ABSTRACT:
A roller cone drill bit may include optimally designed bearing structures and cutting structures. The roller cone drill bit may include three cone assemblies rotatably mounted on respective spindles via respective bearing structures. Each cone assembly may have a respective cutting structure with a minimal moment center located along each respective axis of rotation. Each respective bearing structure has a center point located proximate each respective minimal moment center.
