INPRO/SEAL

Modern equipment outfitted with variable frequency drives (VFDs) is more energy-efficient, but it can also be more vulnerable to damage. VFDs create high-frequency shaft voltages that look for a path to ground. When the insulating properties of the lubricant break down, these voltages discharge through motor bearings or the bearings of connected equipment. The result? Wear patterns like pitting, fluting, and frosting that eventually lead to premature bearing failure, increased maintenance costs, and unexpected downtime.

Inpro/Seal’s Shaft Grounding solutions offer an effective, long-term solution by safely redirecting these damaging currents away from the bearings and toward the ground. Built with smart engineering and trusted performance, this technology helps protect your motors, improve equipment uptime, and extend the life of your systems.

With a product line that meets industry-recognized standards, including NEMA MG1 31.4.4.3 and CSI 23 05 13. Inpro/Seal delivers robust, maintenance-friendly solutions designed to work across a wide range of applications.
