Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X200S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X200S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 200mm 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-SAUD80X200S
The B04-SAUD80X200S is an AirTAC construction-machinery dedicated double-rod profile cylinder. The B04- prefix marks it as a heavy-equipment variant, mechanically identical to the SAUD80X200S. It features an extruded aluminum barrel that is shorter than an ISO 15552 cylinder of the same 80mm bore. A rod exits both ends on one piston, so push and pull force are equal at 2268 N each way at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle robust flows.
Because both faces use the rod-side area, output is perfectly balanced. The back rod can carry a sensor cam or drive twin tools. This unit includes the -S magnet for CMSG, DMSG or EMSG switches. A Viton H seal option raises the operating ceiling to 150 C.

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-SAUD80X200S Is Used
Excavator Linkage
Synchronizes dual tooling on heavy equipment arms with equal push and pull force.
Material Transfer
Drives opposing clamps from a single body to grip and move construction materials.
Back-End Sensing
Uses the protruding rear rod to trip a CMSG switch in tight machinery bays.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X200S the Right Cylinder?
Size both ways: the 63mm bore yields 1402 N, while the 100mm bore provides 3681 N at 0.5 MPa. Choose this 80mm double-rod when you need anti-rotation guidance, twin tooling, or back-end sensing on construction equipment. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. The 200mm stroke is under the 300mm side-load threshold, but always use external guides for heavy off-center loads. The -S magnet enables position 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-SAUD80X200S FAQ
The B04- prefix marks this as a construction-machinery dedicated variant of the SAUD80X200S, with 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 inch port.
No, a plain double-rod cylinder drifts without live air. The adjustable 28mm cushions only decelerate near stroke end. For a locked load, install an external rod lock or pilot-operated check valve.
