This bearing assembly supports a rotating shaft within the fertilizer spreader’s metering or disc drive system. The housing provides a sealed mounting point that aligns the bearing with the shaft axis and protects the rolling elements from dust and fertilizer granules. A worn bearing allows radial play that can cause uneven material distribution or vibration in the driveline. The unit is a direct replacement for the original factory component, maintaining the same housing geometry and shaft clearance as the assembly it replaces.
