The present disclosure is directed to a pitch assembly for coupling a rotor blade to a hub of a wind turbine. In one embodiment, the pitch assembly includes a first pitch bearing having a first outer race and a first inner race rotatable relative to the first outer race via a first set of rolling elements, a second pitch bearing having a second outer race and a second inner race rotatable relative to the second outer race via a second set of rolling elements, and at least one spacer configured axially between and contacting the first and second pitch bea...
1. A rotor blade assembly for a wind turbine, comprising; a rotatable hub;at least one rotor blade configured with the rotatable hub and comprising a root end and a tip end, the at least one rotor blade defining a longitudinal axis from the root end to the tip end that is parallel with a pitch axis of the rotor blade; and,a pitch assembly coupling the root end of the rotor blade to the rotatable hub and configured to rotate the at least one rotor blade about the pitch axis, the pitch assembly comprising: a first pitch bearing having a first outer race an...
