Aegis Bearing Protection Rings SGR-48-UKIT-2A4 Rings

The Aegis SGR-48-UKIT-2A4 is a premier shaft grounding ring solution specifically engineered for 48mm motor shafts. This split-ring kit is essential for HVACR motor protection, as it effectively mitigates VFD-induced shaft voltage that causes destructive bearing fluting and pitting. Utilizing conductive microfiber technology, the Aegis SGR-48-UKIT-2A4 provides a low-impedance path to ground, redirecting harmful electrical discharges away from the motor bearings. This universal mounting kit is designed for high-performance VFD-controlled motors (NEMA or IEC frames), ensuring long-term operational efficiency and preventing premature equipment failure in commercial and industrial settings. Its split-design allows for easy retrofitting on existing installations without requiring the removal of the motor coupling or external equipment, making it a favorite for speed-critical preventative maintenance.

Key Benefits:

• Complete Bearing Protection: Redirects harmful currents to prevent electrical discharge machining (EDM) and bearing failure.
• Universal Compatibility: Includes uKIT universal mounting brackets to fit 48mm shafts on almost any motor end-bracket.
• Durable Split Design: High-quality aluminum construction with a split ring for fast, non-invasive installation.
• Zero-Maintenance Operation: The patented FiberLock™ channel secures microfibers for years of reliable grounding without further adjustment.
• Enhanced HVAC Efficiency: Optimizes the reliability of motors driven by variable frequency drives in air handling and cooling systems.

Common Questions:

How do I know if I need a shaft grounding ring?
If your motor is controlled by a variable frequency drive (VFD), it is susceptible to induced shaft voltages that destroy bearings. Installing an Aegis SGR is the industry-standard preventative measure for these systems.

Can the SGR-48-UKIT-2A4 be installed without taking the motor apart?
Yes, the split-ring design specifically allows you to install the protection ring around the 48mm shaft without disconnecting the motor from its load.

What is included in the SGR-48-UKIT-2A4 kit?
The kit contains the split shaft grounding ring, four styles of universal mounting brackets, and all necessary metric and SAE hardware for various mounting configurations.
