Airtac SAUD Double Rod Cylinder SAUD100X145S
The AirTAC SAUD Double Rod Cylinder SAUD100X145S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 145mm 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 SAUD100X145S
The AirTAC SAUD100X145S is a double-acting, double-rod profile cylinder with a 100mm bore and 145mm stroke. A piston rod protrudes from both ends, meaning both faces use the identical rod-side area. This yields perfectly balanced thrust of 3681 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel is noticeably shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, M20x1.5 rod threads, and 29mm adjustable air cushions at each end.
Because the -S suffix indicates a built-in piston magnet, this unit is ready for CMSG, DMSG, or EMSG switches. The twin rods provide rigid anti-rotation guidance and allow driving two tools simultaneously. For high-temperature environments up to 150 C, 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 SAUD100X145S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly matched feed rates on both ends of the workpiece.
Dual Transfer Arms
Powers opposing transfer arms that move parts simultaneously across a conveyor belt without twisting or rotational play.
Symmetric Lifting Jigs
Lifts heavy pallets or fixtures evenly using both rod ends, maintaining parallel alignment during vertical elevation.
Is the Airtac SAUD Double Rod Cylinder SAUD100X145S the Right Cylinder?
Select this 100mm bore model when your application demands high equal force both ways alongside strict anti-rotation stability. It generates 3681 N in both directions. If you need less force, the 80mm bore provides 2268 N; if you require more, note that 100mm is the largest available in this series. The 145mm stroke falls well under the 1500mm maximum, so standard side-load guidance rules are relaxed, though external guides always help maximize bearing life. Mounting is limited to Basic, FA flange, and LB foot styles, matching AirTAC SC series dimensions. The -S magnet allows solid state or reed sensors to track position. Remember that air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve if you need to hold a load securely during air loss.
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 SAUD100X145S FAQ
The force is equal in both directions because it is a double-rod design. It outputs 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 the resulting flow.
The twin rods prevent rotation and allow you to mount a sensor cam or drive a second tool on the back rod. The -S magnet enables CMSG, DMSG, or EMSG switches for precise end-of-stroke detection.
