Airtac SAUD Double Rod Cylinder SAUD100X85
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X85 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 85mm 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 SAUD100X85
The AirTAC SAUD100X85 is a double-acting double-rod profile cylinder with an 85 mm stroke. A 25 mm rod exits both ends of the hard-anodized aluminum extrusion, yielding identical push and pull thrust of 3681 N each way at 0.5 MPa. This compact body is shorter than a standard 100 mm bore ISO 15552 unit.
Because both faces share the same rod-side area, output is perfectly balanced. The design suits synchronized twin-tool driving and anti-twist guidance. This base SKU lacks a magnet, so it cannot host CMSG or DMSG switches. The 1/2 inch port feeds the 100 mm bore, and a Viton H seal can extend operation to 150 C.

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 SAUD100X85 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, ensuring perfectly balanced feed rates without torsional deflection.
Balanced Vertical Lift
Raises and lowers a 188 kg platen with equal force, preventing gravity-induced drift during the downward travel phase.
Dual Transfer Pushers
Pushes parts from both ends simultaneously on a conveyor line, keeping the transfer stroke perfectly aligned without twisting.
Is the Airtac SAUD Double Rod Cylinder SAUD100X85 the Right Cylinder?
Choose this 100 mm bore if your application demands high bidirectional thrust and anti-rotation stability. Stepping down, the 80 mm bore provides 2268 N each way at 0.5 MPa. Stepping up is impossible as 100 mm is the largest available SAUD size. Select a double-rod profile when you need to drive two tools at once or mount a cam on the back rod. Mounting is limited to Basic, FA, and LB brackets that match the AirTAC SC series. For this 85 mm stroke, side loading is minimal, but any future upgrade beyond 300 mm requires external guide rails to prevent binding. Add the -S suffix if you require magnetic 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 SAUD100X85 FAQ
The output force is equal in both directions because a 25 mm rod exits both ends. It generates 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 the 100 mm bore to achieve these figures.
No, a plain double-rod cylinder drifts without live air, as the 29 mm cushions only decelerate near stroke end. For secure load holding, install an external rod lock or a pilot-operated check valve.
