Hybrid Bearings


Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4), which make the bearings electrically insulating.

Bearing features: Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance, even under difficult operating conditions .When compared to same-sized bearings with steel rolling elements, the benefits of hybrid bearings include:

  • Protection from electric current damage
  • Higher speed capability
  • Long service life
  • High wear-resistance
  • High bearing stiffness
  • Reduced risk of smearing
  • Reduced risk of false brandling
  • Less sensitivity to temperature gradients
