Grease lubrication mechanisms in rolling bearing systems | Evolution Onli

Phases in grease lubrication Grease lubrication is a dynamic process that can be divided roughly into three phases, as shown in fig. 1. After the initial filling or during relubrication, the grease will be located between the rolling elements, leading to high churning ...

Thin Layer Flow in M.T. van Zoelen - Universiteit Twen

SUMMARY To extend the service life of rolling element bearings lubricant such as oil or grease is used. The lubricant significantly reduces the wear of the steel surfaces, provided that the lubricant is able to form a sufficiently thick film to separate the surfaces in the ...
