VB45-U Bearing Isolator

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.
