Airtac SAUD Double Rod Cylinder SAUD40X150
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X150 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 150mm 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 SAUD40X150
The AirTAC SAUD40X150 is a double-acting, double-rod profile cylinder. A 16 mm rod exits both ends, meaning both faces use the rod-side area and output force is equal both ways at 528 N at 0.5 MPa. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same 40 mm bore. It features a 1/4 inch port and M12x1.25 rod threads.
This SKU has no magnet (-S omitted), so it cannot take a magnetic switch. For sizing, the safe working load is roughly 317 N (about 60 percent of the 528 N figure), translating to a vertical lift capacity of about 27 kg with a 2:1 margin. You can specify Viton H seals to raise the operating temperature from -20 to +70 C up to 0-150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X150 Is Used
Twin Tool Transfer
Drives two synchronized work heads from one piston, keeping force balanced at 528 N on both extension and retraction.
Anti-Rotation Jig
Dual rods prevent mechanical twist during clamping, ensuring the jig stays perfectly aligned through the 150 mm travel.
Dual-End Pick Place
Carries a gripper on the front rod and a cam on the back rod to trip a mechanical limit switch without extra sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD40X150 the Right Cylinder?
Choose this 40 mm bore if you need 528 N of equal push and pull force at 0.5 MPa. Sizing up to the 50 mm bore gives 825 N, while dropping to the 32 mm bore provides 345 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. At a 150 mm stroke, side loads are minimal, but external guides are recommended for longer strokes. Because this SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors.
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 SAUD40X150 FAQ
Because it is a double-rod cylinder, the force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It uses a 1/4 inch port.
No. The adjustable air cushion only decelerates the piston near stroke end. For a held load on air loss, you must add an external rod lock or pilot-operated check valve.
