Airtac ACE Compact Cylinder ACE20X20
The AirTAC Airtac ACE Compact Cylinder ACE20X20 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 ACE20X20
This ACE20X20 is a double acting ISO 21287 compact cylinder that uses air to both extend and retract its 10 mm rod. Its 20 mm bore delivers 157.1 N of push force at 0.5 MPa, which is enough to handle light clamping and positioning tasks in automated assembly lines.
Built with a hard-anodized aluminium body, this unit is about 50% shorter than an ISO 15552 profile cylinder, freeing up valuable space in tight machine guards. The fixed TPU bumper at each end absorbs impact, and since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted unless you order the optional magnet version. For a safe working load, plan for about 94 N of real work at 0.5 MPa, which translates to lifting roughly 9.6 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE20X20 Is Used
PCB Alignment Pin
Use the ACE20X20 to push a locating pin into a PCB fixture during soldering. Its 157.1 N push at 0.5 MPa firmly seats the board, while the short body fits under the conveyor rail.
Label Applicator Press
Mount this cylinder in a blister-pack labeling station to press a label applicator head down. The 20 mm stroke cycles at up to 500 mm/s, keeping pace with a 60-part-per-minute line.
Small Parts Ejector
In a plastic injection mold, this cylinder ejects a small cap or plug from a cavity. The 117.8 N pull at 0.5 MPa retracts the ejector pin cleanly, and the compact body fits between mold plates.
Is the Airtac ACE Compact Cylinder ACE20X20 the Right Cylinder?
For a lighter duty, the ACE16X20 offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25X20 gives you 245.4 N push for heavier parts. This ACE20X20 sits in the middle, ideal for compact fixtures where space is tight but you still need a reliable 157.1 N of force.
Since this is a plain double acting cylinder, it will not hold its position if air pressure is lost; for a held load, add a rod lock or pilot check valve. The M5x0.8 port suits small-bore air lines, and you can order FA/FB flange, LB foot, or CA/CB clevis mounts to fit your jig.
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 ACE20X20 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 at 1.0 MPa is 32 kgf. These numbers are based on the official AirTAC datasheet for the 20 mm bore.
Yes, it is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight fixtures. This specific model has no magnet, so you cannot mount CMSE or DMSE sensors unless you order the -S version with the optional magnet. The fixed TPU bumper absorbs end-of-stroke impact but does not lock the rod.
