About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC63X500S
The B04-SC63X500S is an AirTAC construction-machinery dedicated variant of the standard SC63X500S double-acting tie-rod cylinder. The B04- prefix designates its deployment in heavy-equipment builds, while the physical specifications remain mechanically identical to the base SC series.
Delivering a push force of 1559 N at 0.5 MPa and 2805 N at 0.9 MPa, this 63 mm bore unit features a 500 mm stroke and a 20 mm piston rod. The built-in S suffix magnet allows CMSG or DMSG sensors to track position along the 153 mm body length.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC63X500S Is Used
Heavy Equipment Actuation
Drives robust covers and access panels on construction machinery where the B04 designation ensures suitability for demanding heavy-equipment environments.
Material Handling Gates
Extends 500 mm to operate large sorting gates or deflectors on aggregate and bulk material conveyors requiring 1559 N at 0.5 MPa.
Clamping Fixtures
Provides reliable 2805 N clamping force at 0.9 MPa for securing large steel fabrications during welding or machining processes.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC63X500S the Right Cylinder?
If 1559 N at 0.5 MPa is insufficient, stepping up to the 80 mm bore yields 2513 N; if it is excessive, the 50 mm bore provides 982 N. For this 500 mm stroke, the unsupported 20 mm rod is susceptible to bending under side loads, requiring an external guide or a guided cylinder to prevent premature rod-bearing wear.
When sourcing a replacement, match these five points: 63 mm bore, 500 mm stroke, PT1/4 port thread, basic mounting, and the built-in magnet. The adjustable cushion is 28 mm to decelerate the piston near 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-SC63X500S FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated variant of the SC63X500S. It is mechanically identical to the standard SC cylinder, offering the same 63 mm bore, 500 mm stroke, and 2805 N force at 0.9 MPa.
No, the SC cylinder does not lock or hold position when air pressure is lost. The adjustable 28 mm cushion only decelerates the piston near stroke ends. To hold a vertical load safely, an external mechanical lock or pilot-operated check valve is required.
