Document Type and Number:
WIPO Patent Application WO/2012/082630

Abstract:
A double bearing assembly is for supporting a rotatable shaft within a housing and includes two axially-spaced inner races mounted on the shaft. Each inner race has an outer race surface with a radially-outwardly extending shoulder section adjacent one axial end and are arranged such that the two shoulder surfaces are facing. Two axially-spaced outer races are disposed within the housing, each about one of the inner races. Each outer race has an inner race surface with a radially-inwardly extending shoulder section adjacent one end and are arranged such that the two shoulder surfaces face away from each other. A set of rolling element are disposed between each pair of races. At least one biasing member biases one of the outer races axially to retain the associated rolling elements sandwiched between the inner shoulder surface of the outer race and the outer shoulder surface of the corresponding inner race.
