On June 13, 2016, at the EASA Convention and Trade Show, Jeff Clarkin, Inpro/Seal® Market Development Manager, and Robby Tejano, Inpro/Seal Product Engineer, presented The Next Generation of Shaft Grounding at the EASA New Product Theatre. Attended by motor professionals, the presentation discussed bearing damage that occurs through the use of Variable Frequency Drives (VFDs) and how Inpro/Seal’s new Smart Shaft Grounding is a reliability solution through premium bearing protection.
About Smart Shaft Grounding
Stray shaft currents induced by VFDs can discharge through a motor’s bearings and the bearings of coupled equipment, resulting in fluting on the bearing race and causing premature bearing failure. Inpro/Seal Smart Shaft Grounding, featuring the Smart™ CDR®, Smart MGS® and Smart Ground Monitor™, combines proven shaft grounding technology with innovative new features to protect the bearings of VFD-driven equipment.
The Smart CDR uses proprietary conductive filaments to draw stray shaft currents safely away from the bearings to ground. Its unique design utilizes a conductive shaft sleeve to maintain effective conductivity between filaments and shaft surface. For severe-duty applications, the Smart MGS combines Smart CDR technology with the patented VBXX® Bearing Isolator to provide complete bearing protection against shaft currents, contamination ingress and lubrication loss. To ensure maximum protection, the Smart Ground Monitor works with the Smart CDR or Smart MGS to provide instant feedback on shaft grounding performance.
As inventor of the original Bearing Isolator, Inpro/Seal has been delivering innovative sealing solutions and outstanding customer service for more than 30 years. Their unique technologies increase the reliability of rotating equipment and provide real cost savings by improving mean time between repair (MTBR). Inpro/Seal’s superior customer service and streamlined production processes allow for same or next-day shipments on most products, even new designs. Headquartered in Rock Island, Ill., USA, Inpro/Seal maintains a global sales and distribution network to provide responsive, localized support to customers worldwide.
