About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150S
The AirTAC B04-SC100X150S is a double-acting tie-rod cylinder engineered for heavy-equipment builders. The B04- prefix designates this as a construction-machinery dedicated variant of the SC100X150S, meaning it is mechanically identical to the standard model but tailored for OEMs in the heavy-machinery sector. It features a 100mm bore and a 150mm stroke.
Delivering a robust 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, this unit handles substantial loads. The S suffix indicates a built-in magnet for mounting CMSG, DMSG, or EMSG sensors along the 188 mm body. Adjustable cushions provide 29 mm of deceleration at stroke ends to absorb impact energy.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150S Is Used
Excavator Actuation
Drives auxiliary covers and heavy flap mechanisms on earthmoving equipment where the B04 construction-machinery designation is essential.
Heavy Press Ejection
Provides the 7068 N force at 0.9 MPa needed to eject dense formed parts from large industrial presses.
Material Routing Gates
Shifts heavy diverter gates on aggregate and concrete batching conveyors with reliable double-acting power.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150S the Right Cylinder?
This 100mm bore provides 3927 N at 0.5 MPa; stepping down to an 80mm bore yields 2513 N, while moving up to a 125mm bore offers 6136 N. For replacements, match the 100mm bore, 150mm stroke, PT1/2 port thread, basic mounting, and the -S magnet option exactly.
At a 150mm stroke, side loads are moderate, but always ensure the load is guided to prevent rod-bearing wear. For longer extensions, an external guide rail or a guided cylinder is recommended to prevent the 25mm rod 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-SC100X150S FAQ
The B04- prefix indicates this is a construction-machinery dedicated variant of the SC100X150S. It is mechanically identical to the standard SC100X150S, offering the same 100mm bore, 150mm stroke, and 3927 N force at 0.5 MPa.
No, the SC series does not lock or hold position when air pressure is lost. The adjustable cushion only decelerates the piston near the stroke end. To hold a vertical load safely, you must use an external mechanical lock or a pilot-operated check valve.
