The VB45-S Bearing Isolator is the new standard in Bearing Isolator technology.

The next step in permanent bearing protection, Inpro/Seal’s latest design provides IP66 protection against contamination ingress and lubrication loss. With only a 15.88 mm (0.625 in.) overall length, the VB45-S™ Bearing Isolator is the best protecting Bearing Isolator in the most compact design available.


Features and Benefits

  • XX Interface – unique stator/rotor interface provides IP66 rated permanent protection against contamination ingress
  • Contamination Chamber – collects contaminants trying to enter the bearing housing and expels them through the expulsion port through centrifugal force and gravity
  • D Groove – captures oil on the shaft and returns it to the bearing housing
  • VB45 Chamber – unique 45° chamber that houses the VBX® Ring and allows for a smaller overall length compared to other designs
  • VBX Ring – blocks the transfer of vapor contamination created by heating/cooling of the bearing enclosure
