About the Airtac ACED Double-acting Compact Cylinder ACED25X50B
The ACED25X50B 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 output force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on each stroke, because both sides work on the rod-side area. The male rod thread (B code) lets you bolt accessories straight on, and the M5x0.8 ports suit small pneumatic manifolds. The hard-anodized aluminium body with a roller-burnished bore resists wear in high-cycle machines.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this 25 mm bore fits tight jigs, guarding and gantry frames. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the through-rod resists rotation and light side load while giving a symmetric mount. Plan on roughly 124 N of real work at 0.5 MPa (about 60% of the rating), which corresponds to lifting about 10 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s; operating pressure 0.15-1.0 MPa (22-145 psi).

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 ACED25X50B Is Used
Symmetric push-pull stamping jig
The equal 206.2 N force in both directions lets one ACED25X50B press a dowel in on the forward stroke and eject the finished part on the return, with the male thread carrying a custom press tip.
Bottling line gate diverter
A rod on each cover means the gate arm can be driven from either end of the cylinder body, and the 50 mm stroke is enough to swing a lane divider clear of 66 mm PET bottles.
Lab sample shuttle stage
The through-rod resists rotation so a vial tray stays square over 30-500 mm/s travel, and the short ISO 21287 body slides under a benchtop enclosure where a full-length cylinder will not fit.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X50B the Right Cylinder?
At 206.2 N per direction, the 25 mm bore sits between the 20 mm (117.8 N) and 32 mm (345.6 N) classes, so step up to 32 if your tooling mass grows or down to 20 for lighter pick-and-place heads. This unit has no magnet fitted; if you need CMSE or DMSE switch position feedback, order the -S variant instead. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard ISO 21287 face.
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 ACED25X50B FAQ
Yes - this is a double-rod cylinder, so a 10 mm rod exits both covers and every stroke uses the rod-side area. Force is 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in EITHER direction, with a maximum of 42.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and FTC brackets plus I/Y knuckles mount on the standard face. A fixed TPU bumper at each end absorbs end-of-stroke impact. Sensors are possible only on the -S version, which carries the optional magnet for CMSE / DMSE switches; this non-S model has no magnet, so no switch can be read on it.
