Airtac ACED Double-acting Compact Cylinder ACED20X20SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X20SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED20X20SB
A double acting compact cylinder built to ISO 21287, the ACED20X20SB carries a piston rod through BOTH covers, so its 117.8 N output at 0.5 MPa (164.9 N at 0.7 MPa) is identical on the push and pull stroke. The 20 mm bore with 20 mm stroke suits tight clamping stations where a full-length body cannot fit, and the short frame saves about 50% of the mounting length of an ISO 15552 profile cylinder. The male rod thread (B code) bolts straight to tooling plates and knuckles.
The hard-anodized aluminium body with a hard-chrome plated S45C rod runs at 30-500 mm/s on air filtered to 40 um, across 0.15-1.0 MPa (22-145 psi). Because the through-rod exits both ends, it resists rotation and light side load, and the rear rod can carry a sensor flag. Fixed TPU bumpers absorb end-of-stroke shock at both covers. This model carries the optional -S magnet, so CMSE / DMSE switches can be fitted for position feedback. At 0.5 MPa the rod-side area lifts about 12 kg, so plan on roughly 6 kg for a 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 (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 ACED20X20SB Is Used
Small-parts press station
The equal 117.8 N force in both directions lets one ACED20X20SB press a connector into a PCB jig on the forward stroke and eject the finished part on the return, all within a 20 mm pitch.
Pick-and-place flag sensing
On a semiconductor tray handler, the rear rod carries a flag for a CMSE switch (enabled by the fitted -S magnet), confirming mid-stroke position without extra brackets.
Reciprocating slide drive
Driving a light inspection slide back and forth at 30-500 mm/s, the through-rod resists rotation so the camera mount stays square to the part on every cycle.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X20SB the Right Cylinder?
Size between the ACED16X20SB (75.4 N at 0.5 MPa) and the ACED25X20SB (206.2 N at 0.5 MPa); this 20 mm bore sits in the middle for light clamping and indexing. Both strokes deliver the same rod-side force, so no derating is needed on the return. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Choose FA/FB flange, LB foot or FTC mounting, and order CMSE / DMSE switches to pair with the fitted -S magnet.
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 ACED20X20SB FAQ
Yes - the double-rod design means both strokes use the rod-side area. At 0.5 MPa it produces 117.8 N, at 0.7 MPa it produces 164.9 N in EITHER direction, and the maximum force at 1.0 MPa is 24.0 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures and gantries. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body slots for end-of-stroke or mid-stroke detection. Fixed TPU bumpers at both ends absorb the piston's arrival, and FA/FB flange, LB foot or FTC brackets bolt to the standard ISO 21287 face.
