Airtac ACE Compact Cylinder ACE20X70
The AirTAC Airtac ACE Compact Cylinder ACE20X70 is a genuine double acting 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 ACE Compact Cylinder ACE20X70
This AirTAC ACE20X70 is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod. With a 20 mm bore it delivers 157.1 N of push force and 117.8 N of pull force at 0.5 MPa, making it a solid choice for light automation tasks.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs. A practical rule is to plan for about 94 N of real work at 0.5 MPa, which means it can safely lift roughly 9.6 kg vertically with a 2:1 margin. The fixed TPU bumper absorbs energy at stroke ends, and the optional -S magnet code is required if you plan to use CMSE or DMSE sensors.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE20X70 Is Used
PCB Handling Pin
Use the 157.1 N push to actuate a locating pin that registers printed circuit boards before soldering. The short body fits under the conveyor deck where a longer cylinder would not.
Label Applicator Press
Drive a small tamp-blow label applicator head with the 70 mm stroke. The 117.8 N pull force retracts the head cleanly after each cycle at speeds up to 500 mm/s.
Jig Clamp for Drilling
Mount this cylinder to a drill jig to clamp thin aluminium parts during hole making. The 9.6 kg safe vertical lift capacity is ample for holding small workpieces firmly.
Is the Airtac ACE Compact Cylinder ACE20X70 the Right Cylinder?
For a lighter duty, the ACE16 offers 100.5 N push, while stepping up to the ACE25 gives you 245.4 N push at the same 0.5 MPa. This 70 mm stroke sits within the 100 mm maximum standard stroke for the 20 mm bore, so it ships as a standard item.
Since this model has no -S code, it has no magnet, meaning sensor mounting is not possible without ordering the optional -S version. The M5x0.8 port and female M6x1.0 rod thread are standard for this bore size.
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 ACE Compact Cylinder ACE20X70 FAQ
At 0.5 MPa the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa these increase to 219.9 N push and 164.9 N pull. The theoretical maximum force at 1.0 MPa is 32 kgf.
No, not on this exact model. This ACE20X70 does not have the optional -S magnet, so CMSE or DMSE switches cannot be fitted. You would need to order the ACE20X70S version to use those sensors.
