The mini66 Bearing Isolator is the smallest IP66 rated Bearing Isolator available.

With a 9.52 mm (0.375 in.) overall length, the Inpro/Seal mini66 Bearing Isolator protects against both water and dust ingress on grease lubricated applications with limited space. This unique compact design exceeds IEEE-841 standards and allows for permanent bearing protection on a wider range of rotating equipment than ever before. A non-contacting seal with no wearing parts, the mini66 Bearing Isolator provides IP66 performance for the lifetime of your application.

Features and Benefits

  • Innovative Rotor/Stator 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
  • VBX® Ring – blocks the transfer of vapor contamination created by heating/cooling of the bearing enclosure and acts a restrictor band to eliminate grease loss
  • Compact Design – 9.52 mm (0.375 in.) overall length makes it the smallest IP66 rated Bearing Isolator on the market
