About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-30B
The ACEJ80X300-30B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 300 mm stroke by up to 30 mm, giving a usable range of 270-300 mm without changing the cylinder. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, and at 0.7 MPa push rises to 3518.6 N - enough for heavy clamping, pressing and lifting in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a male thread (the B code), and a fixed TPU bumper at each end absorbs end-of-stroke energy. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the magnet is the optional -S code - this unit has none, so CMSE / DMSE switches cannot be fitted unless -S is ordered.

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 ACEJ80X300-30B Is Used
Gate clamp on a foundry molding line
The male-threaded 20 mm rod drives sand-mold gate plates through a 270-300 mm stroke, with the fixed TPU bumper absorbing the stop at each end and LB foot mounting holding the cylinder rigid on the machine base.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-30B 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 if the load must stay put. FA flange or LB foot mounting bolts to the ISO 21287 face, and PT ports take standard fittings; order the -S code if position sensing will ever be needed.
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 ACEJ80X300-30B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 300 mm extend stroke on site, so the working range is 270-300 mm. It cannot lengthen the stroke past 300 mm, and the stop is not a load-holding brake - on air loss the piston drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a 20 mm hard-chrome S45C rod with male thread (B code) and 1/8" PT ports, plus a fixed TPU bumper at both ends. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, and FA flange or LB foot brackets bolt to the standard ISO 21287 face. Position sensing requires the optional -S magnet: this model has no magnet, so CMSE / DMSE reed or solid-state switches can only be used if you order the -S version.
