Deep Groove Ball Bearing (DGBB) is one of the most widely used bearing types in the global industrial field, complying with international standards such as ISO and ANSI. It features a simple structure consisting of an inner ring, outer ring, a set of steel balls, and a cage. The key structural characteristic is its deep, arc-shaped raceway on both the inner and outer rings, which matches the curvature of the steel balls to a high degree.
This design allows the bearing to operate at high speeds while bearing both radial loads and moderate axial loads (in both directions). Unlike outer spherical bearing units, it is a standalone bearing component without an integrated housing, requiring matching mounting structures or bearing seats for installation. Available in open, shielded (Z/ZZ), or sealed (2RS/2RS1) configurations, it can be tailored to different protection and lubrication needs across application scenarios.
