About the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X500S
The B04-SAUD80X500S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD80X500S, mechanically identical to the base unit. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 2268 N each way at 0.5 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This 80mm bore model features a 25mm rod, M20x1.5 rod-end thread, and a 3/8" port. With a 500mm stroke, external guides are recommended to prevent rod bending under side loads. The -S suffix provides a built-in piston magnet for CMSG, DMSG, or EMSG switches.

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-SAUD80X500S Is Used
Excavator Panel Pusher
Drives heavy cab panels on earthmoving equipment with equal push and pull force, preventing twist during synchronized forming operations.
Crusher Feed Diverter
Uses the twin-rod design to flip aggregate routing gates on construction sites, ensuring stable non-rotating movement under heavy vibration.
Concrete Mold Release
Mounts a switch cam on the back rod to trip an electronic sensor, timing the precise release of precast concrete forms.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X500S the Right Cylinder?
When sizing this double-rod unit, the 80mm bore delivers 2268 N equal force both ways. If less force is needed, the 63mm bore provides 1402 N; if more is required, the 100mm bore offers 3681 N. Choose this twin-rod architecture for anti-rotation guidance, driving two tools at once, or mounting a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the stroke is 500mm, always use external guides to manage side loads and prevent rod bending. The -S magnet supports reed or electronic sensing.
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-SAUD80X500S FAQ
The B04- prefix denotes the construction-machinery dedicated variant of the SAUD80X500S, sharing identical specs. Force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It uses a 3/8" port.
No, a plain cylinder drifts without live air. The adjustable 28mm cushions only decelerate near stroke end. For a held load, install an external rod lock or pilot-operated check valve.
