The invention relates to a wheel bearing unit (1, 4) having at least one outer part (8, 21), having at least one inner part (10) and having at least two rows of rolling bodies (11) between the outer part (8, 21) and the inner part, wherein in each case at least one inner raceway (15, 16) is formed on the outer part (8, 21) and in each case at least one outer raceway (13, 14) is formed on the inner part (10) for the rolling bodies (11) of one row. A ratio of the diameter (TK) of the reference circle of at least one row of the wheel bearing unit (1, 4) to the diameter (dk) of the rolling bodies (11) of the respective row is greater than the numerical value six. The row spacing (rL) between the rows corresponds to at most 1.65 times the diameter (d k) of the rolling bodies (11).
