Split tapered roller bearing

A bearing assembly comprising:

• a split inner race ring having first and second components configured to be installed and connected together on a shaft, each component of the split inner race ring defining two raceways for supporting rolling elements in a two-row orientation, and a central rib between the two raceways;
• wherein the first and second components of the split inner race ring mate at a V-shaped split line;
• a first split outer race ring having first and second components configured to be installed around the shaft, each component of the first split outer race ring defining a raceway for supporting a first row of the two rows of rolling elements;
• and
• a second split outer race ring having first and second components configured to be installed around the shaft, each component of the second split outer race ring defining a raceway for supporting a second row of the two rows of rolling elements;
• wherein the central rib includes a rib face along which the rolling elements slide, and wherein at the V-shaped split line, the rib face has a relief formed at an outer diameter portion of the rib face that is larger than any relief formed at an inner diameter portion of the rib face.
