When disc openers start running hot, seizing, or wearing unevenly, the problem is often not the machine — it’s the bearing.
This 204PY3 bearing is widely used in planter and drill opener assemblies across John Deere, Kinze, Case-IH, Great Plains and other major brands. It is designed to withstand soil contamination, fertilizer exposure, and continuous radial load during planting seasons.
If you are sourcing a reliable replacement for worn or failed bearings, this solution helps you restore uptime quickly — without guessing compatibility.
