Dampers control air flow between different locations. In industrial settings, they are essential to many operations and often come into contact with high temperatures. Dampers are also often located in difficult to access areas. These factors mean a maintenance-free, self-lubricating, high temperature bearing material is preferable to a traditional rolling element bearing.
Self-lubricating graphite/metal alloy bearings offer this solution.
Since there is no need to lubricate and re-lubricate, or replace due to bearing seizure as a result of high temperatures, these are bearings with true "install and forget" features.
