6004/HC5C3

Hybrid deep groove ball bearing
Hybrid single row deep groove ball bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4), which make the bearings electrically insulating. Deep groove ball bearings are the most widely used bearing type, especially in electric motors. The silicon nitride elements not only provide protection from electric current damage but also, when compared to same-sized bearings with steel rolling elements, provide enhanced bearing performance, extended bearing service life, higher speed capability, high wear-resistance, high bearing stiffness, reduced risk of smearing and false (brinelling, and less sensitivity to temperature gradients. These characteristics make them suitable for use in difficult conditions and contaminated environments.

  • Protected against electric current damage
  • Especially suited for use in difficult conditions and contaminated environments
  • Typical benefits of single row deep groove ball bearings
