Sea Water Lubricated Stern Tube Bearings, Self Lubricating

Marine Bearing INDRON® bearings 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.What bearing materials are more suitable for use in self-lubricating bearings? It is advisable to consider the lubrication requirements, environmental conditions, and equipment maintenance cycle.COMMON GUIDE BEARING MATERIALSBearing typeINDRON bearingAR bearingCeramic bearingRubber bearingBabbitt alloy bearingCharacteristicsThe performance is close thordon, which can use more equipment assembly methods. In addition to traditional installations by freezing and pressurizing. It can also be installed by coating reactive thermal polymerization Dx and cold sticking.Good wear resistance and impact resistance. The bearing hardness is high; the shaft sleeve is easy to wear; the temperature difference changes greatly; there will be the risk of shelling; the price is high.Wear-resistant, heat-resistant, corrosion-resistant, lubricated by pump circulating water, capable of dry grinding for a short time, high requirement on accuracy in processing and assembly, fragile and the most expensive.It has a long history and mature manufacturing process, featured by wear resistance, anti-seismic, impact resistance, convenient assembly/disassembly and low price (only 20% of ceramic bearings price)Wear resistance and impact resistance require a set of more complicated sealing and lubricating devices and mechanisms.Lubricating requirementsClean water can be used for lubrication or 150s dry start according to the material grades.Dry start more than 180S without clean water lubrication.It can be lubricated by pumping medium without special clean water lubrication.Clean industrial waterGrease lubrication requires a grease supply lubrication system.Working temperature≤70ºC≥273ºCThe bearing itself can withstand the temperature of 1,400ºC≤50ºC≤65ºCShort time up to 80ºCApplication siteFor pumping stations short of clean water or pumping stations requiring short-term dry friction, hRBR grade is suitable for water quality with moderate sediment content.Pumping stations without clean water or pumping stations requiring dry friction of more than 180S.Pumping stations without clean water or pumping stations requiring short-term dry friction.Extensive application in any pumping stations with clean water sources.The liquid of the pump itself cannot be used for bearing lubrication in the pumping station.Bearing typeINDRON bearingAR bearingCeramic bearingRubber bearingBabbitt alloy bearing    /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
