551997 Bearing Housing Assembled - Pre-assembled Cast Steel Bearing Base Suitable for Claas Combine

551997 Bearing housing assembled is complete pre-assembled bearing housing designed for CLAAS combine harvester straw chopper assemblies.

**Material features**: Made of high-strength cast steel with precision machined bore and mounting surface. Bearings and sealing components are pre-fitted inside the housing at factory. The housing delivers high rigidity and impact resistance, capable of enduring continuous vibration, straw residue and heavy shock loads in harsh field harvesting environments.

**Product characteristics**: This complete bearing housing assembly supports the straw chopper rotor and keeps bearings properly positioned. The integrated sealing structure prevents dust, crop debris and moisture from entering, while retaining lubricant inside. Cracked housing, worn or aged built-in seals will result in grease leakage and bearing contamination, causing rotor vibration and premature bearing failure.

**Compatibility**: Direct aftermarket replacement matching OEM 551997, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Calibrate rotor coaxiality during installation. Install 551997 bearing housing assembled to restore stable straw chopping performance quickly.
