Isomag Bearing Isolators Extend Bearing Life in Beloit DD4000 Refiner

WestRock Paper in Demopolis, Alabama, was in need of a better bearing protection solution for their Beloit DD4000 paper refiner. Paper refiners are critical in creating uniform paper fibers before being sent off to the paper machine for production. The maintenance team had the Beloit refiner's bearing housing in a flooded condition, and wanted to maintain that, but they needed to replace the lip seals with a bearing seal that could withstand the test of time.

Beloit DD4000 Paper Refiner

Isomag bearing isolators are unique in that they are both a positive seal but also do not damage the shafts on the host equipment like lip seals. The mill was introduced to Isomag bearing isolators through a channel partner in 2015, and are still running today with no issues.
