Abstract
In a wheel rolling bearing device, where a pitch diameter of the inner-row ball set is D1 and a pitch diameter of the outer-row ball set is D2, D1 and D2 are set so as to satisfy the relationship 'D1<D2'. Where an angle of a raceway circular arc from an intersection point of each inner-row ball with the inner-side outer ring raceway surface at a contact angle to a boundary portion of an inner-side raceway shoulder is θ1 and an angle of a raceway circular arc from an intersection point of each outer-row ball with the outer-side outer ring raceway surface at a contact angle to a boundary portion of an outer-side raceway shoulder is θ2, θ1 and θ2 are set so as to satisfy the relationship 'θ1<θ2'.
