Hybrid bearing and carbonitrided bearing for crankshaft applications

Hybrid bearings are made of steel rings and ceramic rolling elements to enhance the wear resistance of the bearings in poor lubrication condition.

In addition to being an electric and thermodynamic insulator, hybrid bearings provide higher speed capabilities and a longer service life.


The ceramic balls provide the folloeing bearing characteristics:

  • Electric insulation properties, which eliminate the risk of damages due to electric currents, even at high frequencies
  • Low thermal transfer
  • High-speed performance thanks to low density and low friction
  • Low wear rate due to high hardness
  • Improved grease life and resistance to seizure
