Key Features
- OEM-Matched Dimensional Tolerance — Machined to Husqvarna's exact keyway specification, this key seats flush and transfers torque without play or fretting that can develop with undersized alternatives.
- Drop-In Keyway Fit — Sized to slot directly into the shaft keyway on compatible wall saw assemblies, requiring no grinding, shimming, or custom fitting during installation.
- Broad Wall Saw Compatibility — Fits the WS440, WS440HF, WS442, WS460, and WS482 wall saws, covering the core WS-series track-mounted cutting lineup.
- Torque Transmission Integrity — A correctly fitted key locks the drive component to the shaft so power transfers cleanly; a worn or missing key causes slippage, erratic blade speed, and accelerated shaft damage.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, ensuring the material grade and geometry match the original production specification.
A key is a small, precision-machined component that sits in a machined slot — called a keyway — cut into both a shaft and the hub of a mating part such as a sprocket, pulley, or gear. Its role is to create a positive mechanical lock between the two components, preventing relative rotation so that torque is transmitted from the shaft to the driven part without slippage. On a wall saw like the WS460 or WS482, where drive components must handle sustained cutting loads through reinforced concrete, a correctly fitted key is essential to consistent blade speed and cutting control. When a key shears, deforms, or goes missing, the driven component can spin freely on the shaft, causing loss of blade power, uneven cuts, and rapid wear to the surrounding keyway surfaces.
