INDRON® self-lubricating bushing are widely used in bulk carriers and working ships. It has been proved in practice that the product can successfully replace metal stern bearings and rudder bearings in ship oil lubrication systems. Compared with other non-metal stern bearings and rudder bearings in the water lubrication system, the product has a longer service life, which helps ship owners to save a great bunch of costs and increases the reliability of stern bearing and rudder bearing systems.
