Product Description
551990 Bearing housing cover is robust protective end cover made for CLAAS combine harvester straw chopper bearing housing.
**Material features**: Constructed from high-strength cast steel or thick steel plate with precision machined sealing surface. It features good rigidity and abrasion resistance, resisting impact from straw and crop residues in dusty farm environments. The flat sealing surface ensures tight fit with bearing housing.
**Product characteristics**: This bearing housing cover is mounted on the outer side of straw chopper bearing housing. It provides physical protection, prevents dirt, straw debris and moisture from entering the bearing chamber, and stops lubricating grease leaking out. Cracked cover, worn sealing surface or distorted mounting holes will lead to grease loss and bearing contamination, resulting in premature bearing failure and straw chopper breakdown.
**Compatibility**: Direct aftermarket replacement matching OEM 551990, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Check sealing gaskets before installation, fasten bolts evenly to guarantee good sealing. Install 551990 bearing housing cover to protect your straw chopper bearings.
