Airtac ACE Compact Cylinder ACE20X80B
The AirTAC Airtac ACE Compact Cylinder ACE20X80B is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 80mm 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 ACE20X80B
This AirTAC ACE20X80B is a double acting compact cylinder that delivers 157.1 N of push force at 0.5 MPa, making it a solid choice for light automation tasks. Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight guarding and compact jigs where space is at a premium.
With a male rod thread (B code) and M5x0.8 ports, this unit is ready for direct mounting. For a 2:1 safety margin on vertical lifts, plan for about 8 kg of real work at 0.5 MPa, not the full theoretical rating. This model has no magnet, so it cannot accept CMSE or DMSE sensors unless you order the optional -S version.

Where the Airtac ACE Compact Cylinder ACE20X80B Is Used
Small Part Stamping
Use the 157.1 N push at 0.5 MPa to actuate a small stamping die for marking metal tags or plastic nameplates in a bench-top press.
Light Conveyor Stop
Mount this cylinder to lift a light nylon stop pin on a small parts conveyor, diverting components into a chute at speeds up to 500 mm/s.
Jig Clamping
In a woodworking jig, this cylinder can clamp a workpiece with about 8 kg of effective force at 0.5 MPa, holding it steady for a dowel drilling operation.
Is the Airtac ACE Compact Cylinder ACE20X80B the Right Cylinder?
For lighter work, the ACE16 series offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25 gives you 245.4 N push for more demanding applications. This ACE20X80B is a middle-ground option that suits compact fixtures needing moderate force. Since it has no magnet, it is not suitable for position sensing without ordering the -S variant. The male rod thread simplifies attachment of custom tooling.
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 ACE20X80B 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.
No, this specific model has no magnet. To use CMSE or DMSE reed or solid-state switches, you must order the ACE20X80B-S version, which includes the optional -S magnet. The fixed TPU bumper at both ends handles end-of-stroke deceleration.
