The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X30 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 30mm 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 SAUD40X30 is a double-acting, double-rod profile cylinder with a 40 mm bore and 30 mm stroke. A rod protrudes from both ends, meaning the push and pull forces are identical at 528 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore, and mounting parts match the AirTAC SC series.
This SKU has no magnet (-S omitted), so it cannot accept CMSG or DMSG sensors. The 1/4" port drives the unit at 30-800 mm/s. Based on the 528 N output, the safe working load is roughly 317 N, yielding a vertical lift capacity of about 27 kg with a 2:1 margin. Note that the 21 mm cushions only decelerate the piston; an external rod lock is needed to hold a load.

Related SAU-family variants: SAUD (double rod), SAUJ (adjustable stroke), SAUF (with built-in solenoid valve), and SAU-S with built-in magnet. Seals: TPU (blank) / Viton H / NBR N. Sensor switches: CMSG / DMSG / EMSG.
Drives two opposing grippers simultaneously using both rod ends to pick and place parts on a short 30 mm stroke.
Uses the equal push and pull forces to center workpieces from both sides without rotational deflection.
Ejects machined aluminum parts from a fixture with a compact 40 mm profile body that fits tight cells.
Choose this 40 mm bore delivering 528 N each way when you need synchronized motion or anti-twist guidance. If you need less force, step down to the 32 mm bore (345 N both ways); for more power, step up to the 50 mm bore (825 N both ways). Mounting is limited to Basic, FA, and LB styles. If you require position feedback, select the -S magnet version instead of this plain unit. For this 30 mm stroke, side loads are minimal, but any stroke over 300 mm demands external guide rails to prevent binding.
Quick checklist
Because it is a double-rod cylinder, the force is equal in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It uses a 1/4" port.
No, this specific SKU lacks the internal magnet (-S option) required for CMSG, DMSG, or EMSG switches. You must order the -S version for sensor compatibility.
