Airtac ACED Double-acting Compact Cylinder ACED40X90S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X90S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 90mm stroke, 1/8" 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 ACED40X90S
A double acting compact cylinder built to ISO 21287, the ACED40X90S pushes a 40 mm bore through a 90 mm stroke with a piston rod leaving BOTH covers. Because each side of the piston sees the rod-side area, output force is identical in either direction: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a peak of 116.6 kgf at 1.0 MPa. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding and gantry frames. A hard-anodized aluminium body pairs with an S45C hard-chrome rod, and fixed TPU bumpers at both ends absorb end-of-stroke shock. The fitted -S magnet lets CMSE / DMSE switches report position, and the 90 mm stroke sits well inside the 200 mm standard range for this bore. As a working rule, plan on roughly 343 N of usable push at 0.5 MPa, which is about 29 kg lifted 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 (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 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 ACED40X90S Is Used
Fixture clamping on CNC pallets
Equal 571.8 N force in both directions clamps and releases a machined housing on a pallet changer, with CMSE switches confirming clamp state via the fitted magnet.
Bidirectional pusher on packaging lines
The through-rod pushes cartons off a conveyor from either cover at up to 500 mm/s, keeping the mount symmetric in a narrow frame saved by the compact body.
Lift-assist on electronics test rigs
About 29 kg of vertical lift with a 2:1 margin raises a probe head assembly over the 90 mm stroke, with DMSE switches marking top and bottom positions.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X90S the Right Cylinder?
Size between neighbours: the 32 mm bore gives 345.6 N at 0.5 MPa, while the 50 mm bore reaches 881.2 N, so the 40 mm class at 571.8 N covers mid-range clamping and transfer loads. Air supply is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and 1/8" ports. Note that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the load must stay put. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and the female M8x1.25 rod thread takes standard I or 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 ACED40X90S FAQ
Output is equal both ways because the double rod leaves the rod-side area active on each stroke: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of 116.6 kgf at 1.0 MPa. Ports are 1/8", the rod thread is female M8x1.25, and the 90 mm stroke is within the 200 mm standard limit for a 40 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, freeing space in guarded machines. This ACED40X90S carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped into the body slots for end-of-stroke or mid-stroke sensing. Fixed TPU bumpers at both ends soften the stroke ends.
