Lignum Vitae North America, LLC. offers a time-proven EPA / ABS compliant water-lubricated bearing technology. With over a 160 year service record in vessels from workboats to icebreakers and submarines, our bearings will not smear or seize onto the shaft as plastic or composite materials often do. Lignum vitae bearings effectively replace composite, plastic, bronze and oil filmed bearings. Contact us to determine the best bearing for your vessel.
