Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X150S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X150S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 150mm 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-SAUD40X150S
The B04-SAUD40X150S is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD40X150S, mechanically identical to the base model. A rod exits both ends, meaning push and pull forces are equal at 528 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" port and an M12x1.25 rod thread.
Because both faces use the rod-side area, output is perfectly balanced. The -S suffix provides a built-in piston magnet for CMSG, DMSG or EMSG switches. For high-temperature environments, a Viton H seal option extends operation to 150 C.

Specifications follow the official AirTAC SAU series datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G (BSPP). A high-temperature seal (0-150 °C) is available.
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-SAUD40X150S Is Used
Excavator Panel Pusher
Synchronised dual rods drive cab panels straight without twisting in heavy-equipment assembly.
Loader Transfer Gate
Equal push and pull forces operate a reversing diverter gate on construction material lines.
Crane Component Gauge
The rear rod carries a sensor cam to verify clamp position on heavy-machinery test rigs.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X150S the Right Cylinder?
Size both ways: the 32 mm bore yields 345 N, while the 63 mm bore provides 1402 N (both at 0.5 MPa). Choose this 40 mm double-rod unit when you need anti-rotation guidance, twin tooling, or a back-end sensor cam. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 150 mm stroke, external side-load guides are recommended to prevent premature seal wear. 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-SAUD40X150S FAQ
The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD40X150S, 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" port.
No, a plain cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near stroke ends. To hold a vertical load securely, fit an external rod lock or pilot-operated check valve.
