Airtac SAUD Double Rod Cylinder SAUD100X425
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X425 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 425mm 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 SAUD100X425
The AirTAC SAUD100X425 is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields equal output force in both directions, delivering 3681 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than a standard ISO 15552 cylinder of the same 100mm bore.
This unit features a 1/2 inch port and M20x1.5 rod threads. Because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensors. A Viton H seal option raises the operating ceiling 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 SAUD100X425 Is Used
Synchronized Lift Station
Drives a rigid lifting platform from both ends to prevent platform twist during vertical elevation of heavy assemblies.
Dual-Tool Machining Fixture
Carries a machining tool on the front rod and a secondary clamp on the back rod to actuate two separate operations in one stroke.
Heavy Pallet Transfer
Shifts loaded pallets laterally using equal push and pull forces, ensuring consistent momentum control in both travel directions.
Is the Airtac SAUD Double Rod Cylinder SAUD100X425 the Right Cylinder?
Size both ways: the 100mm bore gives 3681 N both ways, while the smaller 80mm bore yields 2268 N. Choose this double-rod model when you need anti-rotation guidance, twin tooling, or a back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. Because the 425mm stroke is long, use external guides to prevent rod bending and side loads. Note that this non-magnetic SKU cannot hold a load without live air; the cushion only decelerates, so add an external rod lock for vertical safety.
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 SAUD100X425 FAQ
The force is equal in both directions because it is a double-rod cylinder. It produces 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.
No. This specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. If you require position sensing, select an SAUD model with the -S suffix.
