The
Inpro/Seal Bearing Isolator
 The Inpro/Seal Company manufactures a Bearing
Isolator that will provide the highest level of bearing
protection available. Inpro/Seal® Bearing Isolators are made
of high quality bronze and are designed to last for at least
100,000 hours compared to the common lip seals which usually
fail after only 3,000 hours. With the latest engineering and
manufacturing technology Inpro/Seal can meet your reliability
requirements with seals designed specifically for your
equipment with quick, timely deliveries.
This two-part dynamic seal consists of a
stator press-fitted into the bearing housing and a rotor
attached to the shaft. The rotor and stator form a
non-contact, compound labyrinth, so there is nothing to wear
out.
It protects two ways:
 |
Bearing 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 stator by
centrifugal force and gravity |
