About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X225
The B04-SC100X225 is AirTAC's construction-machinery dedicated variant of the standard SC100X225 single-rod, double-acting tie-rod cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base SC model, offering a 100mm bore and a 225mm stroke. Because 225mm is not a standard catalog stroke, it is produced as a made-to-order length.
This cylinder delivers a push force of 3927N at 0.5MPa and reaches 7068N at its 0.9MPa maximum operating pressure. It features a 25mm piston rod, PT1/2 ports, and 29mm adjustable cushions to decelerate the piston at stroke ends. The overall extended length is approximately 413mm (188mm body length A plus the 225mm stroke).

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X225 Is Used
Excavator Accessory Actuation
Drives secondary heavy-equipment attachments on construction machinery where a robust 3927N push force at 0.5MPa is required to move linkage.
Heavy Press Ejection
Ejects dense materials or formed components from machinery beds, utilizing the 225mm stroke to fully clear the work area.
Equipment Gate Control
Opens and closes heavy sorting or holding gates on mobile construction equipment, relying on adjustable cushions to soften end-of-stroke impact.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X225 the Right Cylinder?
This 100mm bore provides 3927N of push force at 0.5MPa. If your construction machinery needs less force, stepping down to an 80mm bore yields 2513N; if you require more, a 125mm bore offers 6136N. When replacing this unit, match the 100mm bore, 225mm stroke, PT1/2 port thread, basic mounting, and non-magnet configuration exactly.
Because the 225mm stroke exceeds 300mm? No, at 225mm the stroke is moderate, but any side load on the extended 25mm rod should still be minimized. For heavy off-road pivoting loads, use external guides or a guided cylinder to prevent rod bearing wear.
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-SC100X225 FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated variant of the SC100X225 cylinder. It is mechanically identical to the standard SC100X225, offering the same 100mm bore, 225mm stroke, and 7068N thrust at 0.9MPa.
No, 225mm is a non-standard stroke. The nearest standard strokes are 200mm and 250mm. AirTAC manufactures this as a made-to-order cylinder to meet specific machinery dimensions.
