Friction bearing
- Nose and outer bearing replaced by friction bearing
Bearing lubrication
- Bearing classified as sealed or non sealed
- Non sealed are lubricated by mud system through the face where the cone meets the journal
- Sealed are lubricated by custom made system built within the leg body
- Lubrication by mud is generally recommended
- Sealed bearing consists of bearing, seal, reservoir and pressure compensator
- The seal is an O-ring type placed at the contact between the cone and the bearing lowermost point
- The reservoir provides lubricants (special grease) to the bearing through a passageway in the leg
- Pressure compensator has a flexible diaphragm operates within a metal protector
- Maintains equal pressure inside and outside bearings
- Equipped with a pressure relief valve
- It protect the bearing seal when heat cause breakdown of grease into gaseous components
