In 2011 a International Paper in Eastover, South Carolina was repairing a Cleveland Gear AF gearbox. This double reduction worm drive gearbox comes factory equipped with two lip seals on the high speed shaft and the low speed shaft. These oil seals would wear out in a short time causing an ingress of water and an egress of lubrication from the gearbox. This Cleveland AF gearbox is running the water skimmer in their water treatment tanks, so keeping both the gearbox and the water clean is critical. The customer requested two things of Isomag bearing isolators, stop the egress of oil, and have a seal that will last the maintenance life cycle goal.
