Airtac ACED Double-acting Compact Cylinder ACED25X35B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X35B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACED Double-acting Compact Cylinder ACED25X35B
A double acting, double-rod compact cylinder built to ISO 21287, the ACED25X35B pushes a 10 mm rod out of BOTH covers, so thrust is identical on every stroke: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The B code gives a male rod thread at each end, and the 25 mm bore runs on an M5x08 port - M5x0.8, that is - with air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. In practice, plan on roughly 124 N of usable work at 0.5 MPa - about 12 kg pulled or lifted with margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the hard-anodized aluminium body with S45C hard-chrome rod runs 30-500 mm/s from -20 to +70 C.

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 ACED25X35B Is Used
Symmetric push-pull fixture
A male-threaded rod on both ends lets a machining fixture clamp from either side with the same 206.2 N at 0.5 MPa, no direction-dependent tuning needed.
Packaging line reject pusher
The 35 mm stroke kicks off-spec cartons sideways at up to 500 mm/s, and the through-rod keeps the pusher plate square under light side load.
Sensor flag on the rear rod
Mount a flag on the back-end rod of a test-rig slide and read stroke position externally - order the -S code if you want CMSE/DMSE switching instead.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X35B the Right Cylinder?
At 206.2 N per direction, this 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) - step up if your tooling needs over 200 N. The 35 mm stroke is well inside the 150 mm standard range for bore 25, so it ships as a catalog item. Choose the B male rod thread when your fixture bolts onto the rod; FA/FB flange, LB foot and FTC brackets mount on the ISO 21287 face. If you need position feedback, order the -S variant instead - this code has no magnet, so CMSE or DMSE switches cannot be fitted. Note the piston will drift if air is lost; add a rod lock or pilot check for a held load.
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 ACED25X35B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the M5x0.8 port serves both chambers.
The compact body cuts mounting length by roughly half versus an ISO 15552 profile cylinder, so it fits shallow gantries and guarded cells. The B code supplies a male thread on both rod ends for direct fixture bolting, FA/FB flange, LB foot and FTC brackets attach to the standard face, and fixed TPU bumpers at each end soften the stroke. The magnet is the optional -S code; this unit has none, so no CMSE or DMSE switch can be mounted unless you order -S.
