Thomson QXE

The Thomson QXE Bearing Isolator combines proven labyrinth technology with an innovative expeller design. The QXE is a true, non-contact bearing isolator utilizing double vertical internal chambers. Centrifugal force adds energy to contaminants, deflecting them away from your housing while effectively retaining lubrication. Two static internal coalescing o-rings exclude vapor ingress by breaking it down and directing it to the contamination exclusion chambers. The QXE can be split for ease of installation.
