Airtac SAUD Double Rod Cylinder SAUD100X280S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X280S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 280mm stroke, 1/2" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUD Double Rod Cylinder SAUD100X280S
The AirTAC SAUD100X280S is a double-acting, double-rod profile cylinder. A 25 mm rod exits both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side piston area. This gives equal output force in both directions, rated at 3681 N each way at 0.5 MPa. The extruded profile is shorter than an ISO 15552 cylinder of the same 100 mm bore.
Because of the twin rods, the unit resists torsional twist for non-rotating guidance and can carry a sensor cam on the back rod. This -S SKU includes a piston magnet for CMSG, DMSG or EMSG switches. Operating pressure is 0.15-1.0 MPa with a 1/2 inch port.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD100X280S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, keeping force perfectly balanced across both tools during metal cutting.
Dual Transfer Pushers
Pushes pallets from either side of a line using both rod ends, maintaining parallel contact without torsional deflection.
Vertical Lift Fixture
Hoists heavy 188 kg fixtures vertically with equal pull and push force, using the back rod to trigger a DMSG descent sensor.
Is the Airtac SAUD Double Rod Cylinder SAUD100X280S the Right Cylinder?
When sizing this 100 mm bore, note the equal both-ways force is 3681 N at 0.5 MPa. Stepping down, the 80 mm bore yields 2268 N each way. Stepping up is not possible as 100 mm is the largest in the series. Choose this double-rod model when you need anti-rotation stability, twin tooling on one piston, or rear-end switch tripping. It shares FA flange and LB foot mounting with the AirTAC SC series. For this 280 mm stroke, ensure external guide rails carry any heavy lateral load to prevent rod binding. The -S magnet allows solid-state position sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUD Double Rod Cylinder SAUD100X280S FAQ
The force is equal in both directions because both faces have a 25 mm rod. It produces 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port supplies air to achieve these figures.
No, a plain double-rod cylinder drifts without live air. The 29 mm adjustable cushions only decelerate the piston near stroke end. For dead-load holding, fit an external rod lock or pilot-operated check valve.
