Baldor Electric Motor Sealed With Isomag Magnetic Face Seals

February 7, 2019

Petrobras in Brazil, was in need of a different bearing isolator on their Baldor M1713T Electric Motor. They needed to eliminate the stray mist issues they were having with the factory installed labyrinth isolators that would escape through the leak path. Stray mist creates an oil slick covering surrounding the equipment and walkways, causing unsightly housekeeping and safety issues on slippery walkways. Oil mist bearing lubrication systems are used extensively throughout this refinery, and this was a growing pain point for the maintenance team.  

 

 A sales representative from John Crane introduced the refinery to Isomag magnetic face bearing isolators as the perfect solution to their growing problem. Isomag magnetic bearing isolators eliminate stray oil mist because they are a positive seal. In addition to providing superior sealing and protection functionality the Isomag bearing isolators offer:

  • A high level of MTBR – projected operating life of 100,000 hours at 12,000 sfm (60 mps)

  • Low operating temperature – does not increase the operating temperature of the bearings

  • Easy installation and removal – O-ring fit on the OD of the Isomag bearing isolator makes it easy to install and if necessary remove and reinstall.

Since the installation in 2010 the customer has reported that the stray oil mist issue has been alleviated and the motors in the unit have cooler bearing housings.
