Airtac SAUD Double Rod Cylinder SAUD100X155S
The AirTAC SAUD Double Rod Cylinder SAUD100X155S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 155mm 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 SAUD100X155S
The AirTAC SAUD100X155S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side area. This yields exactly 3681 N of thrust and pull at 0.5 MPa, so output force is identical in both directions. The unit is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod extends out the back, you can mount a switch cam directly on it. This -S variant includes a piston magnet for CMSG, DMSG, or EMSG sensors. The 1/2" port feeds the chambers, while adjustable 29 mm cushions decelerate the load at each end. For high-heat duties up to 150 C, specify the Viton H seal.

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 SAUD100X155S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting feed without rotational twist.
Dual Pusher Array
Pushes cartons from both ends of a transfer line simultaneously, using the equal force to keep items square during diversion.
Balanced Press Lift
Raises and lowers a 188 kg press platen vertically, relying on the matched thrust and pull to prevent binding in the guides.
Is the Airtac SAUD Double Rod Cylinder SAUD100X155S the Right Cylinder?
Choose this 100 mm bore when you need 3681 N of equal bidirectional force at 0.5 MPa. If your application is lighter, the 80 mm bore provides 2268 N both ways. If you need more power, no larger standard SAUD bore exists, so you would parallel two cylinders. A double-rod design is the right call for anti-rotation guidance, driving twin tooling, or tripping a rear-mounted sensor. Mounting is limited to Basic, FA flange, or LB foot styles, matching the AirTAC SC series. At a 155 mm stroke, side loading is minimal, but always use external guide rails for any stroke over 300 mm. The -S magnet enables electronic or reed 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 SAUD100X155S FAQ
Force is equal both ways because rods exit 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" port supplies air to achieve these thrust and pull figures.
No, the piston drifts without live air. The 29 mm cushions only decelerate near stroke end. For load holding, add an external rod lock or pilot-operated check valve. The -S magnet works with CMSG/DMSG/EMSG sensors for position tracking.
