Electro Static Technology (AEGIS®) guarantees that AC induction motor bearings will not fail from electrical fluting damage when AEGIS Shaft Grounding Rings have been installed with new bearings in accordance with our recommended best practices, as published in the AEGIS® Bearing Protection Handbook.

  • The AC induction motor must meet the conditions listed below and new bearings must be installed at the time of AEGIS Ring installation for the warranty to be approved.
  • For repaired motors or for field installations: Upon registration and approval the warranty shall be for 2 years from the installation date of the new motor bearings and AEGIS Ring.
  • For new motors with AEGIS rings installed by the motor manufacturer: Upon registration the warranty shall be for a 2 year period after the motor manufacturer’s bearing warranty ends.
  • If electrically induced bearing fluting damage occurs, EST will pay the current Vaughen’s National Average Price for “Furnish/Install 2 Standard Ball Bearings” and will supply a new shaft grounding ring (SGR or PRO as appropriate) and AEGIS colloidal silver coating (CS015). The warranty shall apply to any AC induction motor whether new or repaired which conforms to the AEGIS Bearing Protection Handbook’s best practices.
