VBXX®-D Bearing Isolator

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.

Same day shipments and split designs are available.
