New Magnetic Bearing Isolator from Inpro/Seal  

Inpro/Seal, the inventor of the bearing isolator, continues its legacy of developing innovative, reliable sealing products to prevent bearing failure with the introduction of a new magnetic bearing isolator. Utilizing magnetically energized faces to create a liquid-tight seal, it protects against lubrication loss and contamination ingress in challenging applications such as flooded, high oil splash or oil mist lubrication environments. 

“The VBMag Bearing Isolator combines decades of knowledge and engineering expertise to deliver a reliable, long-lasting, leak-free seal for a variety of challenging applications,” said Chris Solfelt, product manager. “The addition of VBMag expands Inpro/Seal’s product portfolio, allowing us to better support our customers with the best bearing protection solution for any application.”

The isolator eliminates typical shaft wear making it a preferred solution for applications that historically used elastomeric lip seals which can wear quickly at the point of contact and damage the shaft. Designed for long-term performance, it reduces the need for unscheduled downtime and maintenance costs.

The VBMag bearing Isolators are IP66 rated to meet high industry standards for bearing protection. Precision-lapped faces energized by rare earth magnets create a liquid-tight seal suitable for a wide variety of applications. The innovative design allows the maximum amount of lubrication to reach the faces, which provides optimum conditions for a long sealing life. 

Inpro/Seal is part of Dover Precision Components, an integrated provider of performance-critical solutions for rotating and reciprocating machinery. Headquartered in Downers Grove, Illinois, Dover Precision is also the parent company of Waukesha Magnetic Bearings. For more info, see
