Double row ball bearings are a type of rolling-element bearing that consists of two rows of balls placed in between two inner and outer raceways. This design allows them to accommodate radial and axial loads in both directions simultaneously. The inner ring is typically mounted on a shaft, while the outer ring remains stationary. The two rows of balls provide increased load-carrying capacity compared to single-row ball bearings, making them suitable for applications requiring higher radial and axial loads or where shaft misalignment may occur.
