Airtac SAUD Double Rod Cylinder SAUD100X45S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X45S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 45mm 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 SAUD100X45S
The AirTAC SAUD100X45S 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 equal push and pull force of 3681 N each way at 0.5 MPa. The unit is shorter than a standard ISO 15552 cylinder of the same 100mm bore, and its 1/2 inch port handles high flow.
Because the rear rod protrudes, it can carry a switch cam or drive a second tool simultaneously. The -S suffix denotes a built-in piston magnet for CMSG, DMSG or EMSG sensors. For high-heat 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 SAUD100X45S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting forces without torsional twist.
Dual Transfer Pushers
Pushes a workpiece forward while the rear rod simultaneously retracts a return conveyor diverter, halving cycle time.
Is the Airtac SAUD Double Rod Cylinder SAUD100X45S the Right Cylinder?
Select this 100mm bore if you need substantial equal-both-ways thrust; stepping down to the 80mm bore drops the force to 2268 N at 0.5 MPa, while no larger standard bore exists in this series. The twin-rod architecture is the right call when you need anti-rotation guidance, synchronized twin-tool driving, or rear-rod switch actuation. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. This 45mm stroke unit is short, so external side-load guides are less critical than on long strokes, but always verify sensor compatibility: the -S magnet enables CMSG/DMSG/EMSG switches, whereas a plain no-S SKU cannot take a sensor.
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 SAUD100X45S FAQ
The force is equal in both directions because a 25mm rod exits both ends. It generates 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 the necessary airflow for these high forces.
No, a plain double-rod cylinder drifts without live air; the adjustable 29mm cushions only decelerate near stroke end. To hold a load securely, fit an external rod lock or a pilot-operated check valve.
