Airtac ACED Double-acting Compact Cylinder ACED125X225SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X225SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 225mm 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 ACED125X225SB
A double acting ISO 21287 compact cylinder with a rod leaving both covers, the ACED125X225SB pushes with identical force on every stroke because both sides work on the rod-side area: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal in each direction. The 25 mm through-rod resists rotation and side load, and the rear rod end is free for a sensor flag or a symmetric fixture mount.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C, with a fixed TPU bumper at each end. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 225 mm stroke fits gantries and press frames that cannot spare the length. At 0.5 MPa the rod-side force equals roughly 600 kg of pull, so plan on about 360 kg of real work, or lift about 300 kg vertically with a 2:1 margin.

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 ACED125X225SB Is Used
Heavy stamping die transfer
The through-rod carries a die cart locator from both sides with 5890.5 N in either direction, and the 225 mm stroke clears the die shuttle inside a tight press cell.
Pallet elevator lift shaft
With about 600 kg of rod-side force at 0.5 MPa, the twin 25 mm rods lift a loaded pallet vertically with margin, the second rod keeping the tooling plate square.
Weld fixture clamping bridge
A car-body weld gantry uses the equal bidirectional force to press and retract a clamping bridge, with CMSE switches on the fitted magnet confirming both end positions.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X225SB the Right Cylinder?
At 5890.5 N per direction this 125 mm bore sits at the top of the ACED range; step down to the 100 mm bore (3769.9 N at 0.5 MPa) for lighter clamping, or stay here when a 63 mm bore (1458.1 N) is far too small. Stroke 225 mm is within the 300 mm standard limit for this bore, so no made-to-order build is needed. 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. The male rod thread (B code) suits clevis-style knuckles, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke signals.
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 ACED125X225SB 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 on every stroke, peaking at 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the 225 mm stroke fits shallow machine frames. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots for position feedback. A fixed TPU bumper at each end absorbs end-of-stroke impact, and FA/FB flange or LB foot brackets bolt to the standard face.
