QIBR INSOCOAT electrically insulated on the outer ring deep groove ball bearing 70mm inside x 150mm outside x 35mm wide Prevention of electric erosion in bearings QIBR electrically insulated bearings called INSOCOAT are designed to protect a bearing against electric current passage 68 F (20 C) (thus a bearing temperature of 158 F (70 C) measured on the bearing stationary outer ring or housing washer • Radial bearing: a constant radial load being 5% of the basic static load rating Co • Thrust bearing: a constant axial load being 2% of the basic static load rating Co • Open bearings with Normal clearance

QIBR Current

The QIBR current-insulating bearings can be seen as an upgrade for the standard non-insulated ball bearing with an protection against electric current passage The specifications are therefore identical to the standard deep groove ball bearing e g the 6219-M-J20AA-C3 QIBR has the the same characteristics as the standard 6219-M-C3 QIBR

Electrically Insulated Bearings

NKE electrically insulated rolling bearings reliably prevent current discharge NKE provides bearings with oxide ceramic insulating layers on the bearing ring Applied with plasma technology the insulation has a guaranteed breakdown resistance of at least 1000V AC or DC

Electrically insulated bearings use a special spraying process to spray high-quality coating on the outer surface of the bearing The coating has a strong bond with the substrate and has good insulation performance It can avoid the electric corrosion effect of the induced current on the bearing and prevent the current from affecting the grease

One way to prevent electric corrosion is to use non-conductive ceramic balls in the bearings However this can have a negative effect on productivity Another option is to deploy an insulated housing in the motor but this requires special parts and assembly processes

Both bearings must be insulated or the bearing current effect will be focused on the non-insulated bearing and it will fail twice as quickly We also recommend using hybrid bearings that will offer benefits such as low friction longer re-lubrication intervals and a longer lifetime compared to a standard bearing

AEGIS Bearing Protection

Install one AEGIS Bearing Protection Ring drive end preferred to protect bearings in attached equipment (gearbox pump fan bearing and encoder etc) AEGIS Ring can be installed internally on the back of the bearing cap or externally on the motor end bracket Colloidal Silver Shaft Coating PN CS015 is required for this type of application
