About the Airtac ACED Double-acting Compact Cylinder ACED25X5SB
The ACED25X5SB is a double acting, double-rod compact cylinder built to ISO 21287: a 25 mm bore with a very short 5 mm stroke, a 10 mm piston rod exiting BOTH covers, and a male rod thread (B code) on each end. Because both strokes work on the rod-side area, output force is equal in both directions - 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The hard-anodized aluminium body carries an S45C hard-chrome-plated rod, and a fixed TPU bumper sits at each end to absorb end-of-stroke energy.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 5 mm stroke unit slots into tight clamping nests and ejection positions where a full-length body will not fit. The through-rod resists rotation and light side load, and the rear rod end can carry a sensor flag. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke detection. A practical sizing rule: plan on roughly 124 N (about 12.6 kgf) of usable work at 0.5 MPa, and expect it to lift about 10 kg vertically with a 2:1 margin. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), -20 to +70 C, at 30-500 mm/s.

|---|---|
| 0.5 MPa | 206 N |

Where the Airtac ACED Double-acting Compact Cylinder ACED25X5SB Is Used
Print-head clamp step
The 5 mm stroke and equal 206.2 N force in both directions make the ACED25X5SB a compact clamp for holding a print head or sensor block during a short registration move.
Carton flag ejection
On a packaging line, the short body fits inside a guard where an ISO 15552 profile cylinder would be about twice as long, kicking a flag or tab with 206.2 N at 0.5 MPa.
Gauge flag on the rear rod
The back-end rod carries a flag past a CMSE or DMSE switch (enabled by the fitted -S magnet), giving a position signal from a 5 mm inspection stroke.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X5SB the Right Cylinder?
For a 5 mm nudge or clamp step, bore 25 gives 206.2 N both ways at 0.5 MPa - enough for small part ejection and locating pins. Step down to bore 20 (117.8 N at 0.5 MPa) for lighter nudges, or up to bore 32 (345.6 N at 0.5 MPa) when the part is heavier. Max standard stroke for this bore is 150 mm, so 5 mm is a standard build. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the position must hold. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and this -S version is ready for CMSE / DMSE switches.
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 ACED25X5SB FAQ
As a double-rod cylinder, force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on each stroke (both use the rod-side area). At 1.0 MPa the maximum output is 42.0 kgf. 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 it fits tight nests and guards. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for position detection. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles mount on the standard face, and each end has a fixed TPU bumper that absorbs end-of-stroke energy. It will not hold position if air is lost - use a rod lock or pilot check for that.
