Airtac ACED Double-acting Compact Cylinder ACED125X35B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X35B 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 ACED125X35B
A double acting ISO 21287 compact cylinder with a rod leaving both covers, the ACED125X35B delivers 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction, since both strokes work on the rod-side area. The male rod thread (B code) bolts straight to your tooling, and the 25 mm through-rod resists rotation and side load while the rear rod can carry a sensor flag. Its hard-anodized aluminium body runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with speeds of 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 125 mm bore fits heavy presses and clamping stations where a full-length profile cylinder will not. A fixed TPU bumper at each end absorbs end-of-stroke shock. Plan on roughly 3534 N (about 360 kgf) of usable work at 0.5 MPa, which corresponds to lifting about 300 kg vertically with a 2:1 margin. Note that when air is lost the piston drifts freely - add a rod lock or pilot check valve if the load must stay put. The optional -S magnet enables CMSE / DMSE switches; without that code no magnet is fitted.

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 ACED125X35B Is Used
Heavy press-fit station
The 5890.5 N through-rod force at 0.5 MPa presses bearings or bushings into housings on an automotive assembly line, with the male rod thread taking a custom press anvil.
Clamping fixture on a machining center
Symmetric force in both directions clamps and releases large castings in a 4-axis fixture, and the short body fits inside the fixture base where a profile cylinder cannot.
Counterweight lift on packaging machinery
The rear rod balances a forming tool or counterweight while the front rod does the work, lifting about 300 kg vertically with a 2:1 safety margin at 0.5 MPa.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X35B the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N at 0.5 MPa in both directions. If your load needs under 3769.9 N, the ACED100 bore saves space and air; if you need more than 8246.7 N at 0.7 MPa, step up to a larger frame cylinder. The 35 mm stroke sits well inside the 300 mm max standard stroke for this bore, so it ships as a standard part. Choose FA/FB flange, LB foot or FTC brackets plus I or Y rod knuckles to match the ISO 21287 mounting face, and add the -S code only if you need CMSE / DMSE position switches.
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 ACED125X35B FAQ
Because a rod exits both covers, force is equal in both directions: 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 pressure is 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
The ISO 21287 body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, and a fixed TPU bumper at each cover absorbs end-of-stroke energy without adjustment. FA/FB flange, LB foot and FTC brackets bolt to the standard face, the B code gives a male rod thread, and the optional -S magnet allows CMSE / DMSE switches.
