About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC50X150S
The B04-SC50X150S is AirTAC's construction-machinery dedicated variant of the standard SC50X150S tie-rod cylinder, sharing identical mechanical specs. The B04- prefix simply designates its deployment in heavy-equipment builds rather than altering its physical dimensions. As a double-acting pneumatic actuator, it provides a push force of 982 N at 0.5 MPa and 1767 N at 0.9 MPa.
Featuring a 20 mm piston rod and a 150 mm stroke, this unit includes a built-in magnet for position sensing. The barrel measures 150 mm in body length A, and adjustable cushions provide 21 mm of deceleration at stroke ends to absorb impact energy.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC50X150S Is Used
Excavator Accessory Actuation
Drives secondary attachment movements on heavy excavators where a 1767 N output at 0.9 MPa is sufficient for latching or positioning components.
Concrete Dispenser Gates
Opens and closes discharge gates on concrete mixing equipment, utilizing the built-in magnet to confirm gate status via CMSG sensors.
Heavy Equipment Latching
Secures and releases heavy access panels or counterweights on cranes and loaders, relying on adjustable cushions to soften stroke impact.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC50X150S the Right Cylinder?
This 50 mm bore generates 982 N of push force at 0.5 MPa. If your construction mechanism requires less actuation force, stepping down to a 40 mm bore yields 628 N, while moving up to a 63 mm bore provides 1559 N. For replacement matching, verify the 50 mm bore, 150 mm stroke, PT1/4 port thread, basic mounting style, and the -S magnet option.
At a 150 mm stroke, side loads can stress the rod bearing. For heavy construction applications involving pivoting or offset loads, use an external guide rail or 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-SC50X150S FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SC50X150S, offering the same 50 mm bore, 150 mm stroke, and 1767 N thrust at 0.9 MPa.
No, the SC series is double-acting and cannot hold position without live air pressure. A mechanical lock, external rod brake, or pilot-operated check valve is required to maintain a load safely.
