Bearing Seals, or Bearing Isolators are non-contact, non-wearing, permanent bearing protection devices that isolate your bearing environment. A MARQUE Bearing Seal consists of a Rotor and a Stator that act in tandem in both static and dynamic environments to prevent outside contamination into and loss of lubrication out of the bearing enclosure.

Use of MARQUE Bearing Seals can increase the service life of your bearings and other mechanical components of the rotating equipment by 7 years or more. Tested to withstand a differential pressure of 250mm on a water column, MARQUE Bearing Seals can be used in several rotating equipment such as process pumps, electric motors, gearboxes, split pillow blocks, fans, and turbines.
