Airtac SAUD Double Rod Cylinder SAUD63X400
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X400 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 400mm 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 SAUD63X400
The AirTAC SAUD63X400 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 400mm stroke. Because a rod exits both ends, the push and pull output is identical, delivering 1402 N each way at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It uses a 3/8" port and an M16x1.5 rod thread.
This SKU has no internal magnet, so it cannot host CMSG or DMSG sensors. For thermal extremes, Viton H seals raise the operating limit to 150 C. Based on the 0.5 MPa output, the safe working load is roughly 841 N, translating to a vertical lift capacity of about 71 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD63X400 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with equal 1402 N force, ensuring perfectly synchronized part handoff between machining stations.
Balanced Vertical Lift
Raises and lowers a 71 kg payload with consistent force both up and down, preventing gravitational drift during vertical cycling.
Anti-Rotation Edge Guide
Uses the dual rods to resist torsional twist while positioning long web materials, maintaining precise alignment without external linear bearings.
Is the Airtac SAUD Double Rod Cylinder SAUD63X400 the Right Cylinder?
When sizing this double-rod unit, compare both neighbours: the 50mm bore yields 825 N both ways, while the 80mm bore provides 2268 N. Choose this 63mm model when you need symmetrical force for anti-rotation guidance, twin tooling, or driving a cam on the back rod. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. Because the 400mm stroke invites rod bending, fit external guide rails to handle side loads. As a non-magnet SKU, sensing is unsupported.
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 SAUD63X400 FAQ
The force is equal in both directions due to the double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The 3/8" port and M16x1.5 rod thread are standard for this 63mm bore.
No. A plain double-rod cylinder drifts without live air; the adjustable 21mm cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
