Airtac SAUD Double Rod Cylinder SAUD63X40S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X40S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 40mm 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 SAUD63X40S
The AirTAC SAUD63X40S is a double-acting, double-rod profile cylinder. A rod exits both ends on one piston, meaning both faces use the rod-side area. Push and pull force are equal, delivering 1402 N each way at 0.5 MPa. The 3/8" port and M16x1.5 rod thread handle the airflow and mounting. This extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the magnet is present (-S), you can mount CMSG, DMSG, or EMSG switches directly. The rear rod is perfect for carrying a sensor cam or tripping a switch. For a safe working load, expect roughly 841 N, which allows a vertical lift of about 71 kg with a 2:1 margin. The standard TPU seals handle -20 to +70 C, while a Viton H option raises heat resistance to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X40S Is Used
Twin Tool Driving
Drives two opposing forming tools simultaneously with equal 1402 N force, keeping cycle times synchronized.
Anti-Rotation Guidance
The dual rods prevent piston twist during clamping, ensuring precise vertical alignment for thin workpieces.
Rear Cam Sensing
Uses the protruding back rod to trip an external limit switch, providing a physical backup to the magnetic sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD63X40S the Right Cylinder?
Choose this 63 mm bore when you need 1402 N of equal force in both directions. If you need less power, step down to the 50 mm bore for 825 N; if you need more, step up to the 80 mm bore for 2268 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. The built-in magnet supports reed and electronic sensors. Since the stroke is only 40 mm, side-load stress is minimal, but always guide external loads to prevent binding.
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 SAUD63X40S FAQ
Force is equal both ways because both faces lose rod area. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The 3/8" port feeds this power.
No. A plain cylinder drifts without live air; the adjustable cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for load holding.
