Airtac SAUD Double Rod Cylinder SAUD40X75
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X75 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 75mm 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 SAUD40X75
The AirTAC SAUD40X75 is a double-acting, double-rod profile cylinder. A 16mm rod exits both ends, meaning push and pull forces are equal at 528 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same 40mm bore.
Because both faces use the rod-side area, the output is identical in both directions. This yields a safe working load of about 317 N and a vertical lift capacity near 27 kg with a 2:1 margin. The 1/4" port and M12x1.25 rod thread are fixed by the bore. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD40X75 Is Used
Twin-Tool Transfer
Drives two opposing pick-and-place heads simultaneously, ensuring perfectly synchronized grip and release cycles.
Anti-Rotation Lift
Lifts delicate electronic trays without twisting, using the dual rods to maintain strict parallel guidance.
Symmetric Clamping
Applies identical 528 N clamping pressure from both sides to hold a workpiece centered during machining.
Is the Airtac SAUD Double Rod Cylinder SAUD40X75 the Right Cylinder?
Choose this 40mm bore when you need equal 528 N force in both directions for anti-rotation or twin-tool tasks. If you need less force, the 32mm bore provides 345 N both ways; for more power, the 50mm bore offers 825 N. Mounting is limited to Basic, FA flange, or LB foot styles compatible with the AirTAC SC series. The 75mm stroke is short enough to avoid side-load guide issues. Remember this non-magnet SKU cannot support switches.
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 SAUD40X75 FAQ
The force is equal in both directions due to the double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4" port supplies air to both chambers.
No. The air cushions only decelerate the piston near the stroke end; they do not lock the load. If pressure is lost, the piston drifts. Use an external rod lock or pilot-operated check valve for secure load holding.
