Airtac ACE Compact Cylinder ACE20X55
The AirTAC Airtac ACE Compact Cylinder ACE20X55 is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 55mm 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 ACE20X55
This AirTAC ACE20X55 is a double acting ISO 21287 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 at 0.5 MPa, which is enough for light assembly tasks but still fits in a body about 50% shorter than an ISO 15552 profile cylinder.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted. For a real-world rule of thumb, plan for about 94 N of usable work at 0.5 MPa, which equals lifting roughly 9.6 kg vertically with a 2:1 safety 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 | 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 ACE20X55 Is Used
Small Part Ejection
Use in a pick-and-place cell to eject small plastic components from a nest, where the 55 mm stroke clears the part and the 157.1 N force is ample for light parts.
Jig Clamping
Mount on a drill jig to clamp thin sheet metal during hole drilling. The compact body fits under the spindle, and the fixed TPU bumper prevents hard impacts on thin materials.
Label Applicator Press
Drive a label applicator head to press labels onto small boxes. The 55 mm stroke matches the label length, and the 117.8 N pull force retracts the head quickly.
Is the Airtac ACE Compact Cylinder ACE20X55 the Right Cylinder?
For a lighter duty, the ACE16X55 offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25X55 gives you 245.4 N push. This ACE20X55 sits in the middle, suitable for small clamps or light pushers. Remember that without the optional -S magnet, you cannot add position sensors, so order the -S version if you need feedback. The M5x0.8 port is standard for this bore size, and the female M6x1.0 rod thread accepts standard attachments.
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 ACE20X55 FAQ
At 0.5 MPa, push force is 157.1 N and pull force is 117.8 N. At 0.7 MPa, push rises to 219.9 N and pull to 164.9 N. The theoretical maximum force at 1.0 MPa is 32 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ACE20X55 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like under guards or inside gantries. It has a fixed TPU bumper at both ends to absorb end-of-stroke energy, but it does not lock or hold a load. For holding, use an external rod lock or pilot check valve.
