Key Features
- OEM-Grade Tooth Geometry — Machined to Husqvarna's exact tooth profile specifications, ensuring smooth, consistent power transfer without slip or premature wear.

- Broad Wall Saw Compatibility — Confirmed fit across the WS440, WS440HF, WS442, WS460, WS462, WS463, and WS482 track-mounted wall saw range.
- Sustained Cutting Performance — A correctly seated gear wheel maintains consistent blade speed and torque delivery; a worn or damaged unit causes erratic cutting, excessive vibration, and accelerated drivetrain damage.
- Genuine Husqvarna Part — Supplied under the original Husqvarna part number 531123021, so you can verify the match against your machine's parts diagram with confidence.
The Gear Wheel is a core drivetrain component in Husqvarna wall saws, transmitting rotational force from the motor through the gear assembly to maintain consistent blade speed under load. When the gear wheel is in good condition, the saw tracks smoothly along its wall-mounted rail and delivers controlled, accurate cuts through concrete, masonry, and reinforced slabs. A worn or chipped gear wheel disrupts that power flow, producing vibration, uneven blade speed, and increased stress on surrounding drivetrain components — making timely replacement essential to maintaining cutting accuracy and protecting the wider gear system.
