About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC50X1000S
The B04-SC50X1000S is AirTAC's construction-machinery dedicated variant of the standard SC50X1000S. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base model, offering a 50mm bore and a 1000mm stroke. As a double-acting tie-rod cylinder, it provides a push force of 982 N at 0.5 MPa and 1767 N at 0.9 MPa.
This unit includes a built-in magnet (S suffix) for solid-state or reed sensor tracking along the barrel. It uses a 20mm piston rod, a PT1/4 port, and features 21mm adjustable cushions at both ends. With a body length A of 150mm, the total extended length reaches approximately 1150mm.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC50X1000S Is Used
Excavator Actuation
Drives auxiliary covers or separation gates on heavy equipment where a 982 N push force and 1000mm travel distance are required.
Concrete Form Handling
Extends and retracts molding pins or alignment arms in precast concrete machinery, utilizing the built-in magnet for position feedback.
Material Routing Gates
Shifts heavy diverter gates on construction site aggregate conveyors, benefiting from the 21mm adjustable cushions to soften impact at stroke ends.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC50X1000S the Right Cylinder?
At a 0.5 MPa operating pressure, this 50mm bore generates 982 N of push force. If your application requires less force, stepping down to a 40mm bore yields 628 N, while moving up to a 63mm bore provides 1559 N. The built-in magnet allows for precise end-of-stroke detection using CMSG, DMSG, or EMSG sensors.
Because this model features a 1000mm stroke, the extended 20mm rod is highly susceptible to bending under side loads. For heavy construction machinery, always use an external guide rail or a dedicated guided cylinder to support the load and prevent rod bearing damage. When replacing this unit, match the 50mm bore, 1000mm stroke, PT1/4 thread, basic mounting, and the magnetic piston option.
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.
