About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200
The B04-SC100X200 is AirTAC's construction-machinery dedicated variant of the standard SC100X200 tie-rod cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base SC100X200. This double-acting pneumatic cylinder provides a robust 3927 N of push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa.
Featuring a 100 mm bore and 200 mm stroke, it uses a 25 mm piston rod and PT1/2 ports. The adjustable cushioning spans 29 mm to decelerate heavy loads smoothly. With a body length A of 188 mm, the total extended length reaches approximately 388 mm. Standard TPU seals support operating temperatures from -20 to +70 C.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200 Is Used
Heavy Equipment Actuation
Drives robust linear motions on construction machinery, such as opening heavy access panels or actuating secondary hydraulic bypass valves.
Industrial Pressing
Provides reliable downward pressing force for assembling heavy-duty mechanical components and bearings in manufacturing cells.
Material Diversion
Pushes large aggregate or bulk material loads on heavy-duty conveyor systems within harsh processing environments.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X200 the Right Cylinder?
This 100 mm bore is a significant step up from the 80 mm class (2513 N push at 0.5 MPa), making it ideal when your application demands higher thrust. If 3927 N is excessive, stepping down to the 80 mm bore saves space and air consumption. For replacements, ensure an exact match on bore, stroke, port thread (PT or G), mounting accessory, and magnet option (-S).
At a 200 mm stroke, side-load stress on the 25 mm rod bearing is moderate but manageable. For heavy off-road or construction-machine pivoting loads, verify that the load is guided externally or consider a guided cylinder to prevent rod bending and premature seal 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-SC100X200 FAQ
The B04- prefix indicates this is a construction-machinery dedicated variant of the SC100X200. It is mechanically identical to the standard SC100X200, offering the same 100 mm bore, 200 mm stroke, and 7068 N thrust at 0.9 MPa, but is designated for heavy-equipment builders.
At 0.5 MPa operating pressure, it delivers 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
