The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X45 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 45mm 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.
The AirTAC SAUD40X45 is a double-acting, double-rod profile cylinder featuring a 40 mm bore and a 45 mm stroke. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields exactly 528 N of output force at 0.5 MPa in both directions. The extruded hard-anodized aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore.
Because of the twin-rod architecture, the rear extension can drive a second tool or act as a cam. This specific SKU lacks the -S magnet option, so it cannot host CMSG or DMSG reed sensors. Operating speed spans 30-800 mm/s, and the 1/4" port drives air efficiently. For sizing, a safe working load is roughly 317 N (60% of the 528 N figure), translating to a 27 kg vertical lift capacity with a 2:1 safety margin.

Drives two synchronized pick-and-place grippers simultaneously from a single compact body, ensuring perfectly matched timing without external linkages.
Lifts light platforms up to 27 kg vertically with inherent twist resistance, preventing the load from rotating during transit without external linear bearings.
Uses the protruding rear rod to mechanically trip a limit switch at mid-stroke, providing a hard mechanical position signal independent of pneumatic sensors.
Choose this 40 mm bore if you need 528 N of equal bidirectional thrust at 0.5 MPa. Stepping down to a 32 mm bore drops the equal force to 345 N, while stepping up to a 50 mm bore raises it to 825 N. A double-rod design is the right call when your mechanism demands anti-rotation guidance, synchronized twin-tool driving, or needs a rear extension to trip an external switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Since this SKU lacks a magnet, you cannot mount magnetic sensors. At a 45 mm stroke, side loads are minimal, but always use external guides for longer strokes over 300 mm.
Quick checklist
The force is equal in both directions because it is a double-rod cylinder. 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 and 16 mm rod ensure balanced thrust on both strokes.
No, the adjustable 21 mm air cushions only decelerate the piston near the stroke ends; they do not act as a brake. For load holding, you must install an external rod lock or a pilot-operated check valve.
