Weyerhauser Uses Isomag Bearing Seals On Sumitomo Paramax 7 Gearbox

In 2015, Weyerhauser Paper (Now IP), was repairing a Sumitomo Paramax 7 gearbox. This double reduction parallel gear drive comes factory equipped d with two lip seals on the high speed shaft and the low speed shaft. These oil seals would wear out in a short time and the forced lubrication system would then but forcing the ISO-220 oil out of the housing.

The customer requested two things of Isomag magnetic bearing isolators, stop the egress of oil, and have a seal that will last the maintenance life cycle goal. Isomag magnetic face seals met both of Weyerhauser's needs and more! Isomag magnetic bearing isolators are a positive seal that also wont damage the shafts of your gearbox like lip seals. They work in horizontal or vertical up or down positions for the right angle gearboxes. Isomag bearing isolators also work perfectly in grease lubrication environments. The end user was able to say goodbye the all the diapers left sitting around their gearbox, and say hello to meeting their planned life cycle for your gearbox with Isomag bearing isolators, which are still running today.
