About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-30
The ACEJ80X35-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 35 mm stroke down by up to 30 mm on site, giving a usable range of 5-35 mm without changing the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke energy, the 1/8" port takes standard PT fittings, and FA flange or LB foot mounts bolt straight onto the ISO 21287 face. Note that the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding brake.

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 ACEJ80X35-30 Is Used
Welding fixture clamping
The 5-35 mm adjustable range lets a jig builder dial in exact clamp contact on steel brackets, with the stop screw set once during commissioning.
Compact forming module
A body about 50% shorter than an ISO 15552 profile cylinder fits into tight machine frames for light crimping and forming of sheet-metal parts.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-30 the Right Cylinder?
The 30 mm adjustment window suits stations where the final position is tuned during commissioning, such as setting clamp contact on a welding fixture. If the load must stay put on air loss, add an external locking device - the stop screw only limits the extend stroke. Order the -S code if you later need CMSE / DMSE switches; this version has no magnet fitted.
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 ACEJ80X35-30 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 is 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 35 mm extend stroke by up to 30 mm, so the working range is 5-35 mm. It shortens the stroke only - it never extends it past 35 mm - and it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. Operating pressure is 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, on air filtered to 40 um.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and a fixed TPU bumper at both ends. FA flange and LB foot mounts bolt directly to the ISO 21287 face, and the rod end is female M12x1.75 with a 1/8" PT port. Position sensing requires the optional -S magnet code: this ACEJ80X35-30 has no magnet fitted, so CMSE or DMSE switches can only be used if you order the -S version.
