Airtac ACE Compact Cylinder ACE20X20S
The AirTAC Airtac ACE Compact Cylinder ACE20X20S is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 20mm 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 ACE20X20S
This AirTAC ACE20X20S is a double acting compact cylinder built to ISO 21287, with a 20 mm bore and a 20 mm stroke. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length unit will not. The S45C piston rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs impact.
At 0.5 MPa the push force is 157.1 N and the pull is 117.8 N. For a real application, plan on about 94 N of usable work at 0.5 MPa, which roughly lifts 9.6 kg vertically with a 2:1 safety margin. The optional -S magnet is fitted on this model, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing.

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 ACE20X20S Is Used
Compact Jig Clamping
Use the ACE20X20S to clamp small parts in a CNC fixture. The 157.1 N push at 0.5 MPa holds light workpieces, and the short body clears the spindle travel.
Small Part Ejection
Mount it on a conveyor line to push small components into a chute. The 20 mm stroke and 117.8 N pull retract quickly, keeping cycle times low.
Guard Door Actuation
Fit it to a machine guard door that needs a short, positive push to open. The fixed TPU bumper softens the stop, and the optional -S magnet signals the door position.
Is the Airtac ACE Compact Cylinder ACE20X20S the Right Cylinder?
For a smaller option, the ACE16X20 delivers 100.5 N push at 0.5 MPa, while the ACE25X20 steps up to 245.4 N. This ACE20X20S suits light automation tasks where space is tight and a 20 mm stroke is enough. The M5x0.8 port matches small bore fittings, and the female M6x1.0 rod thread accepts standard attachments. Since it is double acting, it extends and retracts with air, but it will not hold a load if pressure is lost - add a rod lock or pilot check valve if you need position holding. The fitted -S magnet enables CMSE or DMSE sensors for reliable end-of-stroke detection.
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 ACE20X20S FAQ
At 0.5 MPa, the push force is 157.1 N and the pull 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. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE20X20S has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits in confined areas like machine guards or small jigs. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE sensors to be mounted for position feedback.
