INDRON® TSTN is a high-performance self-lubricating and wear-resistant material, specifically designed for heavy-duty applications such as water pump guide bearings, marine rudder bearings, and stern bearings. Its unique elastoplastic alloy combines micro-crystalline structures with high-efficiency anti-pressure particles, achieving an exceptional balance of low friction and high wear resistance. It performs reliably even under dry-start conditions or insufficient lubrication.
Self-Lubricating and Wear-Resistant:
INDRON® TSTN incorporates durable self-lubricating particles, offering low wear in both dry friction and medium liquid environments, surpassing traditional sliding bearing materials in durability.
Dry-Start and Lubrication Flexibility:
Designed to withstand insufficient or intermittent lubrication, the material effectively prevents adhesive wear, making it suitable for challenging operating conditions.
Outstanding Load-Bearing Capacity:
The dynamic surface pressure can reach up to 10 MPa, supporting high-load operations with ease.
Versatile Applications:
Ideal for guide bearings, thrust bearings, impeller rings, and more across various types of pumps. Available in multiple configurations, including integrated, split, bush bearings, centrifugal coatings, and multi-layer structures, to meet diverse customer needs.
Eco-Friendly and Highly Durable:
The material delivers superior performance and longevity under various conditions, including muddy water, clean water, non-lubrication, and impact loads, reducing maintenance costs and improving reliability.

| 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 | ≤50°C | ≤65°C Short time up to 80°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. |
