ABSTRACT:
Multiple balancing plugs (114) preferably have a common length and a common offset center of gravity (130) in the length dimension for providing dual plane balancing of a rotatable body (100). The rotatable body (100) includes a plurality of balancing plug holes (112a–f) for receipt of a balancing plug (114) as desired/required to address an imbalance associated with the rotatable body (100). One or more balancing plugs (114) may be disposed within the rotatable body (100) in a first orientation such that their respective centers of gravity (130) are disposed within a first plane (134). One or more balancing plugs (114) may be disposed within the rotatable body (100) in a second, opposite orientation such that their respective centers of gravity (130) are disposed within a second plane (138) that is spaced from the first plane (134).
