Inpro Seal Bearing Isolators

System and Bearing Protection

Inpro/Seal is a world leader in the design and manufacturing of permanent bearing protection and complete shaft seals for rotating equipment. Since 1977 Inpro/Seal has delivered innovative sealing solutions that improve the reliability of rotating equipment around the globe.

Patented bearing isolator design features protect in two ways. Here’s how…

  • 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

The Inpro/Seal Bearing Isolator is a unique barrier for contamination ingress and lubrication retention for bearings installed in:




Pillow blocks

Steam turbines

Sleeve-bearing motors

Paper machine rolls,

 and many other types of rotating equipment.

No matter the size or complexity of your application, Inpro/Seal can design an isolator to fit your specifications.
