About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200STC
The B04-SC100X200STC is AirTAC's construction-machinery dedicated variant of the SC100X200STC pneumatic cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the standard SC line, delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa.
This double-acting tie-rod cylinder features a 100 mm bore and 200 mm stroke. It includes a built-in magnet for position sensing and a TC centre-trunnion mount for pivoting loads. The unit uses a 25 mm rod, PT1/2 ports, and has a body length A of 188 mm.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200STC Is Used
Excavator Actuation
Drives auxiliary heavy-equipment panels and covers on construction machinery where high force and pivot mounting are required.
Heavy Stamping
Provides 7068 N of thrust at 0.9 MPa for pressing and clamping heavy structural components in fabrication jigs.
Material Diversion
Pivots heavy diverter gates on aggregate or bulk material conveyors using the TC centre-trunnion mount.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200STC the Right Cylinder?
This 100 mm bore provides massive thrust; step down to an 80 mm bore (2513 N at 0.5 MPa) if your application requires less force to save space and air consumption. For heavier loads, verify if a larger bore is necessary. Replacement matches must align exactly on bore, stroke, PT thread, TC mounting bracket (F-SC100TC), and the -S magnet option.
At a 200 mm stroke, side loads can stress the rod bearing. If the mechanism cannot maintain pure linear alignment, use an external guide rail or a guided cylinder to prevent premature seal wear and rod bending.
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-SC100X200STC FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. The B04-SC100X200STC is mechanically and dimensionally identical to the standard SC100X200STC, offering the same 7068 N thrust at 0.9 MPa and 25 mm rod.
No, the SC cylinder does not lock or hold position without live air pressure. The adjustable cushion only decelerates the piston at stroke end. A mechanical lock or external rod brake is required to hold a vertical load safely.
