The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X175S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 175mm stroke, 1/8" 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 B04-SAUD32X175S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant, mechanically identical to the SAUD32X175S. A rod exits both ends, meaning both faces use the rod-side area to deliver an equal force of 345 N each way at 0.5 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. It features a 1/8" port and an M10x1.25 rod thread.
Because the second rod prevents piston twist, this unit provides excellent anti-rotation guidance for twin-tool or synchronized tasks. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. A Viton H seal option can raise the operating temperature to 0-150 C.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
Equal push and pull force drives and retracts a panel alignment tool on heavy equipment assembly lines without rotational drift.
The twin-rod geometry provides stable anti-twist guidance for positioning wear plates inside construction jaw crushers.
The protruding back rod carries a sensor cam, allowing CMSG switches to verify full travel while cycling hydraulic valve cartridges.
When sizing this double-rod unit, compare both ways: stepping up to the 40 mm bore yields 528 N, while stepping down is unavailable as 32 mm is the smallest. Choose this 32 mm bore when you need strict anti-rotation, twin tooling, or a back-end sensor cam. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. The -S magnet enables position sensing. At 175 mm stroke, side loads are moderate, but external guide rails are recommended for heavy off-center loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates.
Quick checklist
The B04- prefix denotes the construction-machinery dedicated variant of the SAUD32X175S, sharing identical specs. Force is equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. It uses a 1/8" port.
The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors. The double-rod design ensures equal force both ways, prevents piston rotation, and offers a back rod for mounting switch cams.
