How does a Bearing Isolator work?


An Inpro/Seal Bearing Isolator is a two part dynamic seal consisting of a stator, press-fitted into the bearing housing, and a rotor, attached to the shaft. The rotor revolves with the shaft, driven by a tightly fitting drive ring that is fixed to the shaft. The rotor and stator form a non-contacting compound labyrinth seal with no wearing parts, ensuring permanent protection.
