Premature motor failure is one of the common concerns with electric motors, which can impact productivity and cause frequent downtime. To prevent this, it may be ideal to use quality seals and rings, which help eliminate shaft currents that are detrimental to your electric motor.
Typical issues with motor bearings include fluting damage, severe pitting, fusion craters and severe bearing noise, which often lead to failure and malfunctioning. These are all problems that arise once there is too much resistance of the bearing lubricant, which is due to excessive electrical voltages on the shafts of AC and DC motors caused by Variable Frequency Drives (VFDs).
The AEGIS® SGR Bearing Protection Ring prevents electrical bearing fluting damage by safely diverting harmful shaft voltages and bearing currents to ground. Using proprietary Electron Transport Technology™, the conductive microfibers™ inside the AEGIS SGR provide the most reliable current diversion technology for shaft grounding with a "path of least resistance" to dramatically extend motor life.
An effective means of minimizing maintenance expenses is by using Inpro/Seal bearing isolator, a product that also aids in extending the lifespan of the rotating equipment. The isolator features a stator, and there is a rotor connected to the shaft. As a result, a solid labyrinth seal is created, and this prevents wearing of the parts for optimum protection. Moreover, unnecessary downtime and bearing failures are prevented, and you can achieve greater efficiency in your business operations.
