About the Airtac SAUD Double Rod Cylinder SAUD50X170S
The AirTAC SAUD50X170S is a double-acting, double-rod profile cylinder featuring a 50mm bore and 170mm stroke. A piston rod protrudes from both ends, meaning both faces use the rod-side area to deliver an identical output of 825 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This unit includes the -S magnet option for CMSG, DMSG, or EMSG switches. You can mount a sensor cam or trip a switch on the back rod. Based on the 825 N output, the safe working load is roughly 495 N, and it can vertically lift about 42 kg with a 2:1 margin. The 1/4" port, Viton H high-temp seal option, and adjustable cushions add engineering flexibility.

Where the Airtac SAUD Double Rod Cylinder SAUD50X170S Is Used
Twin-Tool Machining
Drives two opposing machining heads simultaneously with equal 825 N force, ensuring perfectly synchronized part processing.
Non-Rotating Lift
Lifts delicate electronics trays vertically without twist, using the dual rods to prevent piston rotation during travel.
Dual-End Sensing
Operates a primary work clamp on the front rod while using the back rod to physically trigger a CMSG limit sensor.
Is the Airtac SAUD Double Rod Cylinder SAUD50X170S the Right Cylinder?
Choose this 50mm bore when you need 825 N of equal bidirectional force. Sizing down, the 40mm bore provides 528 N both ways. Sizing up, the 63mm bore yields 1402 N each way. A double-rod design is the right call for anti-rotation guidance, driving twin tooling, or back-end sensing. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. The -S magnet enables switch tracking. At 170mm stroke, side-load is moderate, but always use external guides for any stroke over 300mm.
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 SAUD50X170S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4" port supplies air to both chambers.
No, a plain cylinder drifts without live air. The adjustable cushions only decelerate the piston near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
