Airtac SAUD Double Rod Cylinder SAUD63X125
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X125 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 125mm 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 SAUD63X125
The AirTAC SAUD63X125 is a double-acting, double-rod profile cylinder with a 63 mm bore and 125 mm stroke. A rod exits both ends, meaning push and pull forces are equal at 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 inch port and an M16x1.5 rod thread.
This model provides excellent non-rotating anti-twist guidance for twin-tool duty. Since this SKU lacks the -S magnet option, it cannot take a magnetic switch. For sizing, a safe working load is roughly 841 N, allowing a vertical lift of about 71 kg with a 2:1 margin. A Viton H seal option can raise the operating temperature to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X125 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends, delivering 1402 N of equal force to prevent yawning during the press cycle.
Anti-Rotation Transfer
Moves a gripper carriage between stations with strict non-rotating guidance, using the dual rods to resist torsional twist on the payload.
Dual-End Diverters
Actuates sorting flaps on both sides of a belt simultaneously, ensuring packages are pushed cleanly without skewing.
Is the Airtac SAUD Double Rod Cylinder SAUD63X125 the Right Cylinder?
Choose this 63 mm bore when you need 1402 N of equal force in both directions, stepping up from the 50 mm bore which provides 825 N, or down from the 80 mm bore which yields 2268 N. A double rod is the right call for anti-rotation, driving two tools, or mounting a cam on the back end. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. Because this SKU has no -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. At 125 mm stroke, side loads are minimal, but always use external guides for longer reaches. Note that a plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve to hold a load.
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 SAUD63X125 FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It operates on a 3/8 inch port with a speed range of 30-800 mm/s.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the -S variant for position sensing, though you can still use the back rod to trip an external mechanical switch.
