The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X90 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 90mm 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 SAUD40X90 is a double-acting, double-rod profile cylinder. A 16mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields an equal output force of 528 N each way at 0.5 MPa through its 1/4" port. The extruded profile body is noticeably shorter than a standard ISO 15552 unit of the same bore.
Because the twin rods prevent twist, this 90mm stroke model suits synchronized driving and twin-tool duties. A computed buyer insight: the safe working load is roughly 317 N, allowing a vertical lift of about 27 kg with a 2:1 safety margin. Note this base SKU lacks a magnet, so it cannot host CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

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 parallel pickers simultaneously, keeping stroke perfectly synchronized without adding an external shaft.
Raises and lowers a 27 kg vertical load with equal push and pull force, preventing rotational drift during travel.
Uses the protruding back rod to mechanically trip a limit valve at stroke end, independent of internal sensors.
When sizing this double-rod unit, compare both ways: the 32mm bore provides 345 N equal force, while the 50mm bore offers 825 N. Choose this 40mm bore when your mechanism needs strict anti-rotation guidance, drives two tools at once, or requires a back rod to trip an external switch. Mounting is limited to Basic, FA flange, or LB foot styles matching the AirTAC SC series. At 90mm stroke, side loads are minimal, but always guide the load externally on longer travels. Remember this specific SKU has no magnet (-S), so electronic position sensing is unavailable.
Quick checklist
The force is equal in both directions because of 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 and 16mm rod ensure these figures match on both the extend and retract strokes.
No. A plain double-rod cylinder drifts without live air, as the adjustable cushions only decelerate near the end of stroke. To maintain a vertical position, install an external rod lock or a pilot-operated check valve.
