Maritime Fluid Sealing Inc. is an authorized distributor of Inpro Bearing Isolators. Inpro invented the bearing isolator and is the world leader in bearing seal technology. What is a bearing isolator? Basically, it is a non-contacting, non-wearing, permanent solution to keeping the lubricant contained and contamination out of bearings. Inpro/Seal Bearing Isolators are designed to last for the life of the equipment and do not damage shafts like conventional lip seals.

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; and 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.

Some Basic Inpro/Seal Applications







Bearing Isolators are easy to install on virtually any shaft. Damaged shafts do not need to be repaired in order to retrofit Inpro/Seal Bearing Isolators. There's even a split seal for large shafts to simplify installation. Inpro/Seals are widely applied in the Severe Chemical, Pulp & Paper and Hydrocarbon Industries, just to name a few.

Pumps, motors, fans, blowers, steam turbines, gearboxes, pulverizers, pillow blocks, conveyors, precision machine tool spindles, centrifuges and other varieties of rotating industrial equipment require effective and permanent bearing protection. Whatever the application, 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. Compare this to lip seals, which usually fail after only 3,000 hours.
