Key Features
- OEM Seal Material Grade — manufactured to Husqvarna's compression and material specifications, delivering the sealing integrity these high-demand cutting and drilling applications require.
- Complete Set for Full Service — includes all shaft seals needed for a thorough service interval, so every sealing point is addressed in a single repair.
- Broad Fitment Across Wall Saw and Core Drill Families — confirmed fit for WS462, WS460, and WS463 wall saws as well as the DM406 concrete core drill, covering multiple machine families with one part.
- Prevents Fluid Loss and Contamination — correctly seated shaft seals stop hydraulic fluid or lubricant from escaping and prevent debris ingestion, keeping internal components protected during heavy cutting and drilling cycles.
- Direct Drop-In Replacement — dimensioned to match the original Husqvarna seals exactly, so the set installs into existing housings and shaft bores without modification.
Shaft seals form a critical barrier around rotating shafts, preventing lubricating fluids from leaking out and stopping contaminants such as water, concrete slurry, and dust from entering the machine's internal assemblies. In wall saws and core drills, these seals are exposed to significant rotational stress and wet, abrasive cutting environments, making their condition directly tied to the longevity of bearings, gears, and other internal components. When shaft seals wear or fail, fluid loss accelerates internal wear and contamination can quickly cause damage to surrounding assemblies — making timely replacement with a correctly specified seal set essential to sustained machine performance.
