Automation levels in distribution centers are low but rising - VFDs are useful in automation because of how precisely they can control motors - VFDs cause electrical bearing damage and premature failure in unprotected motors - AEGIS Shaft Grounding Rings protect motors from electrical bearing damage, and so protect distribution centers from unplanned downtime. AEGIS Rings come with a [2-year extended warranty](https://www.est-aegis.com/product/extended-warranty/) against bearing fluting damage. No other form of protection against VFD-caused bearing damage offers a warranty like this.
