About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X225S
The B04-SC100X225S is an AirTAC double-acting tie-rod pneumatic cylinder engineered for heavy-duty cycles. The B04- prefix designates this as a construction-machinery dedicated variant, mechanically identical to the standard SC100X225S. It features a 100mm bore and a 225mm stroke, generating 5497N of push force at 0.7 MPa.
Equipped with a built-in magnet (S suffix), this unit allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for precise end-of-stroke detection. The 25mm piston rod and 29mm adjustable cushions absorb impact at stroke endpoints, while the 188mm body length A yields a total extended length of 413mm.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X225S Is Used
Excavator Door Actuation
Drives heavy cab doors or access panels on earthmoving equipment, utilizing the magnetic piston to confirm locked open and closed positions for operator safety.
Concrete Dispenser Gate
Opens and closes abrasive material discharge gates on batching systems, relying on the 5497N thrust at 0.7 MPa to move heavy aggregate loads reliably.
Heavy Equipment Lifting Arm
Positions secondary lifting or stabilizing arms on mobile cranes, where the adjustable cushions decelerate the 25mm rod smoothly under high inertial loads.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X225S the Right Cylinder?
This 100mm bore provides 3927N push force at 0.5 MPa. If your application requires less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa, while moving up to a 125mm bore provides 6136N. For this 225mm stroke, monitor side loads closely; long unsupported rods bend under lateral stress, so utilize an external guide rail or a guided cylinder to prevent rod-bearing damage.
When specifying a replacement, match these five attributes exactly: 100mm bore, 225mm stroke, PT1/2 port thread, basic mounting style, and the built-in magnet (-S). Note that the SC is a tie-rod cylinder and is shorter than ISO 15552 profile cylinders, meaning it is not a drop-in 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-SC100X225S FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated cylinder. It is mechanically and dimensionally identical to the standard SC100X225S, featuring the same 100mm bore, 225mm stroke, PT1/2 port, and built-in magnet, simply designated for heavy-equipment manufacturing.
No, the SC cylinder does not hold its position when air pressure is lost or exhausted. The adjustable cushions only decelerate the piston near the stroke end to soften impact; they do not act as a brake. A mechanical lock or external pilot-operated check valve is required to hold vertical loads safely.
