Airtac ACED Double-acting Compact Cylinder ACED40X20
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X20 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 20mm 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 ACED40X20
The ACED40X20 is a double acting compact cylinder built to ISO 21287, with a piston rod leaving BOTH covers so the 40 mm bore delivers an identical 571.8 N at 0.5 MPa (800.5 N at 0.7 MPa) on every stroke. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight jigs and guarding where a full-length body cannot fit.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag on packaging or assembly machinery. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated rod stands up to continuous cycling. In practice, plan on roughly 343 N of usable work at 0.5 MPa, which lifts about 29 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

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 ACED40X20 Is Used
Press-fit ejector
The symmetric 571.8 N push and pull on a 20 mm stroke ejects finished bushings from a press die, with the rear rod driving a scrap flag.
Bottle-line gate
A 1/8" port and 30-500 mm/s speed let the through-rod swing a reject gate on a beverage conveyor, recovering fast in both directions.
Fixture clamp
About 29 kg of vertical lift capacity with margin clamps aluminium housings in a CNC fixture, the short body fitting under the spindle guard.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X20 the Right Cylinder?
At 571.8 N per side, the 40 mm bore sits between the 32 mm (345.6 N) and 50 mm (881.2 N) options, so step down for lighter clamping or up when the load grows. The 20 mm stroke is well inside the 200 mm maximum standard stroke for this bore. Remember the piston drifts if air is lost - for a held load add a rod lock or pilot check valve. Mount with FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles, and order the -S code if you need the optional magnet for CMSE / DMSE switches; without -S there is no magnet fitted.
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 ACED40X20 FAQ
Because a rod exits both covers, both strokes use the rod-side area: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, equal in push and pull. At 1.0 MPa the peak is 116.6 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, running at 30-500 mm/s on air filtered to 40 um.
It is an ISO 21287 compact cylinder whose body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end to absorb end-of-stroke energy. It mounts via FA/FB flange, LB foot or FTC brackets, and the optional -S magnet enables CMSE / DMSE switches - without -S no magnet is installed.
