Product Description
503937 Tension sprocket (not assembled) is heavy-duty idler sprocket designed for CLAAS combine harvester chain transmission systems.
**Material features**: Made of high-grade alloy steel with quenched hardened teeth. Precision machined tooth profile delivers excellent wear resistance and impact toughness to endure continuous vibration and heavy loads under dusty field harvesting conditions.
**Product characteristics**: This tension sprocket serves as chain idler component. It adjusts chain tightness, absorbs transmission shock and keeps chain properly engaged to eliminate chain skipping and loosening. Important note: this product is sold unassembled, only the sprocket body. Bearings, bushings and other mounting accessories are not included and must be purchased separately. Worn or cracked sprocket teeth will cause unstable chain movement and interrupt grain conveying during harvest.
**Compatibility**: Direct aftermarket replacement matching OEM 503937, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Inspect chain condition before installation and adjust chain tension after assembly. Install 503937 tension sprocket to stabilize chain transmission of your Claas harvester.
