About the Airtac ACED Double-acting Compact Cylinder ACED25X50S
The ACED25X50S is a double acting, double-rod compact cylinder built to ISO 21287: a 25 mm bore with a 50 mm stroke and a 10 mm piston rod leaving both covers, so thrust is identical on the extend and retract strokes. At 0.5 MPa it delivers 206.2 N in either direction, rising to 288.6 N at 0.7 MPa. 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.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guarding and gantries. This -S version carries the optional magnet, so CMSE or DMSE reed and solid-state switches can be clipped to the body slots for end-of-stroke signalling. Fixed TPU bumpers at both ends absorb stroke-end energy, and the through-rod resists rotation while the rear rod can carry a sensor flag. In practice, plan on roughly 124 N of usable work force at 0.5 MPa, and the rod will lift about 10 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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 ACED25X50S Is Used
Pick-and-place on compact jigs
The symmetric through-rod gives a mirrored mount on either side of a 50 mm stroke, ideal for transferring small brackets between fixture nests where a full-length profile cylinder will not fit.
Position-checked press-fit station
With the fitted magnet driving CMSE or DMSE switches, a benchtop staking head gets confirmed extend and retract signals before the operator can load the next PCB support block.
Product rejector on a bottling line
Equal 206.2 N force both ways lets the back rod push a deflector while the front rod returns it, kicking underfilled bottles off a 30-500 mm/s conveyor without a direction-dependent speed change.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X50S the Right Cylinder?
At 206.2 N per direction at 0.5 MPa, the 25 mm bore sits between the 20 mm (117.8 N) and 32 mm (345.6 N) double-rod sizes; step up to 32 mm if your tooling needs more than about 200 N of working force. The 50 mm stroke is well inside the 150 mm standard range for this bore, so no made-to-order build is needed. Female M6x1.0 rod thread, PT ports, and FA/FB flange, LB foot, CA clevis or FTC brackets bolt straight to the ISO 21287 face. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put.
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 ACED25X50S FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area. At 0.5 MPa you get 206.2 N either way, 288.6 N at 0.7 MPa, and the maximum rating is 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
The ISO 21287 short body cuts mounting length by roughly half versus an ISO 15552 profile cylinder, so it fits shallow guarding and tight gantry bays. The S in ACED25X50S means the optional magnet is fitted on this unit, so CMSE or DMSE switches mount in the body slots for stroke-end detection; fixed TPU bumpers at each end absorb end-of-stroke energy.
