Airtac SAUD Double Rod Cylinder SAUD40X50
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X50 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 50mm 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 SAUD40X50
The AirTAC SAUD40X50 is a double-acting, double-rod profile cylinder. A 16 mm rod protrudes from both ends, meaning both faces use the rod-side area. This yields an identical push and pull force of 528 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same 40 mm bore. It uses a 1/4 inch port and M12x1.25 rod threads.
This twin-rod architecture provides rigid anti-twist guidance and lets you drive two tools at once. Based on the 528 N output, the safe working load is about 317 N, which translates to a vertical lift capacity of roughly 27 kg with a 2:1 margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 0-150 C. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD40X50 Is Used
Twin-Tool Stamping
Drives two synchronized stamping heads from one cylinder, ensuring parallel contact without rotational drift.
Dual Transfer Pusher
Pushes a workpiece forward while retracting a second fixture simultaneously at an identical speed.
Balanced Lift Arm
Lifts a 27 kg vertical load with a 2:1 safety margin using equal force in both directions for smooth descent.
Is the Airtac SAUD Double Rod Cylinder SAUD40X50 the Right Cylinder?
Choose this 40 mm bore if you need 528 N of equal bidirectional force. Sizing down, the 32 mm bore gives 345 N both ways. Sizing up, the 50 mm bore provides 825 N both ways. A double rod is the right call for non-rotating loads, twin-tool setups, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this specific SKU lacks the -S magnet, it cannot support magnetic sensing. At a 50 mm stroke, side-load stress is minimal, but for any stroke over 300 mm you should use external guide rails 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 SAUD40X50 FAQ
The force is equal both ways because the 16 mm rod exits both ends. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers.
No, a plain cylinder drifts without live air. The adjustable 21 mm cushions only decelerate the piston near stroke end. To hold a load, install an external rod lock or a pilot-operated check valve.
