Inpro Seals / Bearing Isolator
A bearing Isolator is a two-part dynamic seal consisting of a stator and a rotor working in conjunction to form a non-contacting compound labyrinth seal – with no wearing parts. However our bearing isolators consist of 3 parts: the cap, inner and outer ring for better performance.
Our Inpro Seal / Bearing Isolator are manufactured in three parts; the inner ring rotates with the shaft driven by a tightly fitting drive ring. It also has an outer ring component that is fixed to the bearing housing with a press fit and O-ring gasket. The three pieces are assembled into a single unit and axially locked together by O-rings. There is no mechanical contact between the inner and outer ring while the Isolator is running. The cap is shrink-fitted to the outer ring; to serve its purpose by holding the inner and outer ring together.
The purpose of the bearing isolator / inpro seal is to keep out leakage and contamination of the oil inside the bearing housing and to keep out dust/dirt from outside the bearing housing which improves the life of the bearing to full potential.
Bearing lubricant is captured in the inner portion of the labyrinth and directed back into the bearing housing.
