The 6220‑2Z/C3 is single row deep groove ball bearing fitted with double non‑contact metal dust shields and C3 enlarged radial clearance. The C3 clearance compensates thermal expansion under high‑speed, high‑temperature operation, while ZZ shields block dust and retain internal grease. It bears combined radial and light bidirectional axial loads.
It is widely applied in large fans, heavy motors and industrial equipment running at elevated temperature.
