Airtac ACED Double-acting Compact Cylinder ACED125X45S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X45S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 45mm 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 ACED125X45S
The ACED125X45S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 25 mm rod exits both covers, so the 125 mm bore delivers an identical 5890.5 N at 0.5 MPa (8246.7 N at 0.7 MPa) in each direction - both strokes work on the rod-side area, with no push-versus-pull difference to design around. The through-rod resists rotation and side load and gives a symmetric mounting face, and the rear rod can carry a sensor flag on gantry axes.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s and -20 to +70 C, with a fixed TPU bumper at each end absorbing end-of-stroke energy. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 125 mm bore fits heavy presses and clamping fixtures where a full-length body would not. At 0.5 MPa, plan on roughly 3534 N of usable work force, which corresponds to lifting about 300 kg vertically with a 2:1 margin. The S in the model code means the magnet is fitted, so CMSE / DMSE switches can be mounted anywhere along the body slots.

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 ACED125X45S Is Used
Heavy press-fit stamping station
The equal 5890.5 N output in both directions suits a press-fit head that must push a bearing home and retract the part with the same force, inside a guard sized for the short ISO 21287 body.
Pallet lift-and-lower column
With about 300 kg of vertical lift capacity at a 2:1 margin, a pair of these cylinders can raise and lower automotive pallet fixtures on a 45 mm shuttle stroke, with the rear rod carrying a position flag.
Steel coil clamping fixture
The through-rod resists the side load of a coil-edge clamp, and the fitted magnet with DMSE switches confirms full clamp before the mill table indexes.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X45S the Right Cylinder?
At 5890.5 N per side at 0.5 MPa, the 125 mm bore is the top of the ACED range; step down to the 100 mm bore (3769.9 N) for lighter clamp loads or stay here for press-fit and heavy-lift duty. The 45 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so it is a catalogue item with no made-to-order lead time. Mount with FA/FB flanges, LB foot or FTC brackets plus I/Y rod knuckles on the ISO 21287 face, and remember that a plain double-rod cylinder will drift if air is lost - add a rod lock or pilot check for held loads. The fitted magnet pairs directly with CMSE / DMSE switches for end-of-stroke or mid-stroke signalling.
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 ACED125X45S FAQ
Yes - the double-rod design puts a 25 mm rod through both covers, so every stroke uses the rod-side area of the 125 mm bore. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal in both directions, 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, and the 45 mm stroke is within the 300 mm standard maximum for this bore.
The ACED125X45S uses the ISO 21287 short-body format - 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 each end that decelerates the piston at end of stroke. The S in the code means the magnet is fitted on this unit, so CMSE reed or DMSE solid-state switches clip into the body slots for position feedback; without the -S code the cylinder ships with no magnet. Air supply should be filtered to 40 um.
