Reliable bearing protection and extended MTBF with the Thomson QXE Bearing Isolator.

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.

  • Expels contaminants
  • Eliminates lubrication leakage
  • Protects against water ingress

The QXE maximizes bearing life and significantly reduces operations costs, save on:

  • Lubricants
  • Oil changes
  • Labor and overtime
  • Bearing replacements
  • Equipment failures
  • Down time

QXE Bearing Isolator Product Range:

  • QXE - For standard mount applications.
  • QXE-GB - For gearboxes where a positive seal is required due to flooded conditions.
  • QXE-PB - For pillow block housing specifically fitting the groove for the LER/LOR ring.
  • QXE-TB - For steam turbines where steam is coalesced before it reaches the bearing housing.
