Airtac SAUD Double Rod Cylinder SAUD100X70
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X70 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 70mm 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 SAUD100X70
The AirTAC SAUD100X70 is a double-acting, double-rod profile cylinder. A 25mm rod protrudes from both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. Output is therefore equal in extension and retraction, delivering 3681 N each way at 0.5 MPa. The extruded profile body is notably shorter than a standard ISO 15552 unit of the same bore.
This 100mm bore unit features a 1/2 inch port and a 29mm adjustable air cushion at each end. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 degrees 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 SAUD100X70 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools simultaneously from opposite rod ends, ensuring perfectly balanced high-tonnage impact without rotational twist.
Dual-End Diverting
Uses both protruding rods to push and retract diverter gates on parallel packaging lines, maintaining equal clamping force in both directions.
Balanced Pressing Jig
Applies 3681 N of equal downward and upward force to seat heavy components, preventing guide bind during rapid 70mm travel cycles.
Is the Airtac SAUD Double Rod Cylinder SAUD100X70 the Right Cylinder?
When sizing this double-rod unit, compare the 3681 N equal force at 0.5 MPa against the neighboring 80mm bore (2268 N both ways) and the fact that 100mm is the largest available SAUD size. Choose this twin-rod architecture when the application demands strict anti-rotation guidance, synchronized twin-tool driving, or a back-end rod to trip a mechanical switch. Mounting is limited to Basic, FA flange, and LB foot types, matching the AirTAC SC series. Remember that a plain cylinder drifts without live air; the cushion only decelerates near the stroke end, so fit an external rod lock or pilot-operated check valve for 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 SAUD100X70 FAQ
Because the 25mm rod exits both ends, the push and pull forces are equal. This 100mm bore cylinder outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa in both directions. It uses a 1/2 inch port.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG electronic switches. The extended back rod is ideal for tripping external mechanical limit switches instead.
