Airtac SAUD Double Rod Cylinder SAUD63X80
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X80 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 80mm stroke, 3/8" 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 SAUD63X80
The AirTAC SAUD63X80 is a double-acting, double-rod profile cylinder with a 63 mm bore and 80 mm stroke. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields exactly 1402 N of output force at 0.5 MPa in both directions. The extruded aluminum barrel keeps the total length shorter than a standard ISO 15552 unit of the same bore. It uses a 3/8 inch port and an M16x1.5 rod thread.
Because the second rod prevents piston rotation, this model is ideal for anti-twist guidance and driving twin tooling. A practical computed insight: the safe working load is roughly 841 N, and it can vertically lift about 71 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 C, you can specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X80 Is Used
Twin-Tool Stamping
Drives two matched forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized contact on the workpiece.
Anti-Rotation Diverter
Pushes a sorting flap on a packaging line without twisting, relying on the dual rods for strict rotational stability.
Balanced Lift Fixture
Raises and lowers a machining fixture with equal force both up and down, preventing sagging from unequal chamber areas.
Is the Airtac SAUD Double Rod Cylinder SAUD63X80 the Right Cylinder?
Choose this 63 mm bore when your application demands equal 1402 N force both ways at 0.5 MPa. If you need less thrust, step down to the 50 mm bore which provides 825 N both ways. If you require more power, step up to the 80 mm bore delivering 2268 N. A double-rod design is the right call for synchronized twin-tool driving or strict anti-rotation needs. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Since this 80 mm stroke is under 300 mm, side-load stress is minimal, but always guide the load externally on longer travels. Note that this non-magnetic version cannot host position switches.
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 SAUD63X80 FAQ
The force is equal in both directions because it is a double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It never produces a larger single-rod push value.
No, a plain SAUD cylinder does not hold a load without live air; the piston will drift and the adjustable cushions only decelerate near stroke end. For a held load, you must add an external rod lock or a pilot-operated check valve.
