screw only shortens the extend stroke and acts as a mechanical end stop; it does not lock the piston mid-stroke, so on air loss the rod will drift and a separate holding valve is needed for suspended loads.
FA flange or LB foot mounts bolt to the standard ISO 21287 face, and I or Y rod knuckles suit swinging linkages. The fitted -S magnet pairs with CMSE / DMSE switches, and the 1/8" port keeps air supply adequate for the 30-500 mm/s speed range at 0.15-1.0 MPa (22-145 psi).
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 ACEJ100X90-20S FAQ
At 0.5 MPa the cylinder pushes with 3927 N and pulls with 3769.9 N; at 0.7 MPa those rise to 5497.8 N push and 5277.9 N pull, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 20 mm, so the working range is 70-90 mm. It cannot lengthen the stroke beyond 90 mm, and the stop is not a mid-stroke lock - the rod still drifts if air is lost.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and gantries. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount in the body slots for position feedback. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face, the rod end is female M12x1.75, the port is 1/8" PT, and a fixed TPU bumper at each end absorbs end-of-stroke energy.
