Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X800S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X800S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 800mm stroke, 1/2" 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-SAUD100X800S
The B04-SAUD100X800S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD100X800S, mechanically identical to the base model. Its extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. A rod protrudes from both ends, yielding equal push and pull force of 3681 N each way at 0.5 MPa. The 1/2 inch port and M20x1.5 rod thread handle heavy flows.
Because both faces use the rod-side area, output is perfectly symmetrical. The -S suffix provides a built-in magnet for CMSG, DMSG or EMSG switches. For this 800 mm stroke, external guides are essential to prevent rod bending under side loads. 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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-SAUD100X800S Is Used
Excavator Linkage
Synchronizes dual tooling on heavy equipment with equal push and pull force.
Loader Actuation
Provides non-rotating linear motion for construction machinery control surfaces.
Material Transfer
Drives opposing clamps simultaneously using both extending rod ends.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X800S the Right Cylinder?
Size both ways: the 80 mm bore yields 2268 N each way at 0.5 MPa, while this 100 mm bore provides 3681 N. Choose a double rod when you need anti-rotation guidance, twin tooling, or a back-end sensor cam. Mounting is limited to Basic, FA and LB styles, matching the AirTAC SC series. The -S magnet enables position sensing. For the 800 mm stroke, always use external guides to absorb side loads and prevent rod bending.
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-SAUD100X800S FAQ
The B04- prefix marks this as the construction-machinery dedicated variant of SAUD100X800S, with identical specs. Force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It uses a 1/2 inch port.
No. The adjustable 29 mm air cushions only decelerate the piston near stroke ends. A plain cylinder drifts without live air. For load holding, install an external rod lock or pilot-operated check valve.
