Airtac ACED Double-acting Compact Cylinder ACED125X50S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X50S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 50mm 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 ACED125X50S
A double acting compact cylinder built to ISO 21287, the ACED125X50S pushes a 125 mm bore through a 50 mm stroke with a rod leaving both covers. Because each side sees the rod-side area, output is 5890.5 N at 0.5 MPa in either direction - no push/pull imbalance. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tooling plate.
The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at each end. This short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy presses and gantries where space is tight. At 0.5 MPa the rod can lift roughly 600 kg vertically, or about 300 kg with a 2:1 margin - enough to size a real load straight from the datasheet.

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 ACED125X50S Is Used
Heavy press and forming station
5890.5 N at 0.5 MPa both ways gives a 125 mm bore enough muscle for staking, crimping and light forming on aluminium brackets, with the 50 mm stroke matching short press-in operations.
Balanced lift-and-lower column
A rod on each cover lets the same through-rod raise and lower a die cart or fixture column with equal force, and the second rod end can drive a position flag for CMSE switches.
Clamping fixture on a machining line
The short ISO 21287 body fits inside machine guards where a full-length profile cylinder cannot, clamping cast housings at up to 8246.7 N at 0.7 MPa from either direction.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X50S the Right Cylinder?
At this force class the nearest smaller step is the ACED100X50S at 3769.9 N at 0.5 MPa; if you need more than 5890.5 N there is no larger ACED bore, so consider a bigger actuator type. The 50 mm stroke sits well inside the 300 mm maximum standard stroke for bore 125, so this is a catalogue item, not a made-to-order length. 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.
This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots for end-of-stroke signalling. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face. Rod end is female M16x2.0; ports are 1/4" PT (G on request).
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 ACED125X50S FAQ
It is a double-rod, double acting cylinder, so force is identical on both strokes: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal to about 600 kgf at the 1.0 MPa maximum. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, -20 to +70 C. For a real working figure, plan on roughly 3534 N (about 300 kg vertical lift with a 2:1 margin) at 0.5 MPa.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends to absorb end-of-stroke energy. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches mount in the body slots. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles attach directly to the standard face; the rod end is female M16x2.0 and ports are 1/4".
