Airtac ACED Double-acting Compact Cylinder ACED125X20
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X20 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED125X20
A double acting compact cylinder built to ISO 21287, the ACED125X20 pushes a 125 mm bore through a short 20 mm stroke and delivers 5890.5 N in BOTH directions at 0.5 MPa, because a rod exits each cover and both strokes work on the rod-side area. The 25 mm through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tool. The hard-anodized aluminium body with an S45C hard-chrome plated rod keeps the package short enough to save about 50% of the mounting length of an ISO 15552 profile cylinder.
At 0.7 MPa the same bore reaches 8246.7 N either way, peaking at 1201.3 kgf at 1.0 MPa. For sizing, that means it lifts about 600 kg vertically at 0.5 MPa, and a practical plan is roughly 360 kg of real vertical work. Fixed TPU bumpers at both ends absorb end-of-stroke shock, speed runs 30-500 mm/s, and the 1/4" PT port feeds air filtered to 40 um over 0.15-1.0 MPa (22-145 psi). No magnet is fitted on this code; add the optional -S to enable 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 ACED125X20 Is Used
Heavy press-fit staking
Short-stroke staking of bearings or bushings into housings on an automotive assembly cell, where 5890.5 N at 0.5 MPa is enough and the compact body fits inside the press frame.
Pallet clamp-down
Clamping machined castings down onto fixture rails in a machining centre, using the through-rod to clamp from both sides of the fixture with equal force.
Mould slide actuation
Driving a short-travel mould slide or ejector plate on an injection tool, where the 20 mm stroke and symmetric rod mount keep the tool plate balanced.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X20 the Right Cylinder?
For a 20 mm stroke this is near the top of the range: a bore 100 ACED gives 3769.9 N at 0.5 MPa, while stepping up is not possible within the series, so if you need more than 5890.5 N both ways consider two cylinders or a larger actuator type. The 20 mm stroke suits short clamp-and-release or push-off motions where a long body would never fit. Note that a plain double-rod cylinder drifts when air is lost, so pair it with a rod lock or pilot check if the load must be held. Mount with FA/FB flange or LB foot brackets on the ISO 21287 face, and order the -S code if CMSE / DMSE position sensing is needed.
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 ACED125X20 FAQ
Yes, force is equal both ways because a rod exits each cover and both strokes use the rod-side area. At 0.5 MPa it delivers 5890.5 N, at 0.7 MPa it reaches 8246.7 N, and the maximum is 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and temperature -20 to +70 C.
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, so it fits tight jigs and guards. FA/FB flange and LB foot brackets bolt to the standard face, the fixed TPU bumpers at both ends absorb end-of-stroke energy, and the rod ends carry a female M16x2.0 thread with a 1/4" PT air port. The optional -S magnet enables CMSE / DMSE switches; without it no sensor can be mounted.
