About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X225S
The B04-SC32X225S is an AirTAC double-acting tie-rod pneumatic cylinder engineered for construction machinery. The B04- prefix designates this as a construction-equipment dedicated variant of the standard SC32X225S, meaning it shares the exact same physical specs, including a 32mm bore, 225mm stroke, and a 12mm piston rod.
Operating at 0.5 MPa, it provides 402N of push thrust and 345N of pull thrust, peaking at 724N when supplied with 0.9 MPa. The S suffix indicates a built-in magnet for position sensing, while adjustable cushions at both ends provide 21mm of deceleration to protect the end caps.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X225S Is Used
Excavator Accessory Actuation
Drives secondary attachments and compact linkage mechanisms on earthmoving equipment where a 724N peak force is adequate.
Concrete Pump Valving
Shifts small diverter valves or flow controls in concrete pumping systems, utilizing the built-in magnet for stroke confirmation.
Crane Outrigger Locking
Operates mechanical locking pins or indicator arms on mobile crane outriggers, relying on adjustable cushions to soften impact.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X225S the Right Cylinder?
This 32mm bore fits compact actuation needs on heavy equipment where 402N at 0.5 MPa is sufficient. If your application demands greater push force, stepping up to a 40mm bore yields 628N at 0.5 MPa. Conversely, smaller bores should only be considered if the load is very light. To replace this unit, match the 32mm bore, 225mm stroke, PT1/8 port thread, basic mounting style, and the magnetic piston option.
Because the 225mm stroke is substantial for a 12mm rod, side loads can cause rod-bearing bending and premature wear. For heavy construction environments, use an external guide rail or a guided cylinder to support the load and prevent rod deflection.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X225S FAQ
The B04- prefix indicates that this is an AirTAC construction-machinery dedicated variant of the SC32X225S cylinder. It is mechanically identical to the standard model, offering the same 32mm bore, 225mm stroke, and 724N maximum thrust at 0.9 MPa.
No, the SC series is double-acting and cannot hold position without live air pressure. If your construction application must hold a vertical load during pressure loss, you must install an external rod brake or a pilot-operated check valve.
