Airtac SAUD Double Rod Cylinder SAUD100X275S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X275S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 275mm 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 SAUD100X275S
The AirTAC SAUD100X275S 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 each way at 0.5 MPa. The unit carries the -S suffix, so a built-in piston magnet is present for CMSG, DMSG or EMSG reed and electronic switches.
Because the second rod spans the full 275mm stroke, it serves as an excellent cam for rear-mounted sensors or drives twin tooling simultaneously. This profile body is noticeably shorter than an ISO 15552 unit of the same 100mm bore. The 1/2 inch port feeds air efficiently, and a Viton H seal option can push the operating ceiling from 70 C up 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 SAUD100X275S Is Used
Twin-Spindle Machining
Drives two opposing machining heads with identical 3681 N force, using the dual rods to maintain strict parallelism without rotational twist.
Dual Transfer Arms
Powers synchronized pick-and-place arms at both ends, ensuring parts move across the belt at an identical pace and distance.
Vertical Lift Fixture
Hoists a 188 kg payload vertically using the equal pull force, relying on the second rod to mount a rear position cam for tracking.
Is the Airtac SAUD Double Rod Cylinder SAUD100X275S the Right Cylinder?
Select this 100mm bore if your application demands high equal force in both directions. Step down to the 80mm bore for 2268 N, or step up if you need more than the 3681 N provided here. A double rod is the right call when you need anti-rotation guidance, synchronized twin tooling, or a rear surface to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 275mm stroke, external guide rails are recommended to prevent side-load sagging. Note that a plain cylinder drifts on air loss; the 29mm adjustable cushions only decelerate near the ends, so add an external rod lock or pilot-operated check valve for secure 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 SAUD100X275S FAQ
The force is equal in both directions because a rod exits both ends. 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 supplies air to achieve these figures.
The dual rods provide anti-rotation accuracy and allow you to mount CMSG or DMSG sensors on the back rod. The -S suffix guarantees the magnet is pre-installed for immediate switch integration.
