Bearing Fluting damage caused by capacitive shaft voltage discharge via inner to outer bearing race via bearing grease. Shaft voltages produced by Variable Voltage Variable Speed drives systems degradates bearing grease over time resulting in a low resistance path for damaging shaft voltages leading to bearing damage. EARTHRING shaft grounding rings are designed to divert damaging shaft voltages to the motor frame via highly conductive and gold brush clusters, protecting motor bearings.

Shaft Voltages left unaddressed lead to motor bearing failures. It is not uncommon to see values in the region of 25v-30v Pk to Pk on an unprotected motor.

EARTHRINGS Protect electric motor bearings by providing a highly conductive path to earth, ensuring that damaging capacitive discharge voltages are diverted away from motor bearings.
