The 4304-B-TVH Double-row deep groove ball bearings mainly consist of an integral inner ring, an integral outer ring, two rows of balls, and a cage. The raceways are deep grooves, with the balls making four-point contact with the raceways. The inner and outer rings are typically integrated, resulting in a compact structure.

A single set of double-row deep groove ball bearings can simultaneously withstand radial and bidirectional axial loads, eliminating the need for paired installation. They offer higher load-carrying capacity than single-row deep groove ball bearings and excellent rigidity. The integral structure simplifies installation, saves space, and is suitable for applications requiring high axial positioning.
