GQZ 5203‑KYY2 Double‑Row Angular Contact Agricultural Bearing 16.256×40×44.12mm Farm Planting Equipment Bearing

The 5203‑KYY2 double‑row angular contact ball bearing is a heavy‑duty special bearing for agricultural planting equipment. Equipped with KYY2 multi‑lip reinforced sealing structure, it effectively blocks soil, dust and moisture under harsh farm‑field operating conditions. Double‑row ball structure bears heavy combined radial and bidirectional axial loads, adapts to frequent impact and vibration generated during field operation.

It is widely used for seed drills, seeder gauge wheel, closing wheel and other agricultural machinery rotary assemblies.
