Abstract

An earth boring bit has a bit body (13) with at least one bearing pin (15). A cone (16) is rotatably mounted on the bearing pin (15). A seal assembly (19) is located between the cone (16) and the bearing pin (15), the seal assembly (19) having at least one flexible seal member (25,31). A flexible pressure compensating diaphragm (17) is mounted in the body (13). The diaphragm (17) has one side adapted to be exposed to borehole fluids and another side in contact with lubricant contained in bearing spaces between the cone (16) and the bearing pin (15). The flexible seal member (25,31) and the diaphragm (17) are, formed of a fluprinated elastomer. The elastomer is either a perf luoroelastomer (FFKM) or a f luoroelastomer (FKM).
