Rolling Bearing Lubriion for Critical Running Conditions

The so-called bearing type value (kf) assumes the actual design of the bearing to be lubried. This factor can have values between 0.9 and 10 for kinematically simple ball bearings. For kinematically complex bearings (like axial cylindrical roller bearings with high sliding friction) the kf factor can reach values up to 90.
