Airtac SAUD Double Rod Cylinder SAUD50X155S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X155S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 155mm 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 SAUD50X155S
The AirTAC SAUD50X155S is a double-acting profile cylinder with a rod extending from both ends. This design yields equal output in both directions, delivering 825 N each way at 0.5 MPa through its 1/4 inch port. The extruded aluminum body is shorter than a standard ISO 15552 unit of the same bore.
Because the piston rod exits both faces, the effective area is identical on push and pull strokes. This makes the unit ideal for synchronized motion or carrying a switch cam on the back rod. The integrated magnet (-S) supports CMSG, DMSG, or EMSG sensors. Based on the 825 N figure, the safe working load is roughly 495 N, translating to a vertical lift capacity of about 42 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD50X155S Is Used
Twin-Tool Transfer
Drives two opposing pick-and-place heads simultaneously with identical 825 N force, ensuring perfectly synchronized part handling.
Cam-Operated Sensing
Uses the protruding back rod to physically trip a limit switch or carry a CMSG sensor cam, providing precise end-of-stroke confirmation.
Anti-Rotation Clamping
Applies equal clamping pressure from both directions to prevent workpiece twist during machining or gluing operations.
Is the Airtac SAUD Double Rod Cylinder SAUD50X155S the Right Cylinder?
When sizing this double-rod unit, compare it with neighboring bores: the 40 mm version provides 528 N both ways, while the 63 mm offers 1402 N at 0.5 MPa. Choose this 50 mm model when your application demands anti-rotation guidance, twin-tool driving, or back-end sensing. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. The -S suffix ensures compatibility with CMSG, DMSG, and EMSG switches. Since the 155 mm stroke is under 300 mm, side-load risks are minimal, but external guides are always recommended for rigid payloads.
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 SAUD50X155S FAQ
The force is equal in both directions because the rod exits both ends. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The unit uses a 1/4 inch port and operates at 30-800 mm/s.
No, the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston will drift. For secure load holding, you must install an external rod lock or a pilot-operated check valve.
