The structural features of the 420 stainless steel S6309ZZ deep groove ball bearing focus on material composition, sealing, raceway design, and cage construction, as detailed below:
Material Composition: Both inner and outer rings, along with rolling elements, are crafted from 420 stainless steel. This material offers excellent corrosion resistance and adequate hardness, making it suitable for humid or mildly corrosive environments.
Sealing Structure: Equipped with ZZ metal dust shields on both sides, stamped and secured within the outer ring groove. These effectively block dust and contaminants while minimizing internal grease leakage.
Core Design: Features a deep-groove raceway design, maximizing contact area between the raceway and rolling elements (steel balls) to simultaneously handle radial loads and bidirectional axial loads. An integrated stamped steel cage evenly separates the balls, reducing friction and maintaining operational stability.
