Saving Energy By Using Bearing Isolators

What are bearing isolators and why use them:

The bearing isolator is a non-contacting labyrinth seal and was originally invented in 1970s. It is a mechanical device that is used to ensure that a bearing is isolated from its environment that allows the bearing to be properly lubricated. Here the bearing isolator provides a permanent bearing protection and eliminates the need for continual maintenance. Since bearing isolators ensure that there is no contact between the unitized rotor and stator there is no consumption of energy. It also means that these isolators never wear out and have long life spans. Another variant has O-rings being used for creating seals. Bearing isolators are usually made out of bronze or other metals. They also have a vapor blocking system that prevents the free transfer of vapor contamination when the equipment is cycled on or off.
