The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X500 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 500mm stroke, 3/8" 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-SAUD63X500 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD63X500, mechanically identical to the base model. Because a rod exits both ends, the push and pull output is equal at 1402 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than an ISO 15552 cylinder of the same bore.
You can mount it via Basic, FA flange, or LB foot brackets matching the AirTAC SC series. This SKU lacks a magnet, so it cannot take CMSG or DMSG sensors. For high-heat duties, Viton H seals raise the operating limit to 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 cabin panels on heavy equipment with equal push and pull force, using the twin rods to prevent twist during forming.
Balances dual tooling attachments on construction machinery, keeping strokes aligned without relying on external rails.
Uses the protruding back rod to mechanically trip a limit switch on a heavy-equipment rig, since this unit lacks an internal magnet.
Size both ways: the 50 mm bore yields 825 N, while the 80 mm bore yields 2268 N, both equal in both directions. Choose this 63 mm double-rod unit when you need anti-rotation guidance, twin tooling, or a back-end cam. It uses FA or LB mounting. Since this is a 500 mm stroke, external guides are recommended to prevent rod bending under side loads. Note that this SKU has no -S magnet and cannot host sensors.
Quick checklist
The B04- prefix designates the construction-machinery dedicated variant of the SAUD63X500, sharing the exact same specs. Force is equal both ways: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It uses a 3/8" port.
No, a plain cylinder drifts on air loss; the air cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve to hold loads. Also, this SKU lacks the -S magnet, so it cannot host magnetic sensors.
