This enables our team of over 35 design engineers to work closely with each customer to design and implement application-specific bearing solutions including shaft bearings and pintle bearings, made from bearing bronze. Our self-lubricating bearing technology is found around the globe in applications such as navigational lock systems, power generation systems, steering & diving mechanisms, and watertight hatches & doors.

Self-Lubricating Bearings for Marine

Self-Lubricating Bearings


Over the past few decades, the self-lubricating Karon liner systems have been a critical component in commercial and military marine systems around the world due to their high performance and reliability. KAron bearings offer low friction and low wear in military and commercial marine applications such as watertight doors, rudders, and deck support systems. KAron bearings have also been used in marine infrastructure projects such as crane systems and ferry terminal passenger and vehicle ramps.

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.
