Airtac SAUD Double Rod Cylinder SAUD63X325
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X325 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 325mm 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 SAUD63X325
The AirTAC SAUD63X325 is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning push and pull forces are identical at 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 has a 3/8 inch port and M16x1.5 rod threads.
This 63 mm bore model delivers a safe working load of roughly 841 N, or a vertical lift capacity of about 71 kg with a 2:1 margin. The twin-rod design provides anti-rotation guidance for non-twist duty. Note this SKU lacks a magnet, so it cannot take CMSG or DMSG sensors. For high heat up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X325 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, keeping force balanced at 1402 N per side for matched pressing.
Anti-Rotation Diverter
Uses the dual rods to prevent twist during fast lane-changing strokes, ensuring the guide face stays perfectly aligned.
Dual-End Lift Gate
Lifts a 71 kg vertical load using both rod ends to push and pull symmetrically without sagging or uneven wear.
Is the Airtac SAUD Double Rod Cylinder SAUD63X325 the Right Cylinder?
Choose this 63 mm bore delivering 1402 N equal force both ways at 0.5 MPa. Stepping down, the 50 mm bore gives 825 N, while stepping up, the 80 mm bore provides 2268 N. A double rod is the right call when you need anti-rotation stability, twin tooling, or a back-end cam. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. Because the 325 mm stroke is long, add external guide rails to prevent rod bending under side loads. This SKU has no magnet, so it cannot host position sensors.
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 SAUD63X325 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa on both the push and pull strokes.
No. This specific SAUD63X325 SKU is built without a piston magnet, so it cannot host CMSG, DMSG, or EMSG reed switches. You must specify a -S suffix model to enable magnetic sensing.
