Airtac SAUD Double Rod Cylinder SAUD50X500S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X500S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 500mm stroke, 1/4" 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 SAUD50X500S
The AirTAC SAUD50X500S is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning the push and pull output is identical at 825 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" port and M16x1.5 rod thread.
Because the rod exits both faces, the rear shaft can carry a switch cam to trip a sensor. This -S model includes a piston magnet for CMSG, DMSG, or EMSG switches. Based on the 825 N output, the safe working load is roughly 495 N, allowing a vertical lift of about 42 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 SAUD50X500S Is Used
Twin-Tool Transfer
Drives two synchronized work tools from opposite rod ends to cut cycle time in half on packaging lines.
Cam-Triggered Sorting
Uses the extended back rod as a switch cam to trip a CMSG sensor, confirming full stroke position.
Anti-Rotation Clamping
Provides non-rotating, twist-resistant clamping force on machined parts without external guides.
Is the Airtac SAUD Double Rod Cylinder SAUD50X500S the Right Cylinder?
When sizing this double-rod unit, compare both ways: the 40 mm bore yields 528 N each way, while the 63 mm bore provides 1402 N. Choose the 50 mm for anti-rotation guidance, twin-tool driving, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. For the 500 mm stroke, external guides are recommended to prevent rod bending under side loads. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for load holding, as cushions only decelerate.
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 SAUD50X500S FAQ
The force is equal both ways due to the double-rod design. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4" port and 20 mm rod ensure consistent push and pull thrust.
The dual-rod design prevents piston rotation and allows the rear shaft to drive a second tool or carry a sensor cam. The extruded profile barrel is also shorter than an ISO 15552 cylinder of the same 50 mm bore.
