Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-20
The AirTAC Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-20 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-20
Double acting and built to ISO 21287 compact dimensions, the ACEJ100X20-20 pairs a 100 mm bore with a short 20 mm stroke that an external stop screw trims on site anywhere in a 0-20 mm window. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy clamping fits inside guards and press frames that a full-length body cannot enter.
Plan real work at roughly 2350 N (about 0.6 of the push rating), which supports around 240 kg of vertical load with margin. The hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke shock at both ends, and FA flange or LB foot mounts bolt to the standard ISO 21287 face. The magnet is not fitted on this code; order the optional -S version if CMSE / DMSE switch sensing is needed later.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ100X20-20 Is Used
Press-frame clamping
Short-stroke 3927 N push clinches steel brackets inside a compact welding press head where a 50%-longer profile body would not clear the frame.
Fixture ejection
The 0-20 mm adjustable window lets a CNC fixture eject machined housings the exact distance the part stop requires, tuned on site with the stop screw.
Pallet gate actuator
Drives a heavy pallet-line stop gate vertically, lifting about 240 kg of effective load with margin, mounted via LB feet under the conveyor rail.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X20-20 the Right Cylinder?
Size down to the ACEJ63 for lighter work (1558.6 N push at 0.5 MPa) or up to the ACEJ125 when you need 6135.9 N; this 100 mm bore covers the 3927 N middle ground at 0.5 MPa. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock, so the piston still drifts if air is lost. Female M12x1.75 rod thread and 1/8" PT ports suit standard tooling; add the -S code only if position sensing is required.
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 ACEJ100X20-20 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 -20 code is a 20 mm adjustment window: an external stop screw shortens the 20 mm extend stroke anywhere from 0 to 20 mm. It is an end stop only, not a load-holding lock, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends and FA flange, LB foot, FTC brackets plus I and Y rod knuckles fitting the standard face. This code has no magnet fitted, so no switch can be read; order the optional -S magnet to enable CMSE / DMSE reed or solid-state switches.
