Shintech found Isomag bearing isolators to be the perfect solution for their Lufkin MD 912 gearbox. This double reduction parallel shaft speed reducer was used as n elevator and experienced problems of ingress of dust and moisture into the bearing housing, eventually causing the gearbox to fail. The one weakness of this Lufkin gearbox is the lip seals that are installed. Oil seals wear out in about 6-8 months on continuous use. Then the contamination of the bearing house starts. On top of that, the lip seal wears a grove into the shaft, making it necessary to either refurbish the shaft or get a new one when it's time to repair.
When Shintech specified Isomag bearing isolators for their gearbox in 2014, they were very happy with their decision. The Lufkin gearbox has been running leak free and contamination free since then.
