Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X800S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X800S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 800mm 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-SAUD63X800S
The B04-SAUD63X800S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD63X800S, mechanically identical to the base unit. Because a rod exits both ends, the output is equal in both directions at 1402 N each way at 0.5 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, M16x1.5 rod thread, and an integrated magnet for CMSG/DMSG/EMSG switches.
A high-temperature Viton H seal option extends operation to 150 C. Note that a plain cylinder does not hold load without live air; the cushions only decelerate near stroke end, so use an external rod lock for suspended loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |
| Max (@1.0 MPa) | 286 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-SAUD63X800S Is Used
Excavator Panel Indexing
Drives synchronized heavy-equipment panels from both ends to prevent twisting during long 800 mm travel on construction machinery.
Twin-Tool Actuation
Carries a secondary tool or cam on the back rod for sequential operations in harsh heavy-equipment assembly lines.
Material Transfer Gates
Pushes and pulls aggregate routing gates with equal 1402 N force, using the compact profile to fit tight machinery frames.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X800S the Right Cylinder?
When sizing this 63 mm bore, the 50 mm neighbor yields 825 N, while the 80 mm bore provides 2268 N, both equal in both directions at 0.5 MPa. Choose a double-rod configuration when you need anti-rotation guidance, twin tooling, or a back-end sensor cam. Mounting is limited to Basic, FA, and LB brackets compatible with the AirTAC SC series. The -S suffix enables CMSG/DMSG/EMSG sensors. Because the 800 mm stroke exceeds 300 mm, external guides are required to prevent rod bending and manage side loads.
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-SAUD63X800S FAQ
The B04- prefix designates this as the construction-machinery dedicated variant of the SAUD63X800S, sharing identical specs. The 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 double-rod cylinder drifts without live air; the adjustable cushions only decelerate near the stroke end. For suspended loads, install an external rod lock or pilot-operated check valve.
