The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X350 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 350mm 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-SAUD32X350 is AirTAC's construction-machinery dedicated variant of the SAUD32X350 double-acting, double-rod profile cylinder. The B04- prefix designates its industry application without altering the core mechanics. It features an extruded aluminum barrel and is notably shorter than an ISO 15552 cylinder of the same bore. A rod exits both ends, meaning both faces use the rod-side area and push and pull force are equal at 345 N each way at 0.5 MPa. The bore accepts a 1/8" port.
Because both ends carry a rod, it provides excellent anti-rotation guidance and can drive twin tooling simultaneously. Without a -S suffix, this SKU cannot take a magnetic switch. A Viton H seal option raises 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.
Drives dual forming tools on heavy equipment cabins with equal push and pull force, preventing twist during sheet metal bending.
Uses the twin-rod anti-rotation property to keep crawler track guides straight during field assembly without binding.
Cycles twin test probes simultaneously into hydraulic manifolds, using the compact profile to save space in tight test cells.
When sizing this 32 mm bore, compare its 345 N equal force against the 40 mm bore which yields 528 N each way at 0.5 MPa. A double-rod profile is the right call when your construction machinery needs anti-rotation stability, twin tooling, or a back-end cam. Mounting is limited to Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because the 350 mm stroke exceeds 300 mm, you must use external guides to prevent rod bending and side-load damage. Note that a plain cylinder does not hold load on air loss; use an external rod lock or pilot-operated check valve for secure holding.
Quick checklist
The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the SAUD32X350, mechanically identical to the base model. Force is equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The bore uses a 1/8" port.
No, this SKU lacks the -S suffix and cannot take a magnetic switch like the CMSG, DMSG, or EMSG sensors. If you need back-end sensing or switch tripping on the rear rod, select the -S magnet option instead.
