About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X350S
The B04-SC100X350S is an AirTAC double-acting tie-rod cylinder engineered for construction machinery. The B04- prefix designates this as the construction-machinery dedicated variant of the SC100X350S, meaning it is mechanically identical to the standard model but tailored for heavy-equipment builders. It features a 100mm bore and a 350mm stroke, generating a push force of 3927 N at 0.5 MPa and a maximum push of 7068 N at 0.9 MPa.
This unit includes a built-in magnet for position sensing via CMSG, DMSG, or EMSG sensors. It uses a 25mm piston rod, a PT1/2 port, and has an adjustable cushion length of 29mm to decelerate the piston at stroke ends. With a body length A of 188mm, the total extended length is approximately 538mm.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X350S Is Used
Excavator Actuation
Drives auxiliary covers or maintenance panels on heavy excavators, utilizing its 7068 N thrust at 0.9 MPa to move heavy components reliably.
Concrete Dispenser
Actuates diverter gates on concrete mixing trucks, where the built-in magnet confirms gate position to the machine's control system.
Heavy Equipment Lifting
Provides the linear push required to raise and lower heavy structural arms on cranes or loaders, handling substantial loads with stable air pressure.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X350S the Right Cylinder?
This 100mm bore provides 3927 N of push force at 0.5 MPa; if your application requires less force, stepping down to an 80mm bore yields 2513 N, while moving up to a 125mm bore offers 6136 N. For replacement matching, ensure the new cylinder shares the exact 100mm bore, 350mm stroke, PT1/2 port thread, basic mounting style, and the -S magnet option.
Because this model has a 350mm stroke, the extended 25mm rod is susceptible to bending under side loads. For heavy construction equipment applications, use an external guide rail or a guided cylinder to prevent rod-bearing damage and premature 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-SC100X350S FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated cylinder. It is mechanically identical to the standard SC100X350S, offering the same 100mm bore, 350mm stroke, 7068 N thrust at 0.9 MPa, and built-in magnet, but is designated for heavy-equipment builders.
No, the SC cylinder is double-acting and does not hold position without live air pressure. The adjustable 29mm cushion only decelerates the piston at the end of the stroke; it does not act as a brake. A mechanical lock or external pilot-operated check valve is required to hold vertical loads safely.
