Bearing Isolator : Information

The Original Bearing Isolator

As the inventor of the original bearing isolator, Inpro/Seal continues to be a leading provider of permanent bearing protection for a variety of applications. No matter the size or complexity of the application, Inpro/Seal’s technical experts can design a custom solution for your equipment.

Bearing failures lead to expensive downtime and lost production. With Inpro/Seal Bearing Isolators you can reduce maintenance costs and double the lifetime of your rotating equipment.

The Inpro/Seal Bearing Isolator is a two part dynamic seal consisting of a stator and a rotor attached to the shaft. The rotor and stator form a non-contacting compound labyrinth seal with no wearing parts – ensuring permanent protection.

Keep contamination out. Keep lubrication in.

The Inpro/Seal Bearing Isolator

Patented bearing isolator design features protect in two ways:
  • Lubricant is captured in the inner portion of the labyrinth and flows back to the bearing housing.
  • Outside contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the rotor by centrifugal force and gravity.
Features and Benefits:
  • Non-wearing, non-contacting, permanent bearing protection.
  • Custom engineered for your specific application and operating environment.
  • Split designs for ease of installation.
  • Patented VBX Ring blocks moisture and condensation created by heating/cooling of bearing enclosures.
  • Same day shipments available on most products, including new designs.
  • Unconditional performance guarantee.
