Aegis Bearing Protection Rings SGR-1.125-UKIT-1A4 Rings

The Aegis SGR-1.125-UKIT-1A4 is a professional-grade shaft grounding ring engineered to eliminate damaging electrical currents in VFD-driven motors. Designed for 1-1/8 inch (1.125") shafts, specifically for NEMA 182T and 184T frame sizes, this bearing protection ring utilizes proprietary Electron Transport Technology. By providing a low-impedance path to ground, it effectively prevents bearing fluting and pitting caused by electrical discharge, significantly extending the operational life of industrial motors. This Aegis split ring model (identical to the SGR-1.125-1A4) features a convenient bolt-on design that allows for rapid field installation without the need for motor disassembly or shaft decoupling. Constructed with a durable aluminum housing and high-density conductive microfibers, it ensures 360-degree circumferential contact for continuous protection. This HVACR motor grounding solution is essential for maintaining system reliability and reducing unscheduled maintenance downtime in commercial and industrial applications.

• Universal Compatibility: Specifically designed for NEMA frame 182T and 184T motors with a 1.125-inch shaft diameter.
• Easy Retrofit: The split-ring design enables fast installation in the field without disassembling motor components or couplings.
• Precision Grounding: Features conductive microfibers that provide millions of contact points to safely divert shaft voltages.
• Enhanced Durability: Prevents VFD-induced bearing damage, reducing the risk of premature motor failure and costly repairs.
• Maintenance-Free: Engineered for long-term performance under various environmental conditions without the need for regular adjustment.

How does a shaft grounding ring prevent bearing failure?
Variable frequency drives (VFDs) induce high voltages on motor shafts. Without a grounding path, these voltages discharge through the bearings, causing pitting and fluting. The Aegis SGR provides a path of least resistance, safely channeling these currents to the motor frame and ground.

Can I install the SGR-1.125-UKIT-1A4 without taking the motor apart?
Yes. This model is a split-ring version, which means it can be opened and placed around the shaft, making it ideal for retrofitting existing motors in the field without removing the load or disassembling the unit.

Is the UKIT version different from the standard SGR?
The UKIT-1A4 includes a universal mounting kit with multiple bracket styles, screws, and conductive epoxy options, ensuring it fits a wide variety of motor end-bracket configurations.
