Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X175
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X175 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 175mm stroke, 1/4" 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-SAUD40X175
The B04-SAUD40X175 is an AirTAC construction-machinery dedicated double-rod profile cylinder. The B04- prefix marks it as a heavy-equipment variant, mechanically identical to the standard SAUD40X175. It features a 40 mm bore, 175 mm stroke, and a 1/4 inch port. Because a rod exits both ends, the output force is equal in both directions, delivering 528 N each way at 0.5 MPa.
This extruded aluminum body is shorter than a standard ISO 15552 cylinder of the same bore. The twin rods provide anti-rotation guidance for synchronized tool driving. This SKU lacks a magnet and cannot take a sensor. The Viton H seal option raises the operating temperature to 0-150 C.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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-SAUD40X175 Is Used
Excavator Valve Tripping
Uses the twin-rod anti-rotation feature to actuate heavy-equipment pilot valves reliably without mechanical twist.
Crane Load Positioning
Drives dual synchronization tools from both rod ends to align structural components on construction sites.
Concrete Dispenser Gates
Applies equal 528 N force in both directions to open and close heavy aggregate gates on mixing machinery.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X175 the Right Cylinder?
Select this 40 mm bore model when your mechanism requires equal push and pull forces alongside anti-twist stability. If you need less force, the 32 mm bore yields 345 N both ways at 0.5 MPa. If your application demands more power, step up to the 50 mm bore which provides 825 N each way. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. Since this 175 mm stroke is under 300 mm, side-load stress is minimal, but external guides are still recommended for rigid loads. Note that this non-magnet SKU cannot host CMSG or DMSG switches.
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-SAUD40X175 FAQ
The B04- prefix denotes the construction-machinery dedicated variant of the SAUD40X175, sharing identical specs. Force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It uses a 1/4 inch port and M12x1.25 rod thread.
No. A plain double-rod cylinder drifts on air loss and the adjustable cushion only decelerates near stroke end. For vertical load holding on machinery, install an external rod lock or pilot-operated check valve.
