Randall offers graphite fill on all groove styles and drilled hole parts.

Graphite fill is used in grooves and drilled holes for its self-lubricating properties. Graphite fill is a perfect fit for bushings that see intermittent use or are utilized in a low-speed environment where the RPMs necessary for an oil film to form are not present. Graphite also works well in high-RPM environments as it will provide lubrication during start up and shutdown and during sudden shock load situations.
