About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150CB
The B04-SC100X150CB is an AirTAC double-acting tie-rod cylinder built for construction machinery. The B04- prefix marks this as a construction-machinery dedicated variant of the SC100X150CB, meaning it is mechanically identical to the standard model but designated for heavy-equipment builders. It generates 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa.
This unit features a 100 mm bore, a 150 mm stroke, and a 25 mm piston rod. It includes adjustable cushions with a 29 mm cushion length to decelerate the piston at stroke ends. The CB rear double clevis mounting style allows for pivoting articulation, which is essential for heavy machinery linkages that require angular movement during operation.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150CB Is Used
Excavator Linkage Actuation
Drives secondary articulating arms or covers on heavy excavators, utilizing the CB rear double clevis to accommodate pivot geometry under high force.
Concrete Dispenser Gate
Opens and closes heavy discharge gates on concrete mixing equipment, relying on 5497 N of thrust at 0.7 MPa to move dense material loads.
Heavy Equipment Ladder Deployment
Extends and retracts access ladders or platforms on large construction vehicles, where the robust tie-rod construction withstands harsh outdoor environments.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X150CB the Right Cylinder?
This 100 mm bore cylinder provides 3927 N push force at 0.5 MPa. If your application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa; if you need more power, a 125 mm bore provides 6136 N at 0.5 MPa. For replacement matching, verify the 100 mm bore, 150 mm stroke, PT1/2 port thread, CB rear double clevis mount (part F-SC100CB), and confirm whether a built-in magnet is required.
At a 150 mm stroke, side-load stress on the 25 mm rod bearing is moderate, but always ensure the load is axially aligned. For heavy construction applications with potential shock loads or guiding requirements, use external mechanical guides 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-SC100X150CB FAQ
The B04- prefix indicates that this is an AirTAC construction-machinery dedicated cylinder. It is mechanically identical to the standard SC100X150CB, featuring the same 100 mm bore, 150 mm stroke, CB mounting, and force specifications, but is designated for heavy-equipment manufacturing.
No, this is a double-acting pneumatic cylinder and does not hold position or lock the load when air pressure is lost or exhausted. The adjustable cushion only decelerates the piston near the stroke end. A mechanical lock or external pilot-operated check valve is required to hold a load safely.
