INSOCOAT bearings
INSOCOAT bearings are designed to prevent electric current from passing through the bearing The external surfaces of either their inner or outer ring are coated with an insulating aluminium oxide layer by applying a sophisticated plasma-spray process for an outstanding quality finish The solutions are very cost-effective compared with other
Electrically insulated bearings
ELECTRICALLY INSULATED BEARINGS These bearings can be designed with: A insulated fitted plates or B electrical insulation of the complete outer diameter For both types of bearings GTW uses only materials with the highest-graded mechanical and electrical properties Technical

White Paper: Detection of electrical discharges in bearings
Once electrical erosion is diagnosed whether it comes from the high or low frequency currents several actions can be taken before bearing damage results by means such as: • Using insulated bearings like QIBR INSOCOAT bearings for either both bearings or just non-drive end bearing (NDE) to open the low frequency current circulating circuit

Electrically insulated bearings from QIBR
Electrically insulated bearings from QIBR The problem of stray electric current bearing damage When a stray current in an electric motor uses a bearing as its path to ground bearing damage can occur The most common causes of stray electric currents are: asymmetry
The purpose of insulated bearing for Motors with VFD
Dec 09 2015The best method for mitigating bearing currents is to use hybrid bearings in both ends of the motor as insulated bearings (in both ends) is often not enough to withstand the capacitive bearing currents introduced by a VFD Insulated bearings are unfortunately often very costly compared to a rather similar performance using common mode chokes
Current
of electrically insulated bearings at the planning stage As a result customer benefit is increased through reduced maintenance costs and higher machine availability Normally it is sufficient to interrupt the circuit between the housing and shaft in order depending on the application to insert current-
