Airtac ACE Compact Cylinder ACE80X20S
The AirTAC Airtac ACE Compact Cylinder ACE80X20S is a genuine double acting ISO 21287 compact air cylinder with a Ø80mm bore and 20mm stroke, 1/4" 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 ACE80X20S
This AirTAC ACE80X20S is a double acting compact cylinder that delivers 2513.3 N of push force at 0.5 MPa, making it a strong choice for heavy clamping or pressing tasks. Its 20 mm stroke suits short-travel operations where space is tight, and the hard-anodized aluminium body keeps it durable yet lightweight.
Because the body is ISO 21287 compact, it takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it fits into confined jigs and guarding. The built-in optional -S magnet allows CMSE or DMSE switches to sense the piston position, and the fixed TPU bumper at both ends absorbs end-of-stroke impacts for smoother cycling. For a safe working load, plan for about 1508 N of real work at 0.5 MPa, which translates to lifting roughly 154 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE80X20S Is Used
Clamping fixture
Use the 2513.3 N push force to clamp sheet metal parts securely in a welding jig, with the short stroke keeping the fixture compact.
Carton press
In a packaging line, this cylinder can press down on carton flaps before sealing, providing consistent force in a limited vertical space.
Machine guard interlock
Mount it to slide a safety guard into place on a press brake, using the -S magnet to confirm the guard position with a sensor.
Is the Airtac ACE Compact Cylinder ACE80X20S the Right Cylinder?
When sizing, compare this 80 mm bore to a 63 mm bore (1558.6 N push at 0.5 MPa) if you need less force, or step up to a 100 mm bore (3927.0 N push at 0.5 MPa) for heavier loads. The 20 mm stroke is short, so confirm your travel needs; the max standard stroke for this bore is 300 mm, and longer strokes are made to order. This model comes with the -S magnet, so you can mount CMSE or DMSE sensors for position feedback, and the 1/4" port is ready for standard fittings. Since this is a plain double acting cylinder, it will not hold its position if air pressure is lost; use a rod lock or pilot check valve for load holding.
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 ACE80X20S FAQ
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2356.2 N. At 0.7 MPa, push is 3518.6 N and pull is 3298.7 N. The theoretical maximum force is 512.6 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi).
The magnet is an optional feature, but this specific model (ACE80X20S) includes it because of the -S code. With the magnet, you can mount CMSE or DMSE reed or solid-state switches for position sensing. Without the -S code, the cylinder has no magnet and sensors cannot be used.
