The Husqvarna 574455801 Radial Seal is a genuine OEM component designed for the WS482HF, WS442, and WS482 wall saws. Sourced directly from Husqvarna, this seal meets the exact material grade and compression specifications required for reliable sealing performance in demanding wall sawing applications. It installs as a direct replacement for the original, ensuring proper fit within the wall saw's drive system without the need for adaptation. DHS Equipment supplies this part to help keep your wall saw operating at full capacity.
Key Features
- OEM-Grade Sealing Material — Manufactured to Husqvarna's compression and material specifications, ensuring the correct interference fit for the radial sealing surface in wall saw drive assemblies.
- Exact-Profile Replacement — Matches the original seal geometry for correct installation within the WS482HF, WS442, and WS482 drive housings — no rework or custom fitting required.
- Compatible With WS-Series Wall Saws — Verified fitment across the WS442, WS482, and WS482HF wall saws, covering both standard and high-frequency variants in the WS product line.
- Prevents Fluid Loss and Contamination — A properly seated radial seal keeps hydraulic or lubricating fluid contained and blocks contaminants from entering the drive system, protecting internal components from premature wear.
- Genuine Husqvarna Part — Carrying Husqvarna's OEM designation, this seal is the same component used in original assembly, giving you confidence in fit and sealing performance every time.
A radial seal forms a dynamic barrier between rotating and stationary components within a wall saw's drive assembly. It prevents lubricant or hydraulic fluid from escaping past the shaft while simultaneously blocking external debris, water, and slurry from entering the housing — conditions that are especially harsh in wall sawing environments. When a radial seal degrades or fails, fluid loss accelerates internal wear, and contamination can cause significant damage to bearings and other precision drive components. Replacing a worn seal promptly with the correct part restores the integrity of the assembly and protects the broader drivetrain.
