The VB45-U Bearing Isolator is one of the most robust Bearing Isolators ever developed.

The IP66 rated VB45-U Bearing Isolator provides universal permanent bearing protection against both oil and grease lubrication loss. This unique unitized design handles extreme amounts of axial movement with only a 17.78 mm (0.700 in.) overall length, allowing for premium protection in limited space.

Features and Benefits

  • XX Interface – unique stator/rotor interface provides permanent IP66 rated 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
  • Coalescing Ring – blocks grease from traveling down the shaft into atmosphere
  • D Groove – captures oil on the shaft and returns it to the bearing housing
  • Unitized Stator – accommodates axial shaft movement
  • 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
