Isomag Bearing Isolators in Pulp & Paper

January 18, 2017

Isomag bearing isolators solve bearing contamination issues in vertical pulper gearboxes for paper mills across North America.


The input shaft of vertical pulper gearboxes in paper mills see pulp build-up that is typically removed by heavy wash-down operations. This leads to inevitable bearing contamination. A paper mill in the U.S. addressed this problem and approached Isomag for a solution. The result was a custom Isomag MD V8-XL pulp shearing seal. Since installed in 2015 the customer no longer sees bearing failure in these vertical pulper gearboxes.
