Airtac SAUD Double Rod Cylinder SAUD63X120
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X120 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 120mm 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 SAUD63X120
The AirTAC SAUD63X120 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 120mm stroke. Because a rod protrudes from both ends, the push and pull forces are identical, delivering 1402 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It uses a 3/8" port and adjustable 21mm air cushions at both ends.
This unit lacks the -S magnet option, so it cannot accept CMSG or DMSG magnetic switches. For sizing, the safe working load is roughly 841 N (about 60% of the 0.5 MPa force), translating to a vertical lift capacity of approximately 71 kg with a 2:1 safety margin. A Viton H seal upgrade allows operation up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X120 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with equal 1402 N force, ensuring perfectly synchronized part handoff between machining stations.
Anti-Rotation Lift
Lifts vertical jigs up to 71 kg without twisting, using the inherent geometric stability of the dual-rod architecture to maintain precise alignment.
Cam-Actuated Cutting
Powers a front cutting blade while the extended back rod trips an external mechanical limit switch to confirm stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD63X120 the Right Cylinder?
Choose this 63mm bore (1402 N equal force) if you need twin-tool synchronization or back-rod cam actuation. Sizing down, the 50mm bore yields 825 N both ways; sizing up, the 80mm bore provides 2268 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 120mm stroke, side loads are minimal, but always guide the load externally for rigid assemblies. Remember this non-magnet SKU cannot host 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 SAUD63X120 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.
No, the air cushions only decelerate the piston near the stroke ends; they do not lock the load. To prevent drift on air loss, you must fit an external rod lock or a pilot-operated check valve.
