Airtac SAUD Double Rod Cylinder SAUD50X25S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X25S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 25mm 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 SAUD50X25S
The AirTAC SAUD50X25S is a double-acting, double-rod profile cylinder. Because a rod exits both ends, the push and pull output is identical, delivering 825 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore. This -S variant includes a piston magnet for position sensing.
With a 50 mm bore, 20 mm rod, and 1/4" port, it yields a safe working load of roughly 495 N. This equates to a vertical lift capacity of about 42 kg with a 2:1 safety margin. The rear protruding rod is perfect for mounting a switch cam or driving twin tooling synchronously.

Where the Airtac SAUD Double Rod Cylinder SAUD50X25S Is Used
Twin-Tool Transfer
Drives two opposing pickers simultaneously so parts move in perfect sync without twist.
Cam-Triggered Clamping
Uses the rear rod extension to trip an external limit switch for precise clamp verification.
Balanced Lift Station
Raises and lowers a 42 kg payload vertically with equal force and stable anti-rotation control.
Is the Airtac SAUD Double Rod Cylinder SAUD50X25S the Right Cylinder?
Choose this 50 mm bore when you need 825 N of equal bidirectional force. If your project requires less thrust, the 40 mm bore provides 528 N both ways; for heavier drives, step up to the 63 mm bore for 1402 N. The double-rod architecture is ideal for anti-rotation guidance and carrying a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The built-in -S magnet supports CMSG, DMSG, and EMSG switches. At a 25 mm stroke, side loads are minimal, but always guide external mechanisms 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 SAUD50X25S FAQ
The force is equal in both directions due to the double-rod design. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4" port supplies air to both chambers.
No. The air cushions only decelerate the piston near stroke end; they do not lock the position. To prevent drift on air loss, you must fit an external rod lock or pilot-operated check valve.
