A system that can include a centralizer configured to be radially positioned between a tool and an internal bore of a tubular, wherein the centralizer is configured to engage the internal bore and the tool via a plurality of biasing devices circumferentially spaced away from each other about a center axis of the centralizer. A method can include installing a biasing device in a plurality of protrusions that extend radially outward, extending a portion of each biasing device past an outer radial surface of a respective protrusion to engage a tubular, and extending a portion of each biasing device past an inner radial surface of a central bore of the centralizer to engage a tool, where the first portion and the second portion are configured to substantially align a center axis of the tool with a center axis of the tubular when the tool is installed in the tubular.
