Airtac ACE Compact Cylinder ACE20X90S
The AirTAC Airtac ACE Compact Cylinder ACE20X90S is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 90mm 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 ACE20X90S
This AirTAC ACE20X90S is a double acting compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. At 0.5 MPa it delivers 157.1 N of push force, which translates to a practical vertical lift of about 8 kg when you apply a 2:1 safety margin, making it a solid choice for light pick-and-place tasks.
Its ISO 21287 short body takes up roughly half the mounting length of an ISO 15552 profile cylinder, so it slides into tight machine frames and guarding where a longer unit will not fit. The S suffix means the optional magnet is fitted, so you can mount CMSE or DMSE reed or solid-state switches directly on the body for position sensing, and the fixed TPU bumper at each end absorbs the impact of fast cycling.

Where the Airtac ACE Compact Cylinder ACE20X90S Is Used
Jig Clamping on a CNC Mill
Use the 157.1 N push at 0.5 MPa to clamp small aluminum parts in a custom jig on a CNC mill, where the compact body fits under the spindle guard without obstructing the tool path.
Carton Tabbing Station
Drive a 90 mm stroke to fold and tab small cardboard cartons on a packaging line, with the optional magnet triggering a CMSE switch to confirm each tab is seated before the next box arrives.
Diverting Light Components
Position a small deflector arm on a conveyor to push lightweight plastic caps into a chute, relying on the 117.8 N pull force at 0.5 MPa to retract the arm quickly between cycles.
Is the Airtac ACE Compact Cylinder ACE20X90S the Right Cylinder?
For a lighter load, the ACE16X90S offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25X90S gives you 245.4 N push for heavier work in the same compact envelope. Since this is a double acting cylinder, it will not hold its position if air pressure is lost, so add a rod lock or pilot check valve if your application must hold a load when the system is off.
With the M5x0.8 port and a 90 mm stroke, this model suits short-travel automation. The fitted magnet lets you use CMSE or DMSE switches for end-of-stroke detection, and the FA or FB flange, LB foot, or CA clevis mounts bolt directly to the ISO 21287 face for quick 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 ACE20X90S 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 rises to 219.9 N and pull to 164.9 N. The theoretical maximum force at 1.0 MPa is 32 kgf. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE20X90S body is about 50% shorter than an ISO 15552 profile cylinder of the same stroke, so it fits into machine guards, gantries, and small fixtures where a standard-length cylinder would not. It has a hard-anodized aluminium body and a fixed TPU bumper at each end, which absorbs end-of-stroke impact but does not lock or hold a load.
