Airtac ACED Double-acting Compact Cylinder ACED25X45B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X45B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED25X45B
The ACED25X45B is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 10 mm hard-chrome-plated S45C rod exits BOTH covers, so the 25 mm bore delivers the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) in each direction - there is no push/pull imbalance because both strokes work on the rod-side area. The male rod thread (B code) bolts straight to your tooling, and the through-rod resists rotation and light side load while the free back-end rod can carry a sensor flag or a second fixture.
The hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. Fixed TPU bumpers at both ends absorb end-of-stroke shock, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). In practice, plan on roughly 124 N of usable work at 0.5 MPa - about 12 kg - or lift around 6 kg vertically with a 2:1 margin. Note this unit has no magnet fitted; order the -S code if you need CMSE / DMSE switch sensing.

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 ACED25X45B Is Used
Symmetric jig clamping
The equal 206.2 N force in both directions lets one ACED25X45B clamp a machined aluminium bracket from either side of a drilling fixture with identical pressure.
Reciprocating test slide
A through-rod drives a leak-test slide back and forth at 30-500 mm/s on a lab bench, with the rear rod carrying a flag for position verification.
Carton pusher on a tight frame
The short ISO 21287 body fits inside a compact case-packing gantry where a full-length profile cylinder cannot, pushing cartons at 45 mm travel.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X45B the Right Cylinder?
At 206.2 N per direction, the 25 mm bore suits clamping and positioning loads up to roughly 12 kg of practical work at 0.5 MPa. Step down to the 20 mm bore (117.8 N at 0.5 MPa) for lighter pick-and-place, or up to the 32 mm bore (345.6 N at 0.5 MPa) when the load grows. Stroke 45 mm sits well inside the 150 mm standard range for this bore. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a load must be held. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles mount on the standard ISO 21287 face, and the male rod thread (B) takes your tooling directly.
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 ACED25X45B 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 and 288.6 N at 0.7 MPa. At 1.0 MPa the bore reaches a maximum of 42.0 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C and 30-500 mm/s speed.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends to absorb end-of-stroke shock. Sensing is not fitted on this model: the magnet is the optional -S code. Order ACED25X45BS to enable CMSE or DMSE switches; without -S no magnet is inside and no sensor can be read.
