About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC80X225S
The B04-SC80X225S is an AirTAC double-acting tie-rod pneumatic cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the SC80X225S. It is mechanically identical to the standard SC line, delivering 2513 N of push thrust at 0.5 MPa and 3518 N at 0.7 MPa.
Featuring a 25 mm piston rod, PT3/8 port, and 28 mm adjustable cushions, this unit handles a 225 mm stroke efficiently. The S suffix indicates a built-in magnet for CMSG/DMSG/EMSG sensor integration on the 182 mm body.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC80X225S Is Used
Excavator Actuation
Drives auxiliary covers and locking arms on heavy construction equipment requiring robust 3518 N force at 0.7 MPa.
Concrete Dispenser
Operates flow gates on batching plants, using the built-in magnet to confirm valve open/closed positions.
Heavy Equipment Hoods
Lifts and secures heavy access panels on cranes or loaders, benefiting from the 28 mm adjustable cushions.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC80X225S the Right Cylinder?
This 80 mm bore provides 2513 N push force at 0.5 MPa. Step down to a 63 mm bore (1559 N push) for lighter loads, or up to a 100 mm bore (3927 N push) for heavier machinery demands. For replacement, match the 80 mm bore, 225 mm stroke, PT3/8 port, basic mounting, and the built-in magnet.
With a 225 mm stroke, side-load bending on the 25 mm rod is moderate but manageable. For heavy construction loads, use an external guide or a guided cylinder to prevent rod-bearing 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-SC80X225S FAQ
The B04- prefix marks this as AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SC80X225S, offering the same 80 mm bore, 225 mm stroke, and 2513 N push force at 0.5 MPa.
No, the adjustable cushion only decelerates the piston near stroke end and does not lock the rod. To hold a vertical load without live pressure, you must use an external rod brake or a pilot-operated check valve.
