Product Description TSTN Hydro Turbine Guide Bearing - Self-Lubricating, Water-Lubricated Solution & Thordon SXL AlternativeThe TSTN guide bearing is made from INDRON? TSTN elastoplastic alloy, offering excellent self-lubricating and water-lubricated performance. Compared to conventional guide bearings, it significantly reduces starting torque, protects both shaft and bushing, extends system life, and serves as a reliable alternative to Thordon SXL bushings.

It is advisable to take account of the lubrication requirements, use environment and maintenance cycle of the equipment Bearing 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 Why Choose INDRON? Bearing Bushing? Eco-Friendly LubricationWater serves as the primary lubricant, eliminating the risk of water contamination caused by lubricant grease leakage.Durable and Maintenance-FreeMade from elastic-plastic alloys bonded with lubricative particles, INDRON? bearings can withstand impulsive and edge loads. They support dry start-up and are designed for maintenance-free operation.Exceptional Wear ResistanceOptimized for balanced friction and outstanding abrasion resistance, the bearings effectively disperse wear particles to protect the shaft surface from damage.Customized SolutionsTailored material formulations and bearing designs are available based on specific operational conditions and equipment requirements.Certified QualityISO 9001:2015 certified, Techemer remains committed to customer-centric innovation and uncompromising quality standards.Company ProfileTechemer Composites (Guangdong) Co., Ltd., founded in 2008 and based in Guangzhou, China, is a high-tech enterprise integrating R&D, manufacturing, and sales.
