Airtac ACED Double-acting Compact Cylinder ACED20X35S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X35S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 35mm stroke, M5×0.8 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 ACED20X35S
The ACED20X35S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 10 mm rod exits both covers, so the 20 mm bore delivers an equal 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa) because both strokes work on the rod-side area. The through-rod resists rotation and light side load, and the free back-end rod can carry a sensor flag or a second tool. This model carries the optional -S magnet, 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 a hard-chrome plated S45C rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, 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 jigs and guarding where a full-length body will not fit. For planning: about 70.7 N (roughly 7 kgf) is a realistic working force at 0.5 MPa, and with a 2:1 margin the rod lifts about 6 kg vertically.

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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACED20X35S Is Used
Small-part ejection from plastic moulds
The symmetric 117.8 N push and pull at 0.5 MPa ejects finished caps or connectors from shallow cavities, while the 35 mm stroke keeps the fixture footprint minimal.
Position-verified test stations
With the -S magnet fitted, CMSE or DMSE switches confirm both end positions of a 35 mm press-check stroke on electronics assembly benches.
Bidirectional push of PCB transfer carriages
Equal force both ways drives a light shuttle between two loading points on a conveyor line, and the rear rod carries a flag for mid-stroke sensing.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X35S the Right Cylinder?
At 117.8 N per side at 0.5 MPa this 20 mm bore suits light clamping and small-part transfer; step down to the 16 mm bore (75.4 N) for lighter work or up to the 25 mm bore (206.2 N) when more grip is needed. The 35 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, so it is a catalogue item. Like any plain double-rod cylinder it drifts when air is lost - add a rod lock or pilot check if the load must be held. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the -S magnet on this model enables CMSE / DMSE switch mounting.
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 ACED20X35S FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area of the 20 mm bore. Output is 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, identical in each direction, 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 M5x0.8 port serves both chambers.
The S in ACED20X35S means the optional -S magnet is fitted, so CMSE and DMSE reed or solid-state switches can be slid into the body slots to signal end positions. Without the -S code the cylinder ships with no magnet and no switching capability. The fixed TPU bumpers at both ends simply soften the stroke ends; they never hold or brake a load, so use a rod lock or pilot check where position must be kept with air off.
