Airtac ACED Double-acting Compact Cylinder ACED125X30S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X30S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 30mm stroke, 1/4" 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 ACED Double-acting Compact Cylinder ACED125X30S
A heavy-duty double acting compact cylinder built to ISO 21287, the ACED125X30S pushes a 25 mm rod out of BOTH covers, so thrust is identical on every stroke: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal in both directions. At the 0.5 MPa rating that is a practical work figure of roughly 3534 N, or about 300 kg lifted vertically with a 2:1 margin - enough for clamping thick plate or raising a loaded fixture.
The hard-anodized aluminium body with a hard-chrome S45C rod keeps the short ISO 21287 footprint, saving about 50% of the mounting length of an ISO 15552 profile cylinder - useful when a 125 mm bore must fit inside a press frame or gantry. The -S magnet is fitted on this model, so CMSE / DMSE switches read position directly, and a fixed TPU bumper sits under each cover. Ports are 1/4" PT, the female rod thread is M16x2.0, and speed runs 30-500 mm/s over 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 (Ø125mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED125X30S Is Used
Press-frame part clinching
The 30 mm stroke and 5890.5 N at 0.5 MPa suit short-travel clinching or staking of brackets inside a compact press head, with equal force on the return stroke to strip the tool.
Gantry lift for heavy fixtures
A through-rod on both covers lets the 125 mm bore raise about 300 kg vertically with a 2:1 margin, guiding the load symmetrically without a separate guide column.
Position-verified weld clamps
With the fitted -S magnet, CMSE or DMSE switches confirm full clamp and full retract on automotive weld fixtures, where the short body fits between robot dress packs.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X30S the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N at 0.5 MPa both ways, one step up from the 100 mm bore (3769.9 N) if you need the extra clamp margin. If 3534 N of usable work at 0.5 MPa is more than the job needs, the 80 mm bore (2356.2 N) saves space and air. The 30 mm stroke is well inside the 300 mm standard for this bore. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot brackets bolt to the ISO 21287 face; the through-rod also resists rotation and can carry a sensor flag on the rear end.
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 ACED Double-acting Compact Cylinder ACED125X30S FAQ
Yes - the double-rod design puts a 25 mm rod through both covers, so both strokes use the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, identical push and pull, with a maximum of 1201.3 kgf at 1.0 MPa. Operating range 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, -20 to +70 C.
The hard-anodized aluminium body is a compact ISO 21287 build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits where a full-length cylinder cannot. A fixed TPU bumper at each cover absorbs end-of-stroke impact; it is not adjustable and does not hold a load. FA/FB flange or LB foot brackets mount on the standard face, and this -S model carries the magnet for CMSE / DMSE switches.
