Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X350
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X350 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 350mm stroke, 3/8" 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-SAUD80X350
The B04-SAUD80X350 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD80X350, mechanically identical to the base model. Because a rod exits both ends, the output force is equal in both directions, delivering 2268 N each way at 0.5 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, M20x1.5 rod thread, and adjustable air cushions at both ends.
The dual rods provide anti-rotation guidance and can drive twin tooling simultaneously. This non-magnet SKU cannot accept a sensor switch. Note that a plain cylinder does not hold load without live air; the cushions only decelerate, so use an external rod lock for suspended loads. At 350 mm stroke, external guides are recommended to prevent rod bending under side loads.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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-SAUD80X350 Is Used
Excavator Actuation
Drives synchronized gripper arms on heavy equipment with equal push and pull force, preventing twist during debris handling.
Crane Load Alignment
Uses dual rods to provide non-rotating guidance for positioning heavy structural components on construction sites.
Twin Tool Deployment
Powers dual cutting or pressing heads simultaneously from opposite rod ends, ensuring balanced force for machinery assembly.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X350 the Right Cylinder?
When sizing this 80 mm bore, stepping down to the 63 mm bore yields 1402 N each way at 0.5 MPa, while stepping up to the 100 mm bore provides 3681 N. A double-rod design is the right call when your application demands strict anti-rotation, synchronized twin tooling, or a back rod to trip a switch. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot support CMSG or DMSG sensors. With a 350 mm stroke, always use external guides to manage side loads and prevent rod bending. For load holding on air loss, add a pilot-operated check valve.
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-SAUD80X350 FAQ
The B04- prefix indicates this is the construction-machinery dedicated variant of the SAUD80X350, sharing identical specs. Force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It uses a 3/8" port.
This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. Additionally, it does not hold loads without live air; the cushions only decelerate. For suspended loads, install an external rod lock or pilot-operated check valve.
