Airtac ACED Double-acting Compact Cylinder ACED125X225
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X225 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 225mm 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 ACED125X225
A heavy-duty double acting compact cylinder, the ACED125X225 pushes a 125 mm bore through a 225 mm stroke and delivers 5890.5 N at 0.5 MPa in BOTH directions, because a rod exits each cover and both strokes work on the rod-side area. At 0.7 MPa that rises to 8246.7 N either way, with a peak of 1201.3 kgf at 1.0 MPa. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tool.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 225 mm stroke fits deep slides and gantry Z-axes without eating machine length. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body runs on a hard-chrome S45C rod, and the optional -S magnet enables CMSE / DMSE switches. Practical sizing: keep real work near 3534 N (about 0.6 of the 0.5 MPa rating), which is roughly 360 kg of vertical lift at a 2:1 margin.

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 ACED125X225 Is Used
Gantry Z-axis press fit
The 5890.5 N downward force presses bushings into housings on an automotive assembly cell, while the 225 mm stroke clears tall fixtures inside a guard sized for the short ISO 21287 body.
Reciprocating transfer beam
Rods on both ends let a pallet lift beam be driven from either side with equal 8246.7 N force at 0.7 MPa, and the through-rod keeps the beam square at 30-500 mm/s.
Heavy clamp on a welding fixture
Clamps steel plate weldments at up to 360 kg vertical equivalent, with the rear rod carrying a flag for a CMSE switch once the optional -S magnet is ordered.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X225 the Right Cylinder?
At 5890.5 N per direction this is the top of the ACED range; if your load needs under 3769.9 N at 0.5 MPa, the 100 mm bore ACED100 saves air and money, while there is no larger compact bore to step up to. Stroke 225 mm sits inside the 300 mm standard limit for bore 125, so no made-to-order build is needed. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must hold position. Order the -S code if you need CMSE / DMSE sensing, pick FA/FB flange, LB foot or FTC mounting, and specify G ports if PT is not your plant standard.
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 ACED125X225 FAQ
Yes - it is a double-rod cylinder, so force is equal extending and retracting: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction, peaking at 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, with a fixed TPU bumper at both ends.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. Sensing requires the optional -S magnet code - without it no magnet is fitted and no switch can be used; with -S, CMSE and DMSE switches sense position along the body slots.
