VBXX®-D Bearing Isolator

 INPRO / SEAL bearing isolator is a moisture-proof non-contact type labyrinth seal. It consists of a rotor and a stator, and the two components are fixed by a moisture barrier ring in combination. There is no friction during operation.

To permanently protect against contamination ingress and lubrication loss in oil-lubricated applications, Inpro/Seal sets the standard in Bearing Isolator technology, with the VBXX-D bearing Isolator.

The VBXX-D Bearing Isolator utilizes multiple features to ensure effective and permanent bearing protection. The unique stator/rotor design of the XX Interface blocks contaminants from entering the bearing housing. The D Groove protects against oil loss by capturing oil on the shaft and returning it to the bearing housing. The VBX® Ring inhibits the transfer of vapor contamination created by the heating/cooling of the bearing enclosure.

The VBXX-D Bearing Isolator can be custom engineered to meet the requirements of your application and operating environment.
