Airtac ACED Double-acting Compact Cylinder ACED80X40B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED80X40B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø80mm bore and 40mm stroke, 1/4" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED80X40B
A double acting, double-rod compact cylinder built to ISO 21287, the ACED80X40B pushes a 20 mm rod out of both covers, so the 80 mm bore delivers the same 2356.2 N at 0.5 MPa (3298.7 N at 0.7 MPa) on every stroke. The male rod thread from the B code bolts straight to your tooling, and the fixed TPU bumper at each end absorbs end-of-stroke shock. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s between -20 and +70 C.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight clamping stations and gantry frames a full-length body cannot fit. The hard-anodized aluminium body carries a roller-burnished bore, and the S45C hard-chrome plated rod resists wear. Because the through-rod exits both covers, it resists rotation and side load and gives a symmetric mount - the rear rod can even carry a sensor flag. For position sensing, order the optional -S magnet with CMSE / DMSE switches; this model without S has no magnet fitted. At 0.5 MPa, plan on roughly 1410 N (about 144 kg) of usable vertical work rather than the full 2356.2 N rating.

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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACED80X40B Is Used
Press-fit station for bearing bushings
The equal 2356.2 N force in both directions lets one ACED80X40B press a bushing home on the forward stroke and eject the finished part on the return, with the male rod thread picking up an interchangeable anvil.
Counterbalanced lift on a packaging gantry
A rod on each side of the 80 mm piston gives a symmetric pick-up point for a crosshead, and the through-rod resists the rotation a single-rod layout would introduce when lifting about 144 kg of tooling at 0.5 MPa.
Clamp-and-die changeover slide
The 40 mm stroke suits quick die-clamp slides on a stamping line, where the short ISO 21287 body fits inside the die shoe and the rear rod drives a proximity flag for position confirmation.
Is the Airtac ACED Double-acting Compact Cylinder ACED80X40B the Right Cylinder?
At 2356.2 N per direction at 0.5 MPa, the 80 mm bore sits between the 63 mm size (1458.1 N) and the 100 mm size (3769.9 N) - step down for lighter press-fit work, up for heavy forming. The 40 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Note that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check valve if the load must stay put. Mount with FA/FB flanges, LB feet or FTC brackets plus I/Y rod knuckles on the ISO 21287 face, and add the -S code if CMSE / DMSE switching is needed.
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 ACED80X40B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, with a maximum of 480.5 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 1/4" port matches the 80 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded cells. A fixed TPU bumper at each end absorbs end-of-stroke energy. Position sensing needs the optional -S magnet code - without S there is no magnet and no switch can be read; with -S, CMSE / DMSE switches mount in the body slots. Mounting brackets (FA/FB, LB, FTC) and I/Y knuckles bolt to the standard ISO 21287 face.
