Zusammenfassung:	The present disclosure is directed to a pitch assembly 102 for coupling a rotor blade 22 to a hub 20 of a wind turbine 10. In one embodiment, the pitch assembly 102 includes a first pitch bearing 104 having a first outer race 112 and a first inner race 114 rotatable relative to the first outer race 112 via a first set of rolling elements 108, a second pitch bearing 106 having a second outer race 116 and a second inner race 118 rotatable relative to the second outer race 116 via a second set of rolling elements 110, and at least one spacer 120,122 configured axially between and contacting the first and second pitch bearings 104,106. Further, at least a portion of the first pitch bearing 104 and at least a portion of the second pitch bearing 106 are axially aligned between the rotatable hub 20 and the rotor blade 22 in a generally span-wise direction.
