About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-30B
The ACEJ80X80-30B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. The B code gives a male 20 mm rod thread, and the 1/8" port matches this bore size. The short hard-anodized aluminium body takes up roughly half the mounting length of an ISO 15552 profile cylinder, which is why it slots into presses and fixtures that cannot spare the depth.
The -30 code adds an external stop screw that trims the extend stroke anywhere from 50 mm to the full 80 mm, so one cylinder serves several die or fixture positions. A fixed TPU bumper at each end absorbs end-of-stroke shock, the S45C hard-chrome rod resists wear, and speeds of 30-500 mm/s cover fast cycling lines. Note that the stop screw sets the end position only; on air loss the piston still drifts, so it is not a mid-stroke lock.

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 ACEJ80X80-30B Is Used
Multi-height clamping gantry
The 50-80 mm adjustable range lets one gantry clamp castings of different heights without swapping cylinders between changeovers.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-30B the Right Cylinder?
The 30 mm window suits jobs where the final position is tuned on the machine, such as clamping different part heights. If you need position feedback, order the -S variant to enable CMSE / DMSE switches; this model has no magnet. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard ISO 21287 face.
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 ACEJ80X80-30B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code means an external stop screw shortens the 80 mm extend stroke by up to 30 mm, giving a usable range of 50-80 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C at 30-500 mm/s. The stop is an end stop only, not a load-holding brake.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for tight press beds and machine guards. It uses a hard-anodized aluminium body with an S45C hard-chrome-plated 20 mm rod, a male thread on this B version, and a fixed TPU bumper at both ends. Position sensing requires the optional -S magnet, which allows CMSE or DMSE switches; this model without the S code carries no magnet. FA flange, LB foot and FTC brackets mount on the standard face.
