306501001 Zaffrani gathering chain tension sprocket, Z=15

306501001 is the original part number for a plastic tensioning sprocket (Sprocket Z=15) used in the gathering chain conveyor of agricultural machinery manufactured by the Italian company Zaffrani.
It serves as a guide and tensioning component for the gathering chains, which grip and advance crop stalks into the working area of ​​the header.

⚙️ Technical Specifications

• Number of teeth (Z): 15.
• Material: High-strength, wear-resistant plastic (polyamide/caprolon). The use of plastic reduces the overall weight of the assembly, lowers friction, and prevents wear on the metal gathering chain itself during operation.
• Function: Ensures proper chain tension and smooth movement, preventing the chain from slipping off or becoming misaligned under high loads.

🚜 Equipment Compatibility

This sprocket is a standard consumable part for Zaffrani harvesting equipment, including:
• Zaffrani Maisflow corn headers (models ZF/670/675, ZF 870/875, ZF 1250/1270, etc.).
• Drive system and tensioner components for various other types of row-independent headers from the same brand (e.g., those designed for sunflower harvesting).

💡 Operational Notes

These plastic sprockets are constantly exposed to plant sap, dirt, and dust. Over time, the teeth may wear down, or play (looseness) may develop in the bearing seat. If a worn component is not replaced in a timely manner, the resulting slack in the gathering chain can cause it to jam, potentially leading to a drive failure or serious damage to the header’s row-unit gearbox.
