About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-20S
The ACEJ100X20-20S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 20 mm stroke anywhere within the ordered -20 window, giving a usable range of 0-20 mm without changing the cylinder. At 0.5 MPa the 100 mm bore delivers 3927 N push and 3769.9 N pull, rising to 5497.8 N push at 0.7 MPa - enough to lift about 400 kg vertically, or roughly 200 kg with a 2:1 margin. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and fixtures where a full-length body will not fit.
Construction is a hard-anodized aluminium body with an S45C hard-chrome plated rod, threaded aluminium covers and a fixed TPU bumper at each end to absorb end-of-stroke energy. This -S variant carries the optional magnet, so CMSE / DMSE reed or solid-state switches can be clamped anywhere along the body for end-of-travel signals. Air supply is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 1/8" port matches the 100 mm bore.

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 ACEJ100X20-20S Is Used
Short-stroke clamping press
The 0-20 mm adjustable window suits a stamping or riveting fixture that clamps a machined aluminium housing; 3927 N push at 0.5 MPa holds the part firmly through the cycle.
Pallet lift-and-lower post
With about 200 kg vertical lift capacity at a 2:1 margin, the 100 mm bore raises a loaded pallet plate on an assembly line, and the fitted magnet signals top of stroke via a DMSE switch.
Injection mold slide actuation
The compact body, about 50% shorter than an ISO 15552 profile cylinder, drives a mold slide inside a tight press guard, with the stop screw trimmed to match the exact slide travel.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-20S the Right Cylinder?
At this force class the 100 mm bore is the heavy hitter of the ACEJ range: 3927 N push at 0.5 MPa versus 2513.3 N for the 80 mm bore, while the 125 mm bore gives 6135.9 N if you need more. Plan on about 2356 N (roughly 240 kg) of real work at 0.5 MPa rather than the full rating. The stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, so on air loss the rod still drifts; use a valve or external clamp where position must be held. FA flange and LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches.
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 ACEJ100X20-20S 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 -20 code sets a 20 mm adjustment window: an external stop screw shortens the 20 mm extend stroke on site, so usable stroke is 0-20 mm. The stop is an end stop only - it never holds a load against air loss. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port 1/8".
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA flange or LB foot mounting options. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted along the body slots; models ordered without -S have no magnet.
