Airtac ACED Double-acting Compact Cylinder ACED125X75
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X75 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 75mm 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 ACED125X75
A double acting compact cylinder built to ISO 21287, the ACED125X75 pushes a 125 mm bore through a 75 mm stroke with a rod leaving both covers. Because each side works on the rod-side area, output is identical in both directions: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, the strongest force class in the ACED range. The hard-anodized aluminium body is roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, so this heavy-duty thrust fits presses and fixtures where a full-length body cannot.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag or a second tooling plate. A fixed TPU bumper at each end absorbs end-of-stroke energy. For planning, treat about 3534 N (roughly 360 kg of push) as the working figure at 0.5 MPa, or expect it to lift about 300 kg vertically with a 2:1 margin. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the rod ends in a female M16x2.0 thread.

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 ACED125X75 Is Used
Heavy stamping and forming fixtures
The 5890.5 N bidirectional thrust at 0.5 MPa clinches, stamps and forms steel brackets in a 75 mm working window inside a compact press frame.
Pallet lift-and-lower stations
A through-rod on both ends lets one cylinder raise and lower a 300 kg pallet plate with a 2:1 vertical margin, guided by the rotation-resistant rod.
Clamping gantries on machining lines
The short ISO 21287 body slots between gantry rails to clamp turbine housings, with the rear rod driving a second clamp or a sensor flag.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X75 the Right Cylinder?
At 5890.5 N per direction this is the top of the ACED line; if your job needs less than about 3770 N at 0.5 MPa, the ACED100 saves cost and space, while there is no larger bore in the series. Remember the piston drifts if air is lost, so add a rod lock or pilot check valve for a held load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. This code has no magnet; order the -S variant if you need CMSE / DMSE switch detection.
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 ACED125X75 FAQ
Output is equal both ways because a rod exits each cover and both strokes use the rod-side area: 5890.5 N at 0.5 MPa, 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, and the 1/4" port matches the 125 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB, LB or FTC mounting on the standard face. Sensing is not included on this code: order the optional -S magnet to enable CMSE / DMSE switches along the body slots.
