About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X175
The B04-SC100X175 is AirTAC's construction-machinery dedicated variant of the standard SC100X175 tie-rod cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base SC100X175, offering a 100mm bore and 175mm stroke with a 25mm piston rod.
This double-acting pneumatic cylinder delivers a robust 7068N of push thrust at 0.9 MPa, making it highly capable of driving heavy structural components. It features a 188mm body length A, 29mm adjustable cushions to soften end-of-stroke impact, and PT1/2 porting.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X175 Is Used
Heavy Equipment Actuation
Drives robust covers, access hatches, and locking pins on excavators and loaders where high impact resistance and 7068N thrust at 0.9 MPa are required.
Concrete Pump Controls
Actuates heavy-duty valves and flow diverters on concrete pumping rigs, utilizing the 29mm adjustable cushions to absorb sudden shifts in material flow.
Harvester Component Shift
Positions heavy cutting heads and grain deflectors on large combine harvesters, relying on the durable TPU seals for outdoor temperature extremes.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X175 the Right Cylinder?
This 100mm bore provides 3927N at 0.5 MPa. If your application requires less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa. For heavier loads, a 125mm bore offers 6136N at 0.5 MPa. Ensure your directional valve and air supply can adequately feed the PT1/2 port to maintain speed.
When replacing this unit, match five key points: 100mm bore, 175mm stroke, PT1/2 port thread, basic mounting (or the specific F-SC100 accessory used), and the absence of a magnet. Because the 175mm stroke is under 300mm, side-load bending stress on the 25mm rod is moderate, but external guides are still recommended for heavy off-road machinery pivots.
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.
