Airtac ACE Compact Cylinder ACE20X50
The AirTAC Airtac ACE Compact Cylinder ACE20X50 is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 50mm 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 ACE20X50
This AirTAC ACE20X50 is a double acting compact cylinder built to ISO 21287, with a 20 mm bore and 50 mm stroke. Its hard-anodized aluminium body and S45C hard-chrome plated rod deliver 157.1 N of push force at 0.5 MPa, making it a solid choice for light automation tasks.
Because the body is about 50% shorter than an ISO 15552 profile cylinder, it fits into tight machine guards and compact jigs where space is limited. For a real-world load, plan on lifting about 9.6 kg vertically at 0.5 MPa (157.1 N divided by 9.81, then halved for a safety margin), so you can match it against actual part weights with confidence.

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 ACE20X50 Is Used
PCB Soldering Fixture
Use the 50 mm stroke to lift a lightweight soldering iron guard or push a PCB carrier into position on a benchtop assembly station, where the compact body keeps the tool head low.
Blister Pack Ejector
In a small blister packaging line, this cylinder can eject a finished card from a die cavity with 157.1 N of push, clearing the next cycle without taking up extra machine length.
Small Parts Clamp
Mount it on a bench vise fixture to clamp plastic housings or cable connectors for drilling or gluing, relying on the fixed TPU bumper to soften the end of each stroke.
Is the Airtac ACE Compact Cylinder ACE20X50 the Right Cylinder?
When sizing, compare this 20 mm bore against a 16 mm bore which pushes 100.5 N, or step up to a 25 mm bore which pushes 245.4 N at 0.5 MPa. The 50 mm stroke falls well within the 100 mm maximum standard stroke for this bore, so it is a standard catalog item. Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted unless you order the optional -S version. The M5x0.8 port and female M6x1.0 rod thread suit light pneumatic circuits, and you can add FA/FB flange, LB foot, or CA/CB clevis mounts to fit standard ISO 21287 fixtures.
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 ACE20X50 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 is 32 kgf at 1.0 MPa, so you can size it for light pushing or lifting tasks with confidence.
No, this specific model has no magnet because it lacks the -S code. The optional -S magnet is required to mount CMSE or DMSE reed or solid-state switches. Without that magnet, the cylinder cannot trigger any sensor, so order the -S version if you need position feedback.
