The AEGIS SGR-3.375-UKIT-1A4 Bearing Protection Split Ring is a heavy-duty, precision-engineered grounding solution designed to protect large electric motor bearings from electrical discharge damage caused by variable frequency drives (VFDs). Built for 3-3/8" (3.375") shaft diameter motors with 444T, 445T, 447T, and 449T frame sizes, this split-ring version allows for quick, non-invasive installation without removing couplings or disassembling the motor. It safely diverts shaft currents to ground, eliminating bearing fluting and extending motor life in demanding industrial environments. Key Features Split-ring design enables fast, easy retrofit installation Protects bearings from electrical discharge and fluting damage Designed for 3-3/8" (3.375") shaft diameter motors Fits NEMA 444T, 445T, 447T, and 449T frame motors Ideal for large, VFD-controlled motor systems Maintenance-free operation with long-term reliability Durable aluminum housing with conductive microfiber technology Includes universal installation kit with mounting hardware and conductive grease Specifications Part Number: SGR-3.375-UKIT-1A4 Brand: AEGIS Type: Bearing Protection Split Ring Shaft Diameter: 3-3/8" (3.375") Motor Frame: 444T, 445T, 447T, 449T Material: Aluminum housing with conductive microfibers Application: Shaft grounding for motors powered by variable frequency drives (VFDs) Installation: Split design allows for quick field retrofit without motor disassembly Compatible Models: Ideal for 3-3/8" shaft motors (444T?449T frame) from Baldor, Marathon, Leeson, WEG, Siemens, and ABB ? and more.
