About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X100S
The B04-SC100X100S is AirTAC's construction-machinery dedicated variant of the standard SC100X100S pneumatic cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base SC single-rod, double-acting tie-rod cylinder. It features a 100mm bore and a 100mm stroke.
This model generates 3927 N of push thrust at 0.5 MPa and reaches 7068 N at 0.9 MPa. The 25mm piston rod uses an M20x1.5 thread, and the body length A is 188mm. The S suffix indicates a built-in magnet for position sensing, while the adjustable cushion measures 29mm to soften end-of-stroke impact.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X100S Is Used
Excavator Doors
Actuates heavy cab doors and access panels on earthmoving equipment where high force and reliable cycling are required.
Concrete Dispensers
Drives the diverter valves on concrete mixing trucks, handling the high thrust needed to route viscous materials.
Boom Lockouts
Engages secondary safety locks and mechanical stops on telescopic booms and crane extensions.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X100S the Right Cylinder?
Select this 100mm bore when 50mm (982 N at 0.5 MPa) or 80mm (2513 N at 0.5 MPa) cylinders lack the force for heavy construction rigging. At 100mm stroke the side-load risk is moderate, but always verify rod-bearing loads. For exact replacements, match the 100mm bore, 100mm stroke, PT1/2 port, basic mounting, and the S magnet 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.
Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X100S FAQ
The B04- prefix marks this as AirTAC's construction-machinery dedicated line. The B04-SC100X100S is mechanically identical to the standard SC100X100S, offering the same 100mm bore, 100mm stroke, and 7068 N thrust at 0.9 MPa.
No. The SC series is double-acting and does not lock or hold position without live air pressure. The adjustable cushion only decelerates the piston near the stroke end. For vertical loads, you must use an external rod brake or pilot-operated check valve.
