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.

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

Applications

The Inpro/Seal Bearing Isolator is a unique barrier for contamination ingress and lubrication retention for bearings installed in pumps, motors, gearboxes, 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.
