About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-30SB
The ACEJ80X40-30SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 40 mm stroke by up to 30 mm on site, giving a usable range of 10-40 mm without changing the cylinder. At 0.5 MPa the 80 mm bore delivers 2513.3 N on extend and 2356.2 N on retract, rising to 3518.6 N at 0.7 MPa - enough for heavy clamping and pressing fixtures. The male rod thread (B code) bolts straight into tooling, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight press frames and gantries where a full-length body will not reach. Fixed TPU bumpers absorb end-of-stroke energy at both ends, and the hard-anodized aluminium body with a hard-chrome S45C rod runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).

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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACEJ80X40-30SB Is Used
Fixture clamping on machining centres
Male rod thread and FA flange mounting let the 80 mm bore clamp heavy castings in 4th-axis fixtures, while the fitted magnet feeds a CMSE switch to the PLC.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-30SB 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 where a load must stay put. FA flange, LB foot and rod knuckles mount on the ISO 21287 face; PT ports and the male rod thread are standard on this variant.
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 ACEJ80X40-30SB FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N (pull 3298.7 N), with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 40 mm extend stroke by up to 30 mm, so the working range is 10-40 mm. It shortens the stroke only - it never extends past the ordered 40 mm.
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 variant carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for position signals. FA flange, LB foot and I/Y rod knuckles bolt straight to the standard mounting face, and fixed TPU bumpers at both ends absorb end-of-stroke shock.
