BASF found Isomag magnetic bearing seals to be the perfect solution for their Westignhouse 75R36376 gearbox. This triple reduction parallel shaft speed reducer was used as an 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 Westinghouse 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 BASF specified Isomag bearing seals for their gearbox in 2011, they were very happy with their decision. The Westinghouse gearbox has been running leak free and contamination free since then.
