Key Features
- OEM-Grade Precision Tolerancing — Manufactured to Husqvarna's original dimensional and load specifications, ensuring the bearing seats correctly and handles the rotational demands of a walk-behind floor saw.
- Direct Drop-In Replacement — Engineered to match the original mounting interface on the FS400LV, allowing straightforward installation without reworking surrounding components.
- Designed for the FS400LV Floor Saw — Fitment is confirmed for the FS400LV walk-behind flat saw, making part selection straightforward for operators and service technicians alike.
- Restored Smooth Rotation — A worn or failed bearing introduces vibration, heat buildup, and uneven blade drive; this replacement restores smooth, stable rotation to the drivetrain or blade arbor where it is installed.
- Protects Adjacent Components — Correct bearing preload and seating prevents premature wear on shafts, housings, and seals, extending the service life of surrounding assemblies.
A bearing reduces friction between rotating and stationary machine components by providing a precision rolling interface that supports radial and axial loads. In a walk-behind floor saw like the FS400LV, bearings are critical to maintaining accurate blade alignment, consistent cutting depth, and smooth power transmission through the drivetrain. When a bearing wears or fails, the resulting play and heat generation can damage shafts and housings rapidly, making timely replacement essential to restoring full cutting performance.
