Airtac SAUD Double Rod Cylinder SAUD100X350S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X350S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 350mm 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 SAUD100X350S
The AirTAC SAUD100X350S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 3681 N of thrust and pull at 0.5 MPa, ensuring perfectly symmetrical force. The 1/2 inch port feeds the 100mm bore, and the unit is notably shorter than a conventional ISO 15552 cylinder of the same size.
Because the rear rod protrudes, it readily carries a switch cam for position sensing. This specific SKU includes the -S magnet for CMSG, DMSG, or EMSG sensors. A 29mm adjustable air cushion decelerates the piston at both ends, though external guides are strongly advised for this 350mm stroke to prevent rod bending under side loads.

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 SAUD100X350S Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with equal 3681 N force, ensuring balanced material removal on both sides of a workpiece.
Rear-Cam Sensing
Utilizes the protruding back rod to trip a CMSG or DMSG switch, ideal for tight spaces where front-end sensors would collide with the primary work area.
Is the Airtac SAUD Double Rod Cylinder SAUD100X350S the Right Cylinder?
Select this 100mm bore actuator when your mechanism demands identical push and pull forces, such as twin-tool machining or non-rotating lift rigs. If you need less power, the 80mm bore delivers 2268 N both ways at 0.5 MPa; stepping up is not possible as 100mm is the largest in the series. Mounting is limited to Basic, FA flange, and LB foot styles, matching AirTAC SC series hole patterns. The included -S magnet allows solid state or reed switch mounting on the profile slot. Because the 350mm stroke creates leverage that amplifies side loads, always use external linear guides to protect the seals and prevent rod bending.

- ✓ 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 SAUD100X350S FAQ
The force is equal in both directions because the 25mm 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 and 29mm cushions handle these loads effectively.
No, a standard double-acting cylinder drifts when air is removed or the valve is centered. The adjustable cushions only decelerate the piston near the stroke ends; they do not lock it. For secure load holding, install an external rod lock or pilot-operated check valve.
