Airtac ACED Double-acting Compact Cylinder ACED20X70
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X70 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 70mm 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 ACED20X70
The ACED20X70 is a double acting, double-rod compact cylinder built to ISO 21287: a 10 mm hard-chrome-plated S45C rod exits both covers, so the 20 mm bore delivers an identical 117.8 N at 0.5 MPa (164.9 N at 0.7 MPa) on every stroke. The hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight pick-and-place heads and small guarding frames. A fixed TPU bumper at each end absorbs end-of-stroke shock.
Because the through-rod resists rotation and carries side load symmetrically, the back-end rod is a handy mount for a sensor flag or a second tool. Plan on roughly 70 N (about 7 kg) of usable vertical work at 0.5 MPa instead of the full 117.8 N rating. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the female M6x1.0 rod thread takes standard knuckles. The magnet is optional: order the -S code to enable CMSE / DMSE switches.

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 ACED20X70 Is Used
Small-part ejection from plastic molds
The symmetric 117.8 N push and pull at 0.5 MPa knocks finished 20-50 g parts off the core and retracts with equal force, while the 70 mm stroke clears shallow mold pockets.
Pusher on a bottle-sorting conveyor
A through-rod pusher deflects PET bottles between lanes at 30-500 mm/s; the back-end rod carries a flag for a CMSE switch when the -S magnet is ordered.
Sample lift in a lab autosampler
With a usable vertical margin of about 7 kg at 0.5 MPa, the double rod raises and lowers sample trays without rotating, guided by the symmetric through-rod mount.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X70 the Right Cylinder?
At 117.8 N per direction, this bore suits light clamping, sorting and small-part transfer; step down to a 16 mm bore (75.4 N at 0.5 MPa) for lighter fixtures or up to a 25 mm bore (206.2 N at 0.5 MPa) when the load grows. The 70 mm stroke sits inside the 100 mm maximum standard stroke for bore 20, so it ships as a catalogue item. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a load must stay put. Choose FA/FB flange or LB foot brackets on the ISO 21287 face, and add the -S code only if you need CMSE / DMSE position switches.
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 ACED20X70 FAQ
Yes - the double-rod design means 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) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Sensing is optional: order the -S version to get the magnet that works with CMSE / DMSE switches; the standard ACED20X70 has no magnet fitted.
