Airtac ACED Double-acting Compact Cylinder ACED125X35
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X35 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 35mm 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 ACED125X35
The ACED125X35 is a double acting, double-rod compact cylinder built to ISO 21287: a 125 mm bore with a 25 mm hard-chrome-plated S45C rod leaving BOTH covers, so thrust is identical on the extend and retract strokes. At 0.5 MPa it delivers 5890.5 N in either direction (8246.7 N at 0.7 MPa), and the through-rod resists rotation and side load while the rear rod can carry a sensor flag or a second tool. The 35 mm stroke keeps the whole unit short enough for heavy clamping where travel is minimal.
The hard-anodized aluminium body with roller-burnished bore saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits deep press platens and guarded weld stations. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the short body means a 300 mm standard-stroke family drops into standard fixtures. As a working rule, budget roughly 3534 N (about 360 kgf) of that 0.5 MPa rating for real work - with a 2:1 margin it lifts about 180 kg vertically.

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 ACED125X35 Is Used
Press platen clamping
The 5890.5 N bidirectional thrust at 0.5 MPa clamps steel weldments on both strokes of a short 35 mm press platen, with the TPU bumpers absorbing the strike at each end.
Heavy pallet pusher
A warehouse pallet diverter uses the through-rod to push and retract full 180 kg loads symmetrically, the double rod keeping the pusher plate square under side load.
Die car positioning
On a stamping line the rear rod carries a flag for a CMSE switch (order the -S magnet) to confirm die-car lockout, while the front rod seats the car against the bolster.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X35 the Right Cylinder?
At 125 mm bore this is near the top of the ACED range: 5890.5 N per direction at 0.5 MPa versus 3769.9 N for the 100 mm bore, while the 80 mm bore gives 2356.2 N if your load is lighter. Step down only after checking that 2356 N covers the job. 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. Mounting is via FA/FB flange, LB foot or FTC brackets with I/Y rod knuckles on the ISO 21287 face; ports are 1/4" (PT thread, G on request) and the female M16x2.0 rod thread suits standard rod eyes. Position feedback needs the optional -S magnet code - without it no CMSE / DMSE switch can be 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 ACED Double-acting Compact Cylinder ACED125X35 FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, 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, temperature -20 to +70 C, bore 125 mm, rod 25 mm, stroke 35 mm, 1/4" PT port and female M16x2.0 rod thread.
The hard-anodized aluminium body with threaded covers saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end decelerates the piston - it does not hold or brake a load, so use a rod lock or pilot check for load holding. FA/FB flange, LB foot and FTC brackets plus I/Y knuckles bolt to the ISO 21287 face. For CMSE / DMSE switches order the optional -S magnet version; this model without the S code carries no magnet.
