Airtac SAUD Double Rod Cylinder SAUD63X70
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X70 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 70mm 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 SAUD63X70
The AirTAC SAUD63X70 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 70mm 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 unit of the same bore.
This model uses a 3/8 inch port and offers a safe working load of roughly 841 N, translating to a vertical lift capacity of about 71 kg with a 2:1 margin. Note this 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 SAUD63X70 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends, ensuring perfectly balanced 1402 N impact without rotational twist.
Dual-Side Diverting
Pushes a product lane guide from either direction, using the equal force both ways to reposition items accurately on a packaging line.
Anti-Rotation Lift
Raises and lowers a 71 kg vertical fixture smoothly, relying on the dual rods to prevent rack twisting during the 70mm travel.
Is the Airtac SAUD Double Rod Cylinder SAUD63X70 the Right Cylinder?
Choose this 63mm bore when you need 1402 N of equal bi-directional force; step down to the 50mm bore for 825 N, or up to the 80mm bore for 2268 N. The twin rods provide excellent anti-rotation guidance and allow driving two tools simultaneously. Mounting is limited to Basic, FA flange, and LB foot styles compatible with the AirTAC SC series. Since this specific SKU has no internal magnet, you cannot mount position switches. At a 70mm stroke, side loads are minimal, but always guide the load externally on longer strokes. Remember that air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve to hold a load securely on air loss.
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 SAUD63X70 FAQ
The force is equal in both directions because it is a double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. You would need the -S suffix version for switch readiness.
