ABSTRACT:
This invention consists of a floating spindle cap disposed between a spindle pilot bearing extending from a main journal bearing and a cone bore formed by a rotary rock bit cone secured to the journal bearing. The floating spindle cap is formed from a softer material than both the spindle bearing and the cone to accommodate for slight misalignments and edge loading between the journal bearings and the cone while working in a borehole.
