About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X450
The B04-SC100X450 is AirTAC's construction-machinery dedicated variant of the standard SC100X450 tie-rod cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base SC100X450, offering a 100mm bore and 450mm stroke. As a double-acting actuator, it delivers 3927N of push force at 0.5 MPa and reaches 7068N at 0.9 MPa.
This model features a 25mm piston rod, PT1/2 port threads, and adjustable cushions with a 29mm length to decelerate the piston at stroke ends. The total extended length is approximately 638mm (body length A 188mm + 450mm stroke). It uses standard TPU seals rated for -20 to +70 C.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X450 Is Used
Excavator Accessory Actuation
Drives heavy auxiliary attachments on earthmoving equipment, utilizing its 7068N push force at 0.9 MPa to pivot or lock structural components.
Concrete Pump Positioning
Shifts and secures discharge chutes or distribution valves on concrete pumping machinery, where the 29mm adjustable cushion softens high-impact strokes.
Heavy Equipment Bracing
Extends 450mm to deploy stabilizer legs or mechanical braces on mobile cranes and heavy construction vehicles before lifting operations.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X450 the Right Cylinder?
This 100mm bore provides 3927N push force at 0.5 MPa. If your construction machinery requires less force, stepping down to an 80mm bore yields 2513N. If you need higher force for heavy lifting, the 125mm bore offers 6136N at 0.5 MPa. Ensure your directional valve and air supply can handle the required volume.
With a 450mm stroke, the 25mm rod is subject to bending under side loads. For construction equipment applications, use an external guide rail or a guided cylinder to prevent rod-bearing damage. When ordering a replacement, match the 100mm bore, 450mm stroke, PT thread, basic mounting, and no-magnet configuration exactly.
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-SC100X450 FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SC100X450, featuring the same 100mm bore, 450mm stroke, 25mm rod, and 7068N thrust at 0.9 MPa, with no changes to physical specifications.
No. This is a double-acting air cylinder and does not lock or hold position without live air pressure. The adjustable cushion only decelerates the piston at stroke ends. To hold a vertical load safely on construction machinery, you must use an external mechanical lock or pilot-operated check valve.
