Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X1000S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X1000S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 1000mm 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.

About the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X1000S
The B04-SAUD80X1000S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD80X1000S, mechanically identical to the base model. A rod exits both ends on one piston, meaning both faces use the rod-side area. Output force is equal in both directions: 2268 N each way at 0.5 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This 80mm bore unit features a 3/8" port and a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. The dual rods provide anti-rotation guidance and allow a sensor cam to ride on the back rod. Viton H seals can raise the operating temperature to 150 C.

Specifications follow the official AirTAC SAU series datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G (BSPP). A high-temperature seal (0-150 °C) is available.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
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.

Where the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X1000S Is Used
Excavator Panel Indexing
Drives heavy cab panels on earthmoving equipment using equal push and pull force, with the back rod tripping a limit switch.
Crane Block Alignment
Synchronizes two lifting tools on construction cranes, relying on the twin rods to prevent twist during load transfers.
Concrete Pump Gate
Shifts diverter gates on concrete machinery, using the compact profile to fit tight chassis spaces while handling high forces.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X1000S the Right Cylinder?
Size both ways: the 63mm bore yields 1402 N at 0.5 MPa, while the 100mm bore provides 3681 N. Choose this 80mm double-rod cylinder when your application needs anti-rotation stability, twin tooling, or back-end sensing. Mounting is limited to Basic, FA, and LB styles, sharing compatibility with the AirTAC SC series. Because the stroke is 1000mm, external guides are recommended to prevent rod bending under side loads. The -S magnet enables position sensing. Note that a plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for load holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X1000S FAQ
This 80mm bore cylinder has a 3/8" port and a 25mm rod. Because it is a double-rod design, the force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The B04- prefix simply denotes the construction-machinery dedicated variant.
The dual rods prevent rotation and allow a sensor cam on the back rod. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The air cushion only decelerates near stroke end; it does not hold the load without live air.
