Airtac SAUD Double Rod Cylinder SAUD63X55
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X55 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 55mm 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 SAUD63X55
The AirTAC SAUD63X55 is a double-acting, double-rod profile cylinder featuring a 63 mm bore and a 55 mm stroke. Because a rod protrudes from both ends, the push and pull forces are perfectly equal at 1402 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same bore. It uses a 3/8 inch port and an M16x1.5 rod thread.
This symmetric design provides built-in anti-rotation guidance and allows driving two tools at once. A computed buyer insight: the safe working load is roughly 841 N, yielding a vertical lift capacity of about 71 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X55 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends, ensuring perfectly balanced 1402 N impact force without rotational twist.
Anti-Rotation Transfer
Moves a clamped workpiece between stations with inherent geometric stability, preventing yaw during the 55 mm traverse.
Dual-End Diverting
Actuates sorting flaps on both sides of a belt simultaneously using the twin rods for compact, space-saving automation.
Is the Airtac SAUD Double Rod Cylinder SAUD63X55 the Right Cylinder?
Select this 63 mm bore model when your mechanism requires equal force in both directions, delivering 1402 N at 0.5 MPa. If you need less thrust, step down to the 50 mm bore which provides 825 N both ways. If your application demands more power, the 80 mm bore offers 2268 N. The double-rod architecture is ideal for anti-rotation tasks, mounting twin tooling, or carrying a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this is a non-magnetized SKU, it cannot host position sensors. At a 55 mm stroke, side loads are minimal, but always guide the load externally on longer strokes. Remember that the air cushion only decelerates the piston; it does not hold the load, so add a pilot-operated check valve for vertical safety.
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 SAUD63X55 FAQ
The force is equal in both directions because of 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 inch port feeds both chambers equally to maintain this symmetric thrust.
No, this specific SKU is not magnetized and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for internal sensing, though you can still mount an external switch cam on the back rod.
