About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200S
The B04-SC100X200S is an AirTAC double-acting tie-rod cylinder built for construction machinery. The B04- prefix marks this as the construction-machinery dedicated variant of the SC100X200S, meaning it is mechanically identical to the standard model but designated for heavy-equipment builders. It features a 100mm bore and a 200mm stroke.
Delivering a robust 5497N of push force at 0.7 MPa, this unit is engineered for demanding work. The built-in S suffix magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for position detection. It uses a 25mm piston rod, PT1/2 port threads, and includes 29mm adjustable cushions to soften end-of-stroke impact.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200S Is Used
Excavator Actuation
Drives auxiliary covers or heavy flap mechanisms on earthmoving equipment where high 5497N push force is required.
Concrete Plant Gates
Operates aggregate batching gates and diverter valves in harsh concrete mixing environments requiring reliable linear motion.
Heavy Equipment Latches
Actuates robust locking pins and heavy-duty latches on cranes or loaders, utilizing the built-in magnet for position confirmation.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200S the Right Cylinder?
This 100mm bore provides 5497N push force at 0.7 MPa; stepping down to an 80mm bore drops the output to 3518N, while a 125mm bore increases it to 8590N. Choose this size when your heavy-equipment pneumatic circuit requires substantial push power within a compact tie-rod envelope.
For exact replacement matching, verify five points: 100mm bore, 200mm stroke, PT1/2 port thread, basic mounting (no bracket), and the built-in magnet (-S). Because the stroke is 200mm, manage potential side loads by using an external guide rail or a guided cylinder to prevent the 25mm rod bearing from bending under lateral stress.
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-SC100X200S FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated variant of the standard SC100X200S. It is mechanically identical to the base model, featuring the same 100mm bore, 200mm stroke, 25mm rod, and 5497N push force at 0.7 MPa.
No, the SC series is double-acting and does not lock or hold position without live air pressure. The 29mm adjustable cushions only decelerate the piston near stroke ends. To hold a vertical load safely, you must use an external mechanical lock, rod brake, or pilot-operated check valve.
