Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X225
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X225 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 225mm stroke, 1/8" 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-SAUD32X225
The B04-SAUD32X225 is an AirTAC construction-machinery dedicated double-rod profile cylinder. The B04- prefix marks it as the heavy-equipment variant of the SAUD32X225, sharing identical mechanics. It yields 345 N of output force each way at 0.5 MPa through its 1/8" port. The twin-rod architecture prevents piston rotation, making it ideal for synchronized tooling. Its extruded aluminum body is shorter than an ISO 15552 unit of the same bore.
Because both faces use the rod-side area, push and pull forces match exactly. This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments, Viton H seals raise the operating limit to 150 C.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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-SAUD32X225 Is Used
Excavator Valve Bank
Drives a synchronized twin-push mechanism on a hydraulic valve bank assembly jig, using equal force both ways to seat components without twist.
Crane Counterweight
Indexes heavy-equipment counterweight pins on the production line, relying on the anti-rotation double rod to keep the alignment fixture steady.
Loader Arm Welding
Clamps loader arm brackets during robotic welding, using the compact profile barrel to fit within tight machinery frames.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD32X225 the Right Cylinder?
Select this 32 mm bore if you need 345 N of equal bidirectional force. Sizing up to the 40 mm bore provides 528 N each way, while stepping down is not an option as 32 mm is the smallest available. A double rod is the right call when your setup demands anti-rotation guidance or twin-tool driving. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 225 mm stroke, external load guides are recommended to prevent side-load wear. Remember this non-magnetic SKU cannot host a sensor switch.
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-SAUD32X225 FAQ
The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the SAUD32X225, mechanically identical to the base model. Force is equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. It uses a 1/8" port and M10x1.25 rod thread.
No to both. The air cushion only decelerates near stroke end; without live air the piston drifts, so use an external rod lock or pilot-operated check valve for holding. Also, this SKU lacks a magnet and cannot take CMSG or DMSG sensors.
