About the Airtac ACED Double-acting Compact Cylinder ACED25X45SB
The ACED25X45SB is a double acting, double-rod compact cylinder built to ISO 21287: a 25 mm bore with a 45 mm stroke and a 10 mm rod leaving BOTH covers, so thrust is identical on the out-stroke and the return - 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction. The male rod thread (B code) suits external rod accessories, and air ports are M5x0.8. Because a rod exits each end, the through-rod resists rotation and light side load and the rear rod can carry a sensor flag.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight jigs and guarding. This unit carries the optional -S magnet, so CMSE / DMSE switches can be clamped straight onto the body slots for end-of-stroke signals. A fixed TPU bumper at each end absorbs stroke-end shock, and the hard-anodized aluminium body with an S45C hard-chrome rod stands up to daily cycling at 30-500 mm/s. As a rule of thumb, plan on about 124 N of real work at 0.5 MPa - roughly a 12 kg vertical pull with 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 ACED25X45SB Is Used
Symmetric parts ejector
The equal 206.2 N push and pull on a 45 mm stroke ejects machined bushings from a fixture and retracts the tool with identical force - no oversized bore needed.
Gated assembly station
With the -S magnet fitted, CMSE switches confirm both end positions of a 45 mm clamp stroke inside compact guarding where a full-length body will not fit.
Reciprocating test rig
The rear rod drives a counterweight or sensor flag while the front rod cycles a load at 30-500 mm/s, keeping the through-rod aligned stroke after stroke.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X45SB the Right Cylinder?
At 206.2 N (0.5 MPa) this 25 mm bore sits between the 20 mm size (117.8 N) and the 32 mm size (345.6 N) - step down for lighter pick-and-place, step up when the 32 mm rod-side force is needed. Remember the piston will drift if air is lost, so add a rod lock or pilot check valve for a held load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the -S magnet on this model enables CMSE / DMSE position sensing.
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 ACED25X45SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, on air filtered to 40 um.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. FA/FB flanges, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face, ports are M5x0.8, and this -S version carries the optional magnet so CMSE / DMSE switches mount in the body slots. A fixed TPU bumper at each end absorbs end-of-stroke shock.
