Product description:

ROSCHEN Rock Bit Sealed Journal Bearing Tricones are designed for truly important projects and can withstand vast amounts of wear and tear. The floating bushing acts as a self-lubricant helping to reduce friction, and dissipate heat under heavy load conditions. This means our Journal Bearing Tricones can stand up to extremely prolonged and deep drilling sessions with minimal time spent on maintenance or tending to debris.
