Key Features
- OEM Tooth Profile and Material Grade — Manufactured to Husqvarna's exact specifications, with the correct tooth geometry and hardened steel construction required for dependable engagement under cutting loads.
- 1.2m Rack Length for Full-Travel Coverage — The 1.2-meter length matches the original rack dimension, supporting the full carriage travel range on compatible wall saw track systems.
- Broad Wall Saw Compatibility — Fits WS482HF, WS440HF, WS460, WS463, WS400, WS440, WS462, and WS482 wall saws, as well as the DS900 concrete core drill.
- Consistent Blade Carriage Tracking — A correctly functioning gear rack keeps the saw head moving smoothly and evenly along the track, which is essential for straight, accurate cuts through concrete, masonry, and reinforced structures.
- Drop-In Replacement — Designed to mount directly in place of the original rack without modification, simplifying service and getting equipment back into operation efficiently.
The gear rack is the toothed steel rail that meshes with the drive pinion on a wall saw's carriage motor, converting rotational power into controlled linear movement of the saw head along the track. When the rack is worn, chipped, or damaged, the carriage loses smooth, consistent travel — resulting in uneven cuts, skipping, or a complete loss of feed movement. Replacing a worn rack with a correct OEM unit restores accurate blade positioning and ensures the wall saw can deliver the straight, controlled cuts required for precision concrete work.
