Airtac SAUD Double Rod Cylinder SAUD100X120
The AirTAC SAUD Double Rod Cylinder SAUD100X120 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 120mm 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 SAUD100X120
The AirTAC SAUD100X120 is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends, meaning both faces use the rod-side piston area. This yields exactly 3681 N of thrust and pull at 0.5 MPa. The extruded aluminium body is noticeably shorter than a standard ISO 15552 unit of the same 100mm bore.
Because the rear rod protrudes, you can mount a cam directly on it to trip external limit switches. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. The 1/2 inch port matches the bore size.

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 SAUD100X120 Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with equal force in both directions, ensuring balanced material removal.
Balanced Vertical Lift
Raises and lowers a 188kg platen using the equal push and pull forces, preventing gravity-induced drift during direction changes.
Reciprocating Transfer
Pushes and pulls a shuttle carriage between two conveyors, using the rear rod extension to trigger external mechanical stops.
Is the Airtac SAUD Double Rod Cylinder SAUD100X120 the Right Cylinder?
Choose this 100mm bore when your application demands identical push and pull forces, such as driving twin tooling or preventing rotation without external guides. If you need less force, step down to the 80mm bore (2268 N both ways); if you need more, this is the largest available SAUD size. Mounting is limited to Basic, FA flange, or LB foot styles, matching the AirTAC SC series. Because this unit lacks the -S magnet, position sensing requires external mechanical switches on the rear rod. For any stroke over 300mm, ensure external load guides are used to prevent side-loading damage.
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 SAUD100X120 FAQ
The force is equal in both directions because of the 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 feeds both chambers equally.
No. The adjustable 29mm air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston will drift. Use an external rod lock or pilot-operated check valve for load holding.
