About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X175S
The B04-SC40X175S is an AirTAC double-acting tie-rod cylinder engineered for construction machinery. The B04- prefix designates this as the construction-machinery dedicated variant of the standard SC40X175S, retaining identical mechanical specifications, dimensions, and force output.
Delivering 628N of push force at 0.5 MPa and 1130N at 0.9 MPa, it is built for robust actuation. This 40mm bore model features a 16mm piston rod, PT1/4 ports, and 21mm adjustable cushions. The built-in S suffix magnet allows CMSG, DMSG, or EMSG sensors to track piston position along the 142mm body length.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X175S Is Used
Heavy Equipment Doors
Actuates and secures access panels on excavators and loaders where 879N of thrust at 0.7 MPa is sufficient for smooth operation.
Material Handling Arms
Drives positioning arms on compact construction machinery, using the built-in magnet to confirm stroke endpoints for safety interlocks.
Clamping Fixtures
Provides reliable clamping force of 1130N at 0.9 MPa for holding steel components during heavy-duty welding or assembly processes.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X175S the Right Cylinder?
This 40mm bore provides 628N push at 0.5 MPa; step down to a 32mm bore for 402N if the load is lighter, or up to a 50mm bore for 982N if you need more thrust. For replacements, match the 40mm bore, 175mm stroke, PT1/4 port thread, basic mounting, and the built-in magnet. Note that the SC is a tie-rod design and is shorter than ISO 15552 cylinders, so it is not a direct dimensional replacement for them.
With a 175mm stroke, side loads can exert leverage on the 16mm rod bearing. If the mechanism cannot be perfectly aligned, 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-SC40X175S FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated variant of the SC40X175S cylinder. It is mechanically identical to the standard model, offering the same 40mm bore, 175mm stroke, and 1130N thrust at 0.9 MPa.
No, the SC series is double-acting and does not lock position without live air pressure. The adjustable cushion only decelerates the piston near the stroke end. A mechanical lock or external rod brake is required to hold vertical loads safely.
