Airtac ACED Double-acting Compact Cylinder ACED125X75B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X75B 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 ACED125X75B
A double acting compact cylinder built to ISO 21287, the ACED125X75B pushes a 25 mm rod out of BOTH covers, so the 125 mm bore delivers the same 5890.5 N at 0.5 MPa (8246.7 N at 0.7 MPa) in either direction - both strokes work on the rod-side area. The male rod thread from the B code bolts straight to your tooling. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits press fixtures and gantries where a full-length body simply will not go.
In practice that force means real headroom: plan on roughly 3534 N (about 360 kgf) of usable work at 0.5 MPa, and with a 2:1 margin the rod lifts about 180 kg vertically. The hard-anodized aluminium body carries a fixed TPU bumper at each end to soften stroke ends, the S45C hard-chrome rod resists wear, and the through-rod on the back cover can carry a sensor flag or a second tool. Speed range is 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 ACED125X75B Is Used
Heavy stamping die clamp
The male-threaded 25 mm rod clamps a sheet-metal die shoe with 5890.5 N at 0.5 MPa, and the short ISO 21287 body tucks under the bolster where a profile cylinder would foul the bolster bolts.
Pallet elevator posts
Two ACED125X75B units lifting in parallel give about 720 kg of vertical capacity with a 2:1 margin, with equal force on rise and fall because a rod exits both covers.
Press-fit assembly station
Pressing bearings into housings needs symmetric force and a stiff guide - the through-rod resists rotation while the back-end rod carries a CMSE switch flag once the optional -S magnet is ordered.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X75B the Right Cylinder?
At 5890.5 N per direction this is the top of the ACED range - step down to the ACED100 (3769.9 N at 0.5 MPa) for lighter clamping, or stay here when forming, pressing or heavy lift-and-locate work demands it. The 75 mm stroke sits well inside the 300 mm maximum standard stroke for bore 125, so it ships as a catalog item. 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 flanges, LB feet and I/Y rod knuckles bolt to the ISO 21287 face, and the optional -S magnet code enables CMSE / DMSE switches - without -S there is no magnet 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 ACED125X75B FAQ
Yes - the double-rod design puts a 25 mm piston rod through both covers, so every stroke uses 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.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body - about 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy but does not hold or brake a load; use a rod lock or pilot check for that. FA/FB flanges, LB feet and I/Y knuckles mount on the standard face. Position sensing needs the optional -S magnet code with CMSE / DMSE switches; this model (no S) ships without a magnet.
