Abstract

A bearing assembly (30) is supported in a blade assembly such as a propeller (10), turbine or fan assembly and a blade assembly for a structure or craft having a hub having at least one blade opening (16), a blade (14) having an outer sleeve (18) received within the blade opening (16), and at least one preloaded bearing assembly (30) provided between the outer sleeve (18) and the hub (12) and where the at least one preloaded bearing assembly (30) is preloaded by means of a wedge assembly, allows the blade (14) to rotate within the hub (12) and is subject to the effects of rotational centrifugal force acting on the blade (14).
