About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC63X225
The B04-SC63X225 is an AirTAC construction-machinery dedicated variant of the standard SC63X225 pneumatic cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base SC model, offering a 63mm bore and 225mm stroke.
This double-acting tie-rod cylinder generates 1559N of push force at 0.5 MPa and up to 2805N at 0.9 MPa. It features a 20mm piston rod, PT1/4 ports, and 28mm adjustable cushions to decelerate the piston at stroke ends. With a body length A of 153mm, the total extended length is 378mm.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC63X225 Is Used
Heavy Equipment Actuation
Drives secondary doors, covers, and positioning arms on excavators or loaders where a compact 63mm bore and 225mm stroke are required.
Concrete Plant Diverter
Shifts flow gates or diverter valves in aggregate and concrete handling systems, utilizing 2182N of thrust at 0.7 MPa.
Machinery Positioning
Actuates adjustable tracks, sprayer booms, or access panels on heavy agricultural and construction machinery.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC63X225 the Right Cylinder?
This 63mm bore provides a robust middle-ground force output. If your application requires less force, stepping down to a 50mm bore yields 982N at 0.5 MPa, while stepping up to an 80mm bore provides 2513N at 0.5 MPa. At a 225mm stroke, side loads can stress the rod bearing; use external guides or a guided cylinder to prevent bending.
When ordering a replacement, match these five points: 63mm bore, 225mm stroke, PT1/4 port thread, basic mounting (or the specific F-SC63 accessory), and no magnet. The SC is a tie-rod cylinder and is shorter than ISO 15552 units, so it is not a direct dimensional replacement for them.
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-SC63X225 FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SC63X225 cylinder, offering the same 63mm bore, 225mm stroke, and 2805N maximum thrust at 0.9 MPa.
No, the SC cylinder does not hold position without live air pressure. The adjustable 28mm cushion only decelerates the piston near the stroke end to soften impact. To hold a vertical load, you must use an external rod brake, mechanical lock, or pilot-operated check valve.
