Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X50S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X50S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 50mm 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-SAUD100X50S
The B04-SAUD100X50S is AirTAC's construction-machinery dedicated variant of the SAUD100X50S profile-type double-rod cylinder. The B04- prefix designates its heavy-equipment industry alignment without altering the core mechanics. Because a rod exits both ends, the push and pull output is identical at 3681 N each way at 0.5 MPa. The extruded aluminum profile is shorter than a standard ISO 15552 cylinder of the same bore.
This 100mm bore unit uses a 1/2 inch port and a M20x1.5 rod thread. The built-in magnet (-S) supports CMSG, DMSG, or EMSG switches for position sensing. For high-temperature environments, Viton H seals extend the operating range up to 150 C.

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-SAUD100X50S Is Used
Excavator Valve Actuation
Drives twin spools simultaneously on heavy equipment with equal push and pull force, ensuring synchronized hydraulic routing.
Crane Load Stabilizer
Uses the double-rod geometry to prevent torsional twist during heavy lift compensation on construction machinery.
Concrete Pump Reset
Employs the back rod to trigger a proximity switch, confirming full retraction in dusty aggregate environments.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X50S the Right Cylinder?
Select this 100mm bore model when your application demands equal force in both directions, anti-rotation stability, or a back rod to trip a switch. It yields 3681 N both ways at 0.5 MPa. If you need less power, the 80mm bore provides 2268 N. If you need more, verify the 100mm is your largest required option. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet allows direct sensor mounting. For this 50mm stroke, side-load is minimal, but any stroke over 300mm requires external guide rails to prevent binding.
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-SAUD100X50S FAQ
The bore is 100mm with a 1/2 inch port. Because it is a double-rod cylinder, the force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The B04- prefix simply marks it as the construction-machinery dedicated variant of the SAUD100X50S.
No, a plain double-rod cylinder drifts without live air. The adjustable 29mm cushions only decelerate the piston near stroke end. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
