Abstract

A rolling element assembly includes a rolling element rotatable about a rotational axis when positioned within a cavity defined on a bit body of a drill bit, and a compliant retainer positioned within a retainer slot defined in the bit body. A biasing device is positioned within a device pocket defined within the bit body to bias the compliant retainer against the outer circumferential surface of the rolling element. The compliant retainer secures the rolling element within the cavity while an arcuate portion of the rolling element protrudes from the cavity and exposes a full axial width of the rolling element.
