Custom cast iron agricultural ring
Our custom cast iron agricultural rings are precision sand-cast for planting equipment, seeding machinery, and tillage implements. Designed to function as press wheel rings, sprocket drive rings, and seed meter components, each ring features a precision tooth profile and custom bore to match your specific planter or seeder model. Available in grey iron and ductile iron, fully customizable in outer diameter, tooth count, tooth profile, and spoke configuration. OEM and ODM orders supported with sample production available before mass order commitment.
*Provide your application requirements—such as stress conditions, materials, size range, and even product name. We are always available for customization, so please contact us directly.
Introduction
Why Choose Our Cast Iron Agricultural Rings?
Precision Tooth Profile for Positive Drive — Each tooth is cast and finish-machined to your exact profile specification, ensuring reliable chain or belt engagement with minimal backlash and consistent seed spacing in row crop planting applications.
Custom Tooth Count & Outer Diameter — Whether you need a 24-tooth sprocket ring for a standard corn planter or a custom-count ring for specialty seeding equipment, we manufacture to your exact drawing without tooling limitations.
3-Spoke Lightweight Design — The curved 3-spoke web design reduces overall weight while maintaining structural rigidity, minimizing soil compaction and rolling resistance in field conditions.
Grey Iron & Ductile Iron Options — Grey iron offers excellent wear resistance and cost efficiency for standard planting season service life, while ductile iron provides higher impact and fatigue resistance for rocky soil and high-speed planting operations.
Corrosion & Wear Resistant Finish — Black lacquer and phosphating finish options available to protect against soil moisture, fertilizer contact, and seasonal storage corrosion, extending service life across multiple growing seasons.
