  • Use precise mounting techniques to avoid any deformation of the bearing rings.

Preload Adjustment

  • Adjusting the preload can help achieve the desired rigidity and reduce play in the bearings. Too much preload can increase friction and wear, while too little can cause excessive play and vibration.
  • Preload can be applied using spring mechanisms, spacers, or controlled axial force during assembly.

Balancing the Rotating Assembly

  • Balance the rotor and the bearing assembly to reduce vibrations. Imbalances can lead to increased vibration levels and reduced accuracy.

Lubrication

  • Use the correct type and amount of lubrication. Over-lubrication can cause excess drag, while under-lubrication can lead to increased wear and noise.
