Airtac SAUD Double Rod Cylinder SAUD63X45
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X45 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 45mm 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 SAUD63X45
The AirTAC SAUD63X45 is a double-acting, double-rod profile cylinder with a 63mm bore and 45mm stroke. Because a rod extends from both ends, the push and pull output is identical at 1402 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore. This standard SKU lacks a magnet, so it cannot host CMSG or DMSG sensors.
This compact unit uses a 3/8 inch port and an M16x1.5 rod thread. With 1402 N of equal force, your safe working load is roughly 841 N, yielding a vertical lift capacity of about 71 kg with a 2:1 margin. For high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X45 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from one piston, ensuring perfectly synchronized part handling without adding a second actuator.
Anti-Rotation Lift
Lifts delicate electronics trays with equal push and pull force, using the dual rods to prevent twist and maintain precise vertical alignment.
Symmetric Clamping
Clamps a workpiece from both sides evenly, using the identical 1402 N force in both directions to balance machining loads.
Is the Airtac SAUD Double Rod Cylinder SAUD63X45 the Right Cylinder?
Choose this 63mm bore delivering 1402 N both ways when you need strict anti-rotation guidance or twin tooling. If your project requires less thrust, the 50mm bore provides 825 N both ways; if you need more, step up to the 80mm bore for 2268 N. Mounting is limited to Basic, FA flange, or LB foot styles matching the AirTAC SC series. Since this 45mm stroke is short, side-load stress is minimal. Note that this non-magnetic version cannot accept 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 SAUD63X45 FAQ
The double-rod design yields equal force in both directions: 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. The air cushions only decelerate the piston near stroke ends; they do not act as a brake. For load holding on air loss, you must fit an external rod lock or a pilot-operated check valve.
