About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC80X350S
The B04-SC80X350S is an AirTAC double-acting tie-rod pneumatic cylinder engineered for construction machinery. The B04- prefix designates this as a construction-machinery dedicated variant of the standard SC80X350S, meaning it is mechanically identical to the base model with an 80mm bore and 350mm stroke.
Delivering a robust 3518N of push force at 0.7MPa, this unit handles heavy equipment actuation with ease. The built-in magnet allows for precise position sensing using CMSG or DMSG reed switches along the 182mm body length, while the 28mm adjustable cushions absorb impact at stroke ends.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC80X350S Is Used
Heavy Equipment Doors
Actuates robust access panels and cab doors on excavators and loaders where high force and durable construction-machinery specification are required.
Concrete Dispensing
Drives diverter gates and valves on mobile batching equipment, using the magnetic piston to confirm open/closed positions in dusty environments.
Implement Positioning
Provides reliable linear motion for adjusting heavy implements and stabilizer arms on large tractors and earthmoving machinery.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC80X350S the Right Cylinder?
This 80mm bore provides 3518N push at 0.7MPa; if your application requires less force, stepping down to a 63mm bore yields 2182N. For heavier loads, a 100mm bore offers 5497N. Because this model features a 350mm stroke, the 25mm rod is susceptible to bending under side loads—use external guides or a guided cylinder to prevent rod bearing damage.
When replacing this cylinder, match these five attributes: 80mm bore, 350mm stroke, PT3/8 port thread, basic mounting, and the built-in magnet (S suffix). It is a tie-rod design, shorter than an ISO 15552 cylinder, so verify dimensions before swapping.
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-SC80X350S FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated cylinder. It is mechanically identical to the standard SC80X350S, offering the same 80mm bore, 350mm stroke, and 3518N push force at 0.7MPa, but is designated for heavy-equipment builders.
No, the SC series does not hold position without live air pressure. The adjustable cushions only decelerate the piston at stroke ends. For vertical loads that must be held during pressure loss, you must use an external rod brake or pilot-operated check valve.
