Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20SB
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20SB
A heavy-duty double acting compact cylinder built to ISO 21287, the ACEJ100X80-20SB pushes with 3927 N and pulls with 3769.9 N at 0.5 MPa - enough to index a full pallet of castings or clamp a large weldment without a bigger bore. The -20 code adds a 20 mm adjustment window: an external stop screw trims the 80 mm extend stroke down to 60 mm on site, so one cylinder serves several fixture depths.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 100 mm bore has to live inside a press frame or gantry. This unit carries the optional -S magnet, so CMSE / DMSE switches can be fitted for end-of-stroke signals, and the B code gives a male rod thread on the 20 mm rod.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 3770 N |
| 0.7 MPa | 5278 N |
| Max (@1.0 MPa) | 769 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20SB Is Used
Large weldment clamping
Roughly 240 kg of usable clamp force at 0.5 MPa holds heavy steel fabrications in fixtures where a full-length profile cylinder would not fit.
Press-frame ejection
The short ISO 21287 body drops into tight press frames, and the stop screw lets operators trim the 80 mm eject stroke without changing cylinders.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20SB the Right Cylinder?
Note that the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. Mount with FA flange or LB foot brackets on the ISO 21287 face; PT ports as standard, G on request.
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 ACEJ100X80-20SB FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa it pushes 5497.8 N and pulls 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: turn the external stop screw to shorten the 80 mm extend stroke anywhere down to 60 mm. The stop is an end stop only - it never holds a load if air pressure is lost.
It is an ISO 21287 compact cylinder whose body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome 20 mm rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots for extend and retract signals. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, 1/8" PT ports.
