Airtac ACE Compact Cylinder ACE20X5H
The AirTAC Airtac ACE Compact Cylinder ACE20X5H is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 5mm 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 ACE20X5H
This AirTAC ACE20X5H is a double acting compact cylinder that extends and retracts its rod with air pressure, delivering a 157.1 N push force at 0.5 MPa. Its 5 mm stroke suits precise, short-travel motions in tight assembly fixtures where a full-length cylinder cannot fit.
Built to ISO 21287, the hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting space. The fixed TPU bumper absorbs end-of-stroke impact, and the M5x0.8 port simplifies air connection. For a safe working load, plan for about 94 N of real work at 0.5 MPa, which lifts roughly 9.6 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE20X5H Is Used
PCB Staking
Use the 5 mm stroke to press small standoffs onto circuit boards in a benchtop fixture, with the 157.1 N push ensuring consistent seating without damaging components.
Valve Stem Actuation
Drive a miniature pneumatic valve stem in a test rig, where the short stroke and 117.8 N retract force provide rapid, repeatable cycling at speeds up to 500 mm/s.
Label Applicator
Mount this cylinder in a labeling machine to advance a tamp pad 5 mm, applying labels with a firm 157.1 N push onto small product packages on a conveyor.
Is the Airtac ACE Compact Cylinder ACE20X5H the Right Cylinder?
For a lighter push, consider the ACE16X5 with 100.5 N at 0.5 MPa; for more force, step up to the ACE25X5 with 245.4 N. This model has no magnet, so order the -S code if you need CMSE or DMSE sensor feedback. Mounting options like FA or LB brackets bolt directly to the ISO 21287 face for easy integration.
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 ACE20X5H FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa, push is 219.9 N and pull is 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight spaces. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet enables CMSE or DMSE sensor mounting for position feedback.
