This ball bearing supports a rotating shaft within the seeding technology assembly. It maintains the radial and axial alignment of the shaft, reducing friction between rotating and stationary components. A worn bearing produces play in the shaft, leading to uneven seed metering and eventual seizure of the rotating assembly. The 2RS designation indicates integral contact seals on both sides, which retain lubrication and exclude fine soil particles. When replacing, press the bearing onto the shaft using the inner race only; pressing on the outer race will damage the internal raceways.
