About the Airtac ACED Double-acting Compact Cylinder ACED25X55B
The ACED25X55B is a double acting, double-rod compact cylinder built to ISO 21287: a 25 mm bore with a 55 mm stroke and a 10 mm piston rod leaving BOTH covers, so push and pull are identical at 206.2 N per side at 0.5 MPa (288.6 N at 0.7 MPa). The B code gives a male rod thread at each end. Its short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guarding and gantry frames where a full-length body simply will not fit.
The through-rod resists rotation and light side load and gives a symmetric mount, and the rear rod can carry a sensor flag in your fixture. With 206.2 N at 0.5 MPa, plan on roughly 124 N of real work (about 0.6 of the rating) or lift about 10 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, the S45C hard-chrome rod stands up to continuous cycling at 30-500 mm/s, and the optional -S magnet lets you add CMSE / DMSE switches when position feedback is needed.

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 ACED25X55B Is Used
Symmetric jig clamping
The equal 206.2 N push and pull lets one ACED25X55B both seat and retract a locating pin in a machining fixture without a return spring or unequal force.
Bidirectional part diverter
A packaging line pusher that must kick cartons off a conveyor in either stroke direction uses the identical rod-side force both ways at 0.5 MPa.
Reciprocating slide drive
Driving a small linear slide on an electronics assembly station, where the through-rod mount resists rotation at 30-500 mm/s cycle speeds.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X55B the Right Cylinder?
At 206.2 N per direction this 25 mm bore sits between the 20 mm size (117.8 N at 0.5 MPa) and the 32 mm size (345.6 N at 0.5 MPa), so step down for lighter pick-and-place loads or up when tooling weight climbs. The 55 mm stroke is well inside the 150 mm standard range for this bore, so no made-to-order build is required. Remember the piston will drift if air is lost - for a held vertical load add a rod lock or pilot check valve. Mount with FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles on the ISO 21287 face, and order the -S code only if CMSE / DMSE sensing is needed; this model has no magnet fitted.
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 ACED25X55B FAQ
Yes - the double-rod design means a 10 mm rod exits both covers, so both strokes use the rod-side area. Force is 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in EACH 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, and the air supply must be filtered to 40 um.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body about 50% shorter in mounting length than an ISO 15552 profile cylinder, an S45C hard-chrome rod on both ends, and a fixed TPU bumper at each stroke end. Sensing is not included: order the optional -S magnet code to enable CMSE or DMSE switches. Mounting options include FA/FB flange, LB foot and FTC brackets with I/Y rod knuckles; the port is M5x0.8 and the rod ends carry a male thread (B code).
