About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X250STC
The B04-SC100X250STC is an AirTAC double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa. The B04- prefix designates this as a construction-machinery dedicated variant, mechanically identical to the standard SC100X250STC, built for heavy-equipment builders. It features a 100 mm bore and a 250 mm stroke.
This model includes a built-in magnet for CMSG/DMSG/EMSG sensor tracking and a TC centre-trunnion mount (supplied with the TCM1 bracket) for pivoting loads. With a 25 mm rod diameter and 29 mm adjustable cushioning, it handles robust actuation tasks up to a maximum operating pressure of 1.0 MPa.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X250STC Is Used
Heavy Equipment Pivot
Ideal for construction machinery articulation joints requiring a centre-trunnion pivot to swing heavy linkages through a 250 mm arc.
Industrial Press Clamping
Provides 3927 N of clamping force at 0.5 MPa for securing large fabrications or heavy steel components during machining or welding.
Material Handling Gates
Drives heavy-duty loading ramps or aggregate hopper doors on mobile plant equipment where sensor feedback via the built-in magnet is required.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC100X250STC the Right Cylinder?
Select this 100 mm bore when 3927 N at 0.5 MPa is required; step down to an 80 mm bore (2513 N) for lighter loads, or up to a 125 mm bore (6136 N) for heavier pushing. At a 250 mm stroke, side-load bending on the 25 mm rod bearing is a factor—use an external guide or a guided cylinder to prevent premature wear if the load is not perfectly axial.
For exact replacement matching, verify the 100 mm bore, 250 mm stroke, PT port thread, TC centre-trunnion mounting (F-SC100TC bracket), and the -S built-in 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-SC100X250STC FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SC100X250STC, offering the same 100 mm bore, 250 mm stroke, and 3927 N force at 0.5 MPa, simply designated for heavy-equipment builders.
No, the SC series is double-acting and does not hold position when air is exhausted. The adjustable cushion only decelerates the piston at stroke end. For vertical loads, you must use an external rod brake, mechanical lock, or pilot-operated check valve.
