Aegis Bearing Protection Rings SGR-65-UKIT Rings

The Aegis Bearing Protection Rings SGR-65-UKIT is a professional-grade solid shaft grounding ring engineered to eliminate electrical bearing damage in AC and DC motors. Designed for a 65mm shaft diameter, this uKIT utilizes patented conductive microfiber technology to provide a low-resistance path to ground, effectively preventing bearing fluting and pitting caused by VFD-induced shaft voltage. By neutralizing harmful electrical discharges, it significantly extends the operational life of motor bearings in HVACR and industrial applications.

This electrical bearing protection system features a solid ring design and includes a Universal Mounting Kit with four bracket styles, ensuring compatibility with a wide range of NEMA and IEC motor frames. The high-performance SGR-65-UKIT is optimized for VFD-driven motors, offering a maintenance-free solution that remains effective regardless of temperature or humidity. Precision-engineered for reliability, the Aegis SGR is the industry standard for safeguarding 65mm motor shafts against premature failure.

Key Benefits:

• Superior Protection: Diverts damaging VFD shaft currents away from bearings to prevent electrical discharge machining (EDM).
• Universal Compatibility: Includes multiple bracket styles to fit NEMA 56 to 449T and IEC 132M to 355M motor frames.
• Advanced Technology: Employs 360-degree FiberLock™ Channel conductive fibers for consistent grounding.
• High Durability: Solid aluminum construction designed for long-term performance in demanding HVACR environments.
• Increased Uptime: Reduces the risk of catastrophic motor failure and unplanned maintenance by protecting internal components.

Common Questions:

• Why does my VFD-controlled motor need a grounding ring? Variable Frequency Drives induce shaft voltages that can arc through bearings; the SGR-65-UKIT provides a safe path for this current.
• Can this be installed on an existing motor? Yes, the uKIT is designed for external mounting on both new and existing 65mm shafts.
• Does the solid ring design require motor disassembly? For the solid ring version, the shaft end must be accessible or the motor decoupled for installation over the shaft.
