The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X220S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 220mm 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 SAUD40X220S is a double-acting, double-rod profile cylinder with a 40 mm bore and 220 mm stroke. A rod exits both ends, meaning both faces use the rod-side area. Output force is equal in both directions, delivering 528 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. This unit includes a 1/4" port and an M12x1.25 rod thread.
Because the -S suffix denotes a built-in piston magnet, this model supports CMSG, DMSG, and EMSG switches for position sensing. The rear protruding rod can also carry a cam to trip external limit switches or drive twin tooling. Based on the 528 N output, the computed safe working load is roughly 317 N, which translates to a vertical lift capacity of about 27 kg with a 2:1 safety margin. A Viton H seal option raises the operating ceiling from 70 C to 150 C.

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 work heads simultaneously from one piston, ensuring perfectly matched timing without complex linkages.
Uses the extended back rod to carry a switch cam, providing a mechanical trigger for external position sensors.
The twin rods resist torsional twist during clamping or lifting, maintaining precise angular alignment of the payload.
Select this 40 mm bore when your application demands equal push and pull thrust, such as anti-rotation guidance or synchronized dual-tool tasks. It yields 528 N both ways at 0.5 MPa. If you need less force, the 32 mm bore provides 345 N; for more power, the 50 mm bore offers 825 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet allows electronic or reed sensor mounting. At 220 mm stroke, side-load risks are moderate, so use external guide rails to prevent binding.
Quick checklist
The force is equal both ways because both faces have a 16 mm rod. It generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa in both extend and retract directions.
No, the air cushion only decelerates the piston near the stroke ends. To prevent drift on air loss, you must install an external rod lock or a pilot-operated check valve.
