Hybrid Deep Groove Ball Bearing 6012 M/HC5C4 provide a bearing function and electrical insulation, virtually eliminates premature bearing failure caused by stray electric currents, electrical insulated bearing can reduce the number of failures and improve the machine uptime, reduce the cost of maintenance.

Hybrid Deep Groove Ball Bearing 6012 M/HC5C4 consist of one inner ring, one outer ring with Aluminuim Oxide Coating, and one piece of machined brass cage, steel balls, Its dimension are the same with normal chrome steel 6012 M/C4 Deep Groove Ball Bearing.

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
    Hybrid bearings are non-conductive and therefore suitable for applications such as AC and DC motors and generators, where electric currents are present.
  • Higher speed capability
    The density of a silicon nitride rolling element is 60% lower than a same-sized rolling element made of bearing steel. Lower weight and inertia translates into higher speed capability and superior behaviour during rapid starts and stops.
  • Long service life
    The lower frictional heat generated in hybrid bearings, especially at high speeds, contributes to extended bearing service life and extended relubrication intervals.
  • High wear-resistance
    Silicon nitride rolling elements have a higher degree of hardness making hybrid bearings suitable under difficult conditions and contaminated environments.
  • High bearing stiffness
    With a high modulus of elasticity, hybrid bearings offer increased bearing stiffness.
  • Reduced risk of smearing
    Even under inadequate lubrication conditions, such as high speeds and rapid accelerations, or where there is an insufficient hydrodynamic film, the risk of smearing is reduced between silicon nitride and steel surfaces.
  • Reduced risk of false brinelling
    When subjected to vibration, hybrid bearings are significantly less susceptible to false brinelling (formation of shallow depressions in the raceways) between the silicon nitride and steel surfaces.
  • Less sensitivity to temperature gradients
    Silicon nitride rolling elements have a lower coefficient of thermal expansion, which means they are more stable over temperature gradients within the bearing and provide more accurate preload/clearance control.

The railway industry never stands still and improvements and performance are developed daily. Together with our customers, we are always aware of the latest trends in the market place and we are committed to staying completely up-to-date to make sure that the very latest developments are integrated into new products.

Drive systems, such as gearboxes and traction motors for railway trains, have to be powerful, environmentally friendly, cost-effective and require very low needs for maintenance. These requirements are much more stringent than those in many other industries, because of the weight of railway vehicles and the long service intervals for high speed trains.
