Bearings: Tribological Components | GGB

High loads call for bearings with increased contact area and high load bearing capacity. Bearings with solid lubricants are designed to operate at higher temperatures than those lubried with oil or grease. And high speed appliions call for special lubricants to minimize heat build-up and friction.

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.
