About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150CA
The B04-SC100X150CA is an AirTAC double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa and a maximum theoretical output of 801 kgf. The B04- prefix designates this as a construction-machinery dedicated variant, mechanically identical to the standard SC100X150CA but targeted for heavy-equipment builders. It features a 100 mm bore, a 150 mm stroke, and a robust 25 mm piston rod.
This unit comes equipped with a CA rear single clevis mounting style (part code F-SC100CA) for pivoting articulation on machinery. It uses standard TPU seals rated for -20 to +70 C, PT1/2 port threads, and adjustable cushions measuring 29 mm to absorb end-of-stroke impact.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150CA Is Used
Excavator Accessory Actuation
Drives secondary articulating arms or covers on heavy excavating equipment, utilizing the CA clevis to accommodate pivot geometry during operation.
Concrete Pump Positioning
Shifts delivery booms or valve components on concrete pumps where the 3927 N push force at 0.5 MPa easily overcomes mechanical friction.
Heavy Equipment Gates
Opens and closes heavy access panels or discharge gates on loaders and cranes, relying on the 25 mm rod for durable push-pull cycles.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150CA the Right Cylinder?
Select this 100 mm bore cylinder when your application requires roughly 3927 N of push force at 0.5 MPa; if you need less force, step down to the 80 mm bore (2513 N), or step up to the 125 mm bore (6136 N) for heavier loads. Because this model features a CA rear clevis, ensure your mounting frame accommodates a single pivoting lug.
For replacements, match the 100 mm bore, 150 mm stroke, PT1/2 port thread, CA clevis mounting, and non-magnet configuration exactly. While the 150 mm stroke is moderate, always verify that side loads are managed by external guides to prevent rod bearing wear, as the cylinder itself does not lock or hold position without live air pressure.
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-SC100X150CA FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated cylinder. It is mechanically and dimensionally identical to the standard SC100X150CA, featuring the same 100 mm bore, 150 mm stroke, CA clevis mount, and 3927 N push force at 0.5 MPa.
No, the SC series is a double-acting air cylinder and cannot hold position without live pressure. The adjustable cushion only decelerates the piston at stroke ends; a mechanical lock or external pilot-operated check valve is required to hold loads safely.
