International Paper in Prattville, Alabama was looking for a new sealing solution for the bearing housing of their Marathon TVH electric motor. This 365T Frame electric motor was placed in a steamy place in the mill and had trouble with water entering the bearing housing and contaminating the grease lubrication, leading to early failures. The factory installed labyrinth isolators were allowing water to enter through it's leak path.
In 2009, the mill specified Isomag magnetic face bearing seals to completely seal the bearing housings to increase the mean time between failures. Since this installation, Internation Paper has been using Isomag bearing isolators throughout many mills, ensuring a positive sealed bearing housing and increased reliability and performance.
