Electro Static Technology: Bearing Protection Ring
March 14, 2011
The Aegis™ SGR bearing protection ring protects the bearings of VFD-driven motors from electrical damage, and the Aegis universal mounting kit (U-Kit) simplifies its mounting on virtually any ac motor shaft. The kit includes the Aegis grounding ring and mounting hardware for most motor designs. Ordered based on the NEMA “u” shaft diameter, the kit contains the correct size ring for the motor and four styles of brackets with bolts and lock washers that can be used in various configurations, depending on the contours of the motor’s end bracket. The ring prevents electrical “fluting” damage in the bearing, bearing noise, costly motor repairs/replacements, and downtime by safely channeling VFD-induced bearing currents to ground.
