mini66 Bearing Isolator


mini66 Bearing Isolator

The Inpro/Seal® mini66 Bearing Isolator, the latest innovation in Bearing Isolator technology, is the smallest IP66 rated Bearing Isolator available. With only a 0.375" (9,52mm) overall length, the mini66 protects against both water and dust ingress on applications with very limited space. This unique design exceeds IEEE-841 standards and allows for permanent bearing protection on a wider range of rotating equipment than ever before.

As a non-contacting seal with no wearing parts, the mini66 will provide IP66 performance for the lifetime of your application. All designs are custom engineered and can be manufactured in bronze and stainless steel – making it a perfect fit for washdown and severe-duty environments.
