Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X250
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X250 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 250mm 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-SAUD100X250
The B04-SAUD100X250 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD100X250, sharing the exact same physical specs. Because a rod exits both ends, the output force is equal in both directions, delivering 3681 N each way at 0.5 MPa. The extruded aluminum profile keeps the unit shorter than an ISO 15552 cylinder of the same bore.
This model features a 1/2 inch port, a 25 mm rod with an M20x1.5 thread, and adjustable air cushions at both ends. Without the -S suffix, this SKU cannot accept magnetic sensors.

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-SAUD100X250 Is Used
Excavator Boom Actuation
Provides synchronized, non-rotating push and pull force for heavy equipment boom mechanisms where equal bidirectional power is required.
Crusher Tooling Drive
Drives twin jaw or crushing tools from both rod ends simultaneously, ensuring parallel material processing in harsh construction environments.
Paver Synchronized Gate
Operates dual gating mechanisms on asphalt pavers using the back rod for mechanical cam actuation without electronic sensors.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X250 the Right Cylinder?
Select this 100 mm bore when your application requires 3681 N of equal push and pull force at 0.5 MPa. If you need less force, step down to the 80 mm bore offering 2268 N both ways. If you need more, note that 100 mm is the largest available SAUD size. The double-rod design is the right call when you need anti-rotation guidance, twin tooling, or a back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot options, matching the AirTAC SC series. For this 250 mm stroke, ensure external guides support any side loads 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-SAUD100X250 FAQ
The 100 mm bore features a 1/2 inch port and a 25 mm rod. Because it is a double-rod cylinder, 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 denotes the construction-machinery dedicated variant, mechanically identical to the SAUD100X250.
This SKU lacks the -S magnet option, so it cannot accept magnetic sensors. Additionally, a plain cylinder does not hold a load on air loss; the air cushion only decelerates near stroke end. For vertical load holding, you must use an external rod lock or a pilot-operated check valve.
