Airtac ACED Double-acting Compact Cylinder ACED25X35SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X35SB 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 ACED25X35SB
The ACED25X35SB is a double acting, double-rod ISO 21287 compact cylinder: a piston rod leaves both covers, so the 25 mm bore delivers an equal 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in each direction - both strokes work on the rod-side area. The male rod thread (B code) bolts straight into knuckles and tooling, and the fitted -S magnet lets CMSE / DMSE switches report position along the body slots.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. A hard-anodized aluminium barrel carries the S45C hard-chrome 10 mm rod, with a fixed TPU bumper at each end to soften end-of-stroke contact. As a rule of thumb, plan on roughly 123 N of usable work at 0.5 MPa - about 12 kg held vertically with a 2:1 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 ACED25X35SB Is Used
Symmetric clamping of machined housings
The through-rod clamps an aluminium gearbox housing from both sides of a CNC fixture with one cylinder, delivering 206.2 N on each face at 0.5 MPa and keeping the fixture footprint short.
Two-sided part ejection on packaging lines
Mounted beside a conveyor, the back rod pushes rejected cartons while the front rod resets a guide - equal 288.6 N at 0.7 MPa on both strokes keeps timing consistent at up to 500 mm/s.
Position-flagged lift station in an assembly cell
The rear rod carries a sensor flag while the front rod lifts connector trays of about 12 kg; the fitted -S magnet drives CMSE switches for end-of-stroke confirmation in the PLC.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X35SB the Right Cylinder?
At 206.2 N per direction, this 25 mm double-rod unit sits between the 20 mm bore (117.8 N) and the 32 mm bore (345.6 N) - step down for lighter pick-and-place, up if your jig needs nearly 350 N. The 35 mm stroke is well inside the 150 mm standard range for bore 25, so it ships as a catalog item. Remember the through-rod does not hold position on lost air; add a rod lock or pilot check valve for a suspended load. FA/FB flanges, LB feet and CA clevis mounts bolt to the ISO 21287 face, and the male rod thread suits I/Y knuckles.
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 ACED25X35SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal either way: 206.2 N at 0.5 MPa and 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 port is M5x0.8.
The ISO 21287 short body takes about 50% less mounting length than an ISO 15552 profile cylinder, which matters inside tight gantries and guards. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots for stroke-end signals. A fixed TPU bumper at each end absorbs end-of-stroke impact, and FA/FB flange, LB foot or CA clevis mounts bolt straight onto the standard face.
