Best Practices for Mitigating Bearing Currents
The insulated ODE bearing prevents potential current flow through it The shaft brush provides a lower impedance path around the DE bearing The bonding cable between the motor and load creates a lower impedance path around the bearings in the load Conclusion Bearing currents have existed since the induction motor was invented

Schaeffler Current
This type of bearing failure often results in significant downtime production loss and maintenance and repair costs As a more economical solution Schaeffler Current Insulated Bearings exhibit significantly higher resistance to electrical currents when compared to standard bearings
Current
Aug 01 2011Current-Insulated Bearings as a Preventive Measure As a rule it is very difficult to eliminate the causes of bearing voltages that are induced by the motor Nevertheless it is possible to avoid damage to the bearing if the flow of current can either be prevented or at least significantly reduced Many types of current-insulated rolling
Hi
Schaeffler Bearing supports and components make a decisive contribution to the reliability and quality of industrial applications etc We can offer many of these products as current-insulated variants with either a ceramic coating on the rings or ceramic rolling elements to provide optimum protection against damaging current transmission
Bearing currents and how to beat them
The issue results from circulating currents due to inductive coupling (inductive bearing currents) and the solution is to break the current path by using one insulated bearing However recently there have been a few reports of bearing currents in motors with smaller frame sizes – up to around 55 kilowatt (kW) rating – in variable speed
