Electrically insulated bearings protect against bearing damage caused by electrocorrosion — the passage of electrical current. Insulating the bearings with silicon-nitride ceramic eliminates the ...

Electric motors fail more often than they should. Sometimes, it is not the motor’s fault. The real issue lies deep ...

This can drive a current down the shaft, to the bearings, through the frame, and back again through the bearings, as shown in Fig. 1 above. The resulting current isn't localized within the bearings.

Electric motors fitted with VFDs (Variable Frequency Drives) are at risk of bearing damage due to a build-up of current in the shaft. The current discharges through the bearings, damaging the ...

Electric motors fail more often than they should. Sometimes, it is not the motor’s fault. The real issue lies deep ...

To prevent damage from electric current passage, an electrically insulated bearing at the non-drive end is usually used. There are two types of insulated bearings available from SKF: INSOCOAT ...

The SQ77 Series of rolling bearings feature built-in electrical insulation for protection against current discharge and the resulting electrical corrosion. Resources. Members. Directory.
