Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-30B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-30B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 300mm 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 ACEJ100X300-30B
The -30 code adds a 30 mm adjustment window: an external stop screw trims the extend stroke anywhere between 270 and 300 mm on site, so one cylinder serves several fixture positions without re-ordering.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in long-stroke presses and gantries where every millimetre of envelope counts. The male rod thread (B code) suits external rod couplings, and CMSE / DMSE switches can be used only when the optional -S magnet is ordered - this unit has no magnet fitted.

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 ACEJ100X300-30B Is Used
Automotive fixture clamping
FA flange mounting and the male rod thread drop straight into standard ISO 21287 fixtures for clamping large castings on machining lines, with stroke trimmed on site via the stop screw.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-30B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, 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 mounting bolts to the ISO 21287 face, and PT ports are standard (order G for BSPP).
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 ACEJ100X300-30B FAQ
Push is 3927 N and pull is 3769.9 N at 0.5 MPa; at 0.7 MPa push rises to 5497.8 N and pull to 5277.9 N. Theoretical maximum force is 800.9 kgf at 1.0 MPa. It is double acting with a 30 mm adjustable extend window (usable stroke 270-300 mm), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits long-stroke machines with tight envelopes. The hard-anodized aluminium body carries a hard-chrome S45C rod with a male thread (B code) and 1/8" PT ports. Position sensing requires the optional -S magnet code: only then can CMSE or DMSE switches be mounted on the body slots. This model has no magnet fitted.
