Airtac ACED Double-acting Compact Cylinder ACED40X20S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X20S 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 ACED40X20S
A double acting compact cylinder built to ISO 21287, the ACED40X20S has a piston rod leaving both covers, so the 40 mm bore delivers the same 571.8 N at 0.5 MPa (800.5 N at 0.7 MPa) on every stroke - no push-pull imbalance to design around. The through-rod resists rotation and light side load, and its rear end is a ready mounting point for a sensor flag. The magnet is fitted on this -S version, so CMSE or DMSE reed and solid-state switches can be clipped straight onto the body slots.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s and -20 to +70 C, with a fixed TPU bumper at each end. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight fixtures - and at 0.5 MPa you can plan on roughly 343 N of real work, or about 29 kg of 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 (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 ACED40X20S Is Used
Symmetric clamp fixtures
The equal 571.8 N force in both directions lets one ACED40X20S clamp and release a machined housing in a CNC fixture with identical grip either way.
Position-flagged indexing
With the -S magnet fitted, CMSE or DMSE switches on the body slots confirm end positions of a 20 mm index slide on an assembly dial table.
Compact press station
About 29 kg of vertical lift capacity at a 2:1 margin suits short-stamp or marking heads on electronics lines where body length is restricted.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X20S the Right Cylinder?
At 571.8 N per direction, the 40 mm bore sits between the 32 mm (345.6 N at 0.5 MPa) and the 50 mm (881.2 N at 0.5 MPa) - step down for lighter clamping, up for heavier pressing. Remember the piston drifts if air is lost, so add a rod lock or pilot check where a load must stay put. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted magnet means CMSE / DMSE switching works out of the box.
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 ACED40X20S FAQ
Because a rod exits both covers, force is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa on every stroke, with a peak of 116.6 kgf at 1.0 MPa. The rod is 12 mm with a female M8x1.25 thread, the port is 1/8" (PT), and the standard stroke range for this bore runs to 200 mm, so 20 mm is a standard build.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot or FTC brackets attach directly to its face. This -S version carries the optional magnet, so CMSE / DMSE switches mount in the body slots; a fixed TPU bumper at each end absorbs end-of-stroke energy.
