Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD50X800
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD50X800 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 800mm 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-SAUD50X800
The B04-SAUD50X800 is an AirTAC construction-machinery dedicated double-rod profile cylinder. The B04- prefix marks it as a heavy-equipment variant of the SAUD50X800, mechanically identical to the base model. It features an extruded aluminum barrel that is shorter than an ISO 15552 cylinder of the same bore. A rod protrudes from both ends, yielding equal push and pull force of 825 N each way at 0.5 MPa. The 1/4" port and M16x1.5 rod thread handle robust pneumatic flows.
Because both faces lose rod area, output is balanced for non-rotating or twin-tool duty. The back rod can drive a second mechanism. This SKU lacks a magnet, so it cannot take a magnetic switch. A plain cylinder drifts on air loss; the cushions only decelerate, so use an external rod lock for held loads.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | — |
| Max (@1.0 MPa) | 168 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-SAUD50X800 Is Used
Excavator Panel Pusher
Drives cabin panels on heavy equipment using equal bidirectional force to prevent twist during extension.
Loader Transfer Gate
Synchronizes a dual-tool sorting gate on construction material lines, using the back rod for a cam.
Crusher Feed Diverter
Handles raw aggregate routing with balanced push and pull forces in harsh machinery environments.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD50X800 the Right Cylinder?
Size both ways: the 40 mm bore gives 528 N each way, while the 63 mm bore yields 1402 N. This 50 mm bore provides 825 N at 0.5 MPa. Choose a double rod for anti-rotation guidance, twin tooling, or back-end cam duty. Mounting fits AirTAC SC series FA flange and LB foot brackets. At 800 mm stroke, external guides are mandatory to prevent rod bending under side loads. Without a -S suffix, this SKU cannot accept CMSG or DMSG sensors.
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-SAUD50X800 FAQ
Force is equal both ways: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The B04- prefix indicates the construction-machinery dedicated variant of the SAUD50X800, sharing identical specs.
No. This SKU lacks the -S magnet option, so it cannot trigger CMSG or DMSG switches. You would need the -S version for position sensing.
