About the Airtac ACED Double-acting Compact Cylinder ACED32X40S
The ACED32X40S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format, with a 32 mm bore and 40 mm stroke. A piston rod exits both covers, so the through-rod gives equal output force in each direction and resists rotation and side load. At 0.5 MPa it delivers 345.6 N either way, and 483.8 N at 0.7 MPa. Because both strokes use the rod-side area, you never need to derate for the pull direction.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. The S in the code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the body slots. As a rule of thumb, plan on about 207 N of usable work at 0.5 MPa, which is roughly a 17 kg vertical lift 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 (Ø32mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 ACED32X40S Is Used
Pick-and-place on a PCB handling gantry
The through-rod carries a gripper on the front and a counter-mount on the rear, giving symmetric 345.6 N clamping either way at 0.5 MPa, while the 40 mm stroke covers tray-to-chute transfer in a tight gantry frame.
End-of-stroke verification on an assembly fixture
With the -S magnet fitted, CMSE or DMSE switches confirm the piston has fully seated in a 40 mm press-fit station, feeding a PLC interlock before the next fastening cycle starts.
Synchronous clamp on a packaging carton sealer
A rod on each cover lets one cylinder push two opposing pads with equal 345.6 N force at 0.5 MPa, squaring cartons on a sealer line at speeds up to 500 mm/s without side-load twist.
Is the Airtac ACED Double-acting Compact Cylinder ACED32X40S the Right Cylinder?
Size around the load: the next bore down, ACED25, gives 206.2 N at 0.5 MPa, while ACED40 steps up to 571.8 N. If your part weighs near 17 kg and you want a 2:1 vertical margin, the 32 mm bore at 345.6 N is the right class. Stroke 40 mm sits well inside the 200 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build.
This model carries the optional -S magnet, so position feedback via CMSE / DMSE switches is ready to wire. Mounting brackets (FA/FB flange, LB foot, FTC) plus I and Y rod knuckles bolt to the ISO 21287 face. Note that a plain double-rod cylinder drifts when air is lost; for a held load, add a rod lock or pilot check valve. Female M8x1.25 rod thread, PT ports.
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 ACED32X40S FAQ
Yes. Because a rod exits both covers, both strokes work on the rod-side area, so force is equal either way: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa. The maximum rating at 1.0 MPa is 70.5 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, speed 30-500 mm/s, and temperature -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits shallow guards and fixtures. The S means the optional -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches mount in the body slots for position feedback. A fixed TPU bumper at each end absorbs end-of-stroke shock, and FA/FB flange, LB foot or FTC brackets bolt straight to the standard face.
