Fitted Journal Bearing
Types of Lubrication
BEARING LUBRICATION
Lubrication reduces friction. It also prevents wear and corrosion,
and guards against
solid and liquid contamination. Theoretically, a properly
lubricated bearing operating
under ideal conditions will last forever. This is not possible in
reality, of course. But a
properly lubricated bearing has the best chance of achieving its
maximum service life.
