Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X250
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X250 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 250mm 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-SAUD80X250
The B04-SAUD80X250 is an AirTAC double-acting, double-rod profile cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the SAUD80X250, sharing identical mechanics. A rod exits both ends, meaning push and pull force is equal at 2268 N each way at 0.5 MPa (3175 N at 0.7 MPa, 4082 N at 0.9 MPa). It uses a 3/8" port and an M20x1.5 rod thread.
This extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. The dual rods provide anti-rotation guidance for heavy equipment. Without a -S suffix, this SKU cannot take a magnetic sensor.

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-SAUD80X250 Is Used
Excavator Linkage
Synchronizes dual tooling on heavy equipment arms with equal push and pull force.
Crusher Feed Gate
Provides anti-rotation guidance for heavy material flow control on job sites.
Paver Spreader
Drives two opposing forming tools simultaneously from one compact profile body.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD80X250 the Right Cylinder?
Choose this 80mm bore when you need 2268 N of equal bidirectional force. Step down to the 63mm bore for 1402 N, or up to the 100mm bore for 3681 N at 0.5 MPa. A double rod is the right call for construction machinery needing anti-rotation stability or twin tool mounting. Mounting is limited to Basic, FA, and LB types, compatible with the AirTAC SC series. At 250mm stroke, external side-load guides are recommended. Note this plain SKU lacks a magnet for CMSG/DMSG/EMSG 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-SAUD80X250 FAQ
The B04- prefix denotes the construction-machinery dedicated variant of the SAUD80X250 with 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.
No, the air cushion only decelerates near stroke end; it does not lock. On air loss the piston drifts. Use an external rod lock or pilot-operated check valve for holding. Also, without a -S suffix, this SKU cannot take a sensor.
