ABSTRACT:
A sealing arrangement for a rolling cutter designed to protect the antifriction bearings disposed between a support shaft and a rotatable outer body of the rolling cutter. A sealing arrangement is provided comprising at least two seal means located outward from the antifriction bearing of a rolling cutter and further comprising a cavity means between the two seal means so that flushing coolant, fluid or grease may be injected into the sealing arrangement and, when injected, will carry heat, dirt and other contaminants outward and away from the interior of a rolling cutter thereby preventing damage to the antifriction bearings and the seal means located nearest to the antifriction bearings.
