Product Description
The "bonding" durable high-efficiency self-lubricating micro-crystals and extreme pressure particles in INDRON® TSTN realized a good balance of low friction and high wear resistance, where dry start is available. It is suitable for heavy-duty bearings with insufficient intermittent lubrication or risk of adhesive wear.
INDRON® TSTN elastoplastic alloy is an extremely ideal wear-resistant lubricating material, which shows a small volume wear both in dry friction and in medium liquid, and is more durable than other sliding bearing materials.
INDRON® TSTN bearing has excellent performance of self-liquid lubrication and wear resistance, which is widely suitable for guide bearings, thrust bearings, impeller rings, etc. of various water pumps. INDRON® bearings can provide integrated, split, bearing bush, slat bearing bushes, centrifugal coating D and multi-layer PLYDX to meet the needs of various pump types.
Key Advantages
Good balance between low friction and wear resistance.
Integral dynamic bearing surface pressure can reach 10MPa.
Durable self-lubricating particles inside to protect the shaft sleeve.
PV can reach 100MPam/s under the condition of moist water.

Our laboratory is equipped with advanced material performance testing and analysis instruments, allowing us to strictly control every detail of product design and production, ensuring superior product quality. INDRON® bearings, seals, and gaskets are more durable than ordinary bearing materials under various conditions, including dry friction, water lubrication (clean water or water containing sand and mud), non-lubrication, grease lubrication, and even under impact load conditions.

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.
What bearing materials are more suitable as the materials used for water pump guide bearings, Babbitt alloy, rubber, ceramics or new polymer materials? It is advisable to take account of the lubrication requirements, use environment and maintenance cycle of the equipment.

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. |

Working temperature |
≤70°C |
≥273°C |
The bearing itself can withstand the temperature of 1,400°C |

|
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. |

Applications
INDRON® TSTN bearings are widely used in bulk carriers and working ships. It has been proved in practice that the product successfully replaced 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.
