About the Airtac ACED Double-acting Compact Cylinder ACED20X40S
The ACED20X40S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format: a 20 mm bore with a 40 mm stroke and a 10 mm piston rod leaving BOTH covers, so output force is equal in both directions because each stroke works on the rod-side area. At 0.5 MPa it delivers 117.8 N either way, rising to 164.9 N at 0.7 MPa. The S in the code means the optional magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped onto the body for end-of-stroke signalling.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C, with a fixed TPU bumper at each end absorbing stop energy. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight fixtures and guarding. As a rule of thumb, plan on roughly 70 N (about 7 kg of vertical lift with a 2:1 margin) of usable work at 0.5 MPa rather than the full rating.

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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |

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 ACED20X40S Is Used
Compact jig clamping
The 117.8 N both-ways force and 40 mm stroke clamp small aluminium brackets inside a machining jig where the short ISO 21287 body fits a 50%-shorter envelope than a profile cylinder.
Position feedback on a pick unit
With the fitted -S magnet and CMSE switches on both covers, a small electronics pick-and-place slide confirms extend and retract on a 40 mm transfer stroke.
Symmetric push-pull testing
Equal 164.9 N at 0.7 MPa in each direction lets a lab fixture push and pull a connector sample with identical force, using the rear rod to drive a return indicator.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X40S the Right Cylinder?
Size this bore by load and space: if your job needs only about 75 N at 0.5 MPa, the 16 mm bore (75.4 N) is the lighter pick; if you need roughly 206 N, step up to the 25 mm bore (206.2 N). The 20 mm sits between them at 117.8 N both ways. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must be held. The through-rod resists rotation and light side load and can carry a sensor flag on the rear end; FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face. The fitted -S magnet accepts CMSE / DMSE switches; the female M6x1.0 rod thread suits standard rod accessories.
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 ACED20X40S FAQ
Because a rod exits both covers, both strokes use the rod-side area, so force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8. The 40 mm stroke is within the 100 mm maximum standard stroke for this bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow gantries and guarded stations. The S code means the optional magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches mount directly in the body slots for stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke impact, and FA/FB flange, LB foot or FTC mounting bolts to the standard ISO 21287 face.
