About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X2000S
The B04-SC100X2000S is an AirTAC double-acting tie-rod cylinder where the B04- prefix designates the construction-machinery dedicated variant of the SC100X2000S, sharing identical mechanical specs. It delivers 3927N of push force at 0.5MPa and up to 7068N at 0.9MPa.
This unit features a 2000mm stroke, which exceeds the 1500mm standard maximum for the 100mm bore, making it a non-standard made-to-order actuator. It includes a built-in magnet for CMSG/DMSG/EMSG sensors and a 25mm piston rod with PT1/2 ports.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X2000S Is Used
Excavator Boom Actuation
Drives auxiliary extension and positioning movements on heavy construction equipment where long reach and 7068N output force are required.
Heavy Equipment Gates
Opens and closes large access panels or sorting gates on crushing and screening machinery using its 2000mm travel distance.
Material Transfer Pusher
Stages large components or bulk material loads across wide construction machinery conveyors with reliable double-acting power.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X2000S the Right Cylinder?
At a 2000mm extension, the 25mm rod is highly susceptible to bending under side loads; an external guide rail or a dedicated guided cylinder is mandatory to prevent rod bearing damage. If less force is required, stepping down to an 80mm bore provides 2513N at 0.5MPa, while a 125mm bore offers 6136N for heavier lifting.
When replacing this cylinder, match the 100mm bore, 2000mm stroke, PT1/2 port thread, basic mounting, and the -S magnet option. The adjustable cushion is 29mm long to decelerate the piston near the end caps.
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-SC100X2000S FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SC100X2000S, offering the same 7068N thrust at 0.9MPa, 25mm rod, and PT1/2 ports without any physical dimension changes.
No, the SC series does not lock or hold position without live air pressure. A 2000mm stroke under load will drift or drop if pressure is lost; an external mechanical lock or pilot-operated check valve is required for holding.
