Eliminate Constant Oil leaks and Continuous Maintenance

The Importance of Bearing Protection

Gearboxes are a significant component in the industrial process and can be found within a variety of industries. Unfortunately, they can be unreliable and difficult to maintain due to constant oil leaks from ineffective sealing solutions. Lubrication loss and contamination ingress into the bearing housing are two of the most common reasons for premature bearing failure on gearboxes, leading to unexpected downtime and high maintenance costs.

A Superior Sealing Solution

Inpro/Seal’s multiple gearbox Bearing Isolator designs are perfect sealing solutions for the variety of gearboxes in your facility. The Inpro/Seal Bearing Isolator is a compound labyrinth seal that keeps contamination out of the bearing housing and lubrication in, significantly increasing gearbox reliability. For non-flooded bearings, with oil levels below the shaft, the non-contacting VB45-U and Double Runner Bearing Isolator designs permanently protect against contamination ingress and lubrication loss. For flooded bearings, with oil levels above the shaft, the STS Bearing Isolator combines Bearing Isolator technology with a contact seal to significantly increase sealing capabilities.
