Isomag Bearing Isolators: The Best Seal For SEW Eurodrive Gearbox Bearing Housings

SEW Eurodrive gearboxes are found on oil refineries, drilling platforms, chemical plants and paper mills. Most companies run them to failure, which often times is an impressive 10+ year run before a repair is needed. A customer needed to stop their gearbox , running a conveyor belt, from leaking in the woodyard. The weakness was the double lip seals that are installed. They wear out in about 6-8 months on continuous use. 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. Regular labyrinth isolators don't scar the shaft but perform poorly in forced lube systems or flooded environments.
