Self-Lubricating Bearings

Hydro

Our machinable self-lubricating Karon liner systems have become an important component in the operation of hydropower systems around the world due to their high performance and reliability. KAron-lined bearings in power generating Kaplan turbines, wicket gates, lock system gates, and critical sector and radial gates in flood control applications eliminate normal maintenance downtime and higher actuator loading associated with traditional greased bronze bearings and other bearing materials. The absence of secondary grease or oil lubrication and no use of graphite in their construction also make KAron bearings environmentally friendly in sensitive waterways.

Our onsite, full service Test and Development Lab can support most development or qualification tests that may be needed for your bearing application. If your test requirements fall outside of our internal capabilities, we can utilize our network of trusted, third party test facilities to provide the performance data that you require.
