Product Description
551886 Bearing housing straw choppers is robust cast steel bearing housing specially designed for CLAAS combine harvester straw chopper assemblies.
**Material features**: Made of high-strength cast steel with precision machining on mounting surfaces and bearing bore. It features high structural rigidity and shock resistance, capable of enduring heavy impact loads, straw debris and continuous vibration in harsh field working conditions.
**Product characteristics**: This bearing housing serves as the mounting base for bearings inside the straw chopper. It supports the rotating chopper rotor, holds bearings in position and absorbs impact force generated during straw cutting. Cracked housing, distorted mounting holes or worn seating surface cause rotor eccentricity, severe vibration and premature bearing failure, leading to breakdown of straw chopping function.
**Compatibility**: Direct aftermarket replacement matching OEM 551886, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Inspect bearings and oil seals, calibrate rotor coaxiality after installation. Install 551886 bearing housing to restore reliable straw chopping performance for your Claas harvester.
