Bearing Seal Applications

ISOMAG magnetic-face bearing isolators use superior face seal technology to protect the bearings on thousands of centrifugal machinery applications around the world.

The most common ISOMAG bearing seal applications include any scenario where rotating parts are in use — including electric motors, gearboxes, pumps and steam turbines. Our bearing seals are designed for no-contact magnetic sealing, requiring no additional lubrication so that contaminants and moisture stay out, while lubricant — whether oil or grease — stays intact.

Bearing lubrication sealing applications extend to all situations where the following benefits are desirable:

  • Longer equipment life
  • Fewer equipment breakdowns
  • Longer time between maintenance and repairs
  • Lower overall equipment costs

In contrast to lip seals, which last only a few months and cause additional wear and tear on your valuable machinery components from the moment they are installed, magnetic-face seals do not wear on the host equipment and can stay in service for up to 75,000 hours of operation.

The specific ISOMAG bearing seal we recommend is driven largely by the customer’s equipment application and the type of lubrication system in the machine.
