About the Airtac ACED Double-acting Compact Cylinder ACED125X70B
The ACED125X70B is a double acting, double-rod compact cylinder built to ISO 21287: a 25 mm hard-chrome-plated S45C rod exits both covers of the hard-anodized aluminium body, so thrust is identical on each stroke - 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. Because both sides see the rod-side area, there is no push-versus-pull mismatch to design around. The 70 mm stroke sits well inside the 300 mm standard range for this bore, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The through-rod resists rotation and side load and gives a symmetric fixture mount, while the rear rod can carry a cam or sensor flag. Fixed TPU bumpers at both ends absorb end-of-stroke shock. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s between -20 and +70 C. As a sizing guide, plan on roughly 3534 N of usable work at 0.5 MPa (about 60% of rating), which corresponds to lifting around 300 kg vertically with a 2:1 margin. The male rod thread (B code) suits clevis and knuckle fittings; the optional -S magnet enables CMSE / DMSE switches.

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 ACED125X70B Is Used
Baling and scrap compaction
The 5890.5 N symmetric thrust at 0.5 MPa drives a compaction platen in a recycling baler, with the through-rod guiding the platen straight under off-center scrap loads.
Pallet pusher on a loading line
A 70 mm stroke is enough to square pallets against a stop in a warehouse transfer station, and the rear rod carries a flag for a proximity switch when the -S magnet is ordered.
Glass sheet clamping gantry
In a float-glass handling frame, the equal-force double rod clamps from both faces of a fixture, and the compact body fits the tight gantry height where a full-length profile cylinder will not.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X70B 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 presses or up from the 80 mm bore (2356.2 N) if you need more margin. The 70 mm stroke is a standard length for this bore, so no made-to-order build is required. Remember that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the load must stay put. Choose FA/FB flange or LB foot mounting on the ISO 21287 face, and order the -S code if CMSE / DMSE position sensing is needed - without it there is no magnet in the piston.
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 ACED125X70B FAQ
Force 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 and 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 depends only on the 125 mm bore.
The ISO 21287 body is hard-anodized aluminium with threaded aluminium covers, a hard-chrome-plated S45C rod on both ends, and fixed TPU bumpers that absorb end-of-stroke energy. It saves about 50% of the mounting length of an ISO 15552 profile cylinder. Sensing requires the optional -S magnet code - order ACED125X70BS and CMSE / DMSE switches can be clipped to the body; the standard B version carries no magnet.
