Airtac SAUD Double Rod Cylinder SAUD100X900S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X900S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 900mm 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 SAUD100X900S
The AirTAC SAUD100X900S is a double-acting, double-rod profile cylinder featuring a 100mm bore and a 900mm stroke. Because a rod protrudes from both ends, the working area is identical on each face, yielding an equal push and pull force of 3681N at 0.5MPa. The extruded aluminium body is notably shorter than a conventional 15552 unit of the same bore. This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches.
The 29mm adjustable cushions at both ends manage end-of-stroke deceleration. For environments up to 150C, specify the Viton H seal option.

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 SAUD100X900S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from opposite rod ends, ensuring perfectly balanced cutting feed without rotational twist.
Dual Transfer Pushers
Simultaneously indexes two pallets on parallel conveyors using equal force in both directions for matched cycle times.
Heavy Press Diverter
Handles heavy vertical diverting tasks where the 900mm stroke requires external guides to maintain strict non-rotating accuracy.
Is the Airtac SAUD Double Rod Cylinder SAUD100X900S the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm unit (2268N each way) provides a significant leap in force, while stepping up is unnecessary if 3681N at 0.5MPa is sufficient. A double-rod design is the right call when you need strict anti-rotation guidance, want to drive twin tooling from one piston, or need a back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 900mm, this long stroke demands external guide rails to prevent rod bending and excessive side loading. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so add an external rod lock for load holding.
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 SAUD100X900S FAQ
The force is equal in both directions due to the double-rod design. It outputs 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa. The unit features a 1/2 inch port and operates at speeds of 30-800mm/s.
No, the 29mm adjustable air cushions only decelerate the piston near the stroke ends; they do not act as a brake. If you need to hold a load vertically during air loss, you must install an external rod lock or a pilot-operated check valve.
