Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X600
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X600 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 600mm 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-SAUD40X600
The B04-SAUD40X600 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD40X600, mechanically identical to the base model. Because a rod exits both ends, the output force is equal in both directions at 528 N each way at 0.5 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. It uses a 1/4" port and M12x1.25 rod thread.
A high-temperature Viton H seal option extends operation from 0 to 150 C. As this SKU lacks the -S magnet, it cannot accept magnetic switches. Mounting is compatible with AirTAC SC series FA flange and LB foot brackets.

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-SAUD40X600 Is Used
Excavator Door Control
Drives heavy cab doors on construction equipment with equal push and pull force, preventing twist during extended 600 mm travel.
Twin-Tool Actuation
Simultaneously operates dual clamping arms on heavy machinery fixtures using both rod ends for synchronized motion.
Mechanical Cam Tripping
Uses the protruding back rod as a mechanical cam to physically trip limit switches in rugged, high-vibration environments.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD40X600 the Right Cylinder?
Size this 40 mm bore against its neighbors: the 32 mm bore yields 345 N each way at 0.5 MPa, while the 50 mm bore provides 825 N. Choose this double-rod model when your application demands anti-rotation guidance, synchronized twin-tool driving, or a back rod to trip a mechanical switch. For the 600 mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads. Select FA or LB mounting brackets to match your frame. Note that without the -S magnet option, electronic position sensing is unavailable.
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-SAUD40X600 FAQ
Because this is a double-rod cylinder, the 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 never produces a larger single-rod push value. The 1/4" port and 21 mm adjustable cushions are fixed by the 40 mm bore.
The B04- prefix designates this as a construction-machinery dedicated variant of the SAUD40X600, sharing identical specifications. A plain cylinder does not hold a load on air loss; the cushion only decelerates near stroke end. For a held load, use an external rod lock or pilot-operated check valve.
