About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X1000
The B04-SC100X1000 is an AirTAC construction-machinery dedicated double-acting tie-rod cylinder. The B04- prefix designates it as the heavy-equipment variant of the standard SC100X1000, sharing identical mechanical specifications. It delivers 3927N of push force at 0.5MPa and up to 7068N at 0.9MPa, making it suited for heavy industrial actuation.
Featuring a 1000mm stroke and a 25mm piston rod, this unit has a body length A of 188mm and 29mm adjustable cushions at both ends. It operates on filtered air between 0.15 and 1.0MPa, with a speed range of 30-800mm/s.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X1000 Is Used
Excavator Arm Actuation
Drives auxiliary pivoting mechanisms on heavy construction equipment where a long 1000mm extension and 7068N force at 0.9MPa are required.
Heavy Press Ejection
Ejects large formed parts from industrial presses, utilizing the 29mm adjustable cushions to decelerate the heavy 25mm rod at stroke end.
Bulk Material Gate
Opens and closes heavy aggregate hopper gates on construction sites, relying on 3927N of push force at 0.5MPa to move loaded doors.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X1000 the Right Cylinder?
This 100mm bore provides 3927N push force at 0.5MPa; if your application requires less force, the 80mm bore offers 2513N, while the 125mm bore steps up to 6136N. For a 1000mm stroke, the unsupported 25mm rod is highly susceptible to bending under side loads—use an external guide rail or a guided cylinder to prevent rod-bearing damage.
When specifying a replacement, match the 100mm bore, 1000mm stroke, PT1/2 port thread, basic mounting, and confirm whether a built-in magnet (-S) is required for sensor tracking.
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-SC100X1000 FAQ
The B04- prefix indicates this is a construction-machinery dedicated variant of the SC100X1000. It is mechanically identical to the standard model, offering the same 7068N force at 0.9MPa, 25mm rod, and PT1/2 port, simply designated for heavy-equipment builders.
No, the SC series is double-acting and does not lock or hold position when air pressure is lost. The adjustable cushions only decelerate the piston near stroke ends. To hold a vertical load safely, you must use an external rod brake or pilot-operated check valve.
