Key Features
- Genuine OEM Construction — machined to Husqvarna's original dimensional tolerances, ensuring the shaft seats, rotates, and transmits load exactly as the wall saw was engineered to perform.

- Broad Wall Saw Compatibility — fits the WS440, WS462, WS482, and WS440HF track-mounted wall saws, covering both standard and high-frequency variants in the WS series.
- Restored Drive Integrity — a worn or damaged shaft can introduce play, vibration, or misalignment into the cutting head; replacing it with this OEM part restores precise, stable operation through the full cutting cycle.
- Verified Part Number Fit — ordering by Husqvarna article number 505120401 confirms you are receiving the exact component specified for your machine, not a generic substitute.
A shaft in a wall saw transmits rotational force from the drive system to the cutting head, maintaining the alignment and power delivery needed for accurate, controlled cutting through concrete, masonry, and reinforced structures. When a shaft wears, bends, or develops surface damage, it can cause vibration, uneven blade tracking, and accelerated wear on bearings and adjacent components. Replacing a compromised shaft with a correctly specified OEM part restores the mechanical integrity of the drivetrain and allows the wall saw to perform consistent, precise cuts as intended.
