Bearing Lubriion Tips & Mistakes You Might Be Making

Grease is typically applied with special equipment that deposits the grease between the balls, which forces it inside and around the ball or roller raceway interface. Unlike oil, grease is normally denoted as a percentage (e.g. 30% fill), which represents the actual grease volume compared to the free internal space inside the bearing.
