Product Description
INDRON® ceramic bearings for pumps, marine, and mining applications, developed by Techemer Corporation, are engineered to meet the rigorous demands of hydro-turbine pumps, marine, and mining environments. These water-lubricated ceramic bearings offer exceptional wear and corrosion resistance, making them ideal for demanding applications beyond the limits of conventional steel bearings.
Our senior material scientists and mechanical engineering specialists have achieved an internationally advanced level in material design, material innovations, material manufacturing, and material applications. As a company focused on customer needs and backed by years of experience and professional expertise, we assist customers in solving their technical problems and provide advanced material technology solutions.
Key Advantages
INDRON® ceramic bearing technology is leading the industry, and its advantages of wear resistance and corrosion resistance are more and more popular in the mining and chemical industries.
Superior Corrosion Resistance
Ceramic materials such as silicon nitride (Si3N4) and zirconium oxide (ZrO2) exhibit excellent resistance to corrosion, particularly in marine environments where exposure to saltwater is common. This ensures prolonged bearing life and reliable performance.
High-Temperature Stability
Ceramic bearings maintain their integrity under high-temperature conditions, preventing cold welding and wear failures associated with high-speed, heavy-load operations. They can operate without pre-lubrication, simplifying maintenance and enhancing reliability.
Reduced Friction and Wear
The inherent properties of ceramic materials result in lower friction coefficients compared to steel, leading to reduced rolling resistance, decreased energy consumption, and extended service life.
Lightweight Design
Ceramic bearings are significantly lighter than their steel counterparts, reducing the overall weight of machinery and contributing to improved efficiency and performance.
Electrical Insulation
The non-conductive properties of ceramic materials prevents electrical currents from passing through the bearings, eliminating the risk of electrical erosion and extending their service life.

Characteristics |
The 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 requirements |
Clean 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 water |
Grease lubrication requires a grease supply lubrication system. |

Application site |
For 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. |

Partial data from THORDON product description
Under the same conditions, INDRON® elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means INDRON® bearing has longer service life, higher reliability and lower maintenance cost.
Applications
INDRON® Ceramic Bearings are particularly suited for:
Hydro-Turbine Pumps
Their ability to operate efficiently in water-lubricated environments makes them ideal for hydro-turbine applications.
Marine Equipment
The superior corrosion resistance of ceramic bearings ensures durability and reliability in marine environments, where exposure to saltwater and harsh conditions is prevalent.
Water-Lubricated Systems
The self-lubricating properties of ceramic materials make these bearings suitable for systems where traditional lubrication is challenging or undesirable.
Mining Industry
Ceramic bearings, with their high hardness, low friction, and excellent corrosion resistance, are widely used in key mining equipment such as crushers, conveyors, vibrating screens, slurry pumps, and large electric motors. Their wear resistance, high-temperature capability, and electrical insulation significantly enhance equipment reliability and extend service life.
