摘要：	When a 9,280 hp. workboat returned to service following extensive repairs at the James Marine Pa-ducah River Service yard in Kentucky, it marked the first application of Thor-don's new seal-embedded bearing to an articulating rudder. Articulating rudders are unlike conventional rudders and can be more costly to repair when things go wrong. They are more susceptible to wear and tear, due to their higher operating pressures and abrasives, and as a result, they require a more robust bearing and seal solution. For one marine transportation service provider in the United States, however, a key requirement was a grease-free bearing capable of increasing the intervals between drydockings and reducing operational costs. To meet the requirement, Thordon engineers recommended a bearing using the company's proven ThorPlas-Blue material, a better material for articulating types of rudders, and integrating a Thordon lip seal into the design. "We found that by embedding a lip seal into the bearing, we could better prevent ingress of river water, sand, silt and debris, which would otherwise rapidly wear the pins and bushigs down, reducing the workboat's in-service time," said Kasey Cummings, technical sales manager for Thordon Bearings.
