Product Description
Maintenance-Free Bearing
INDRON® Maintenance-Free Ceramic Bushings are advanced ceramic bearing solutions specifically designed for demanding environments such as mining, where extreme wear, corrosion, and temperature conditions challenge traditional metal bushings. These bushings are fully customizable and integrate cutting-edge materials and structural innovations to deliver long-lasting, lubrication-free performance in abrasive, high-load conditions.
Key Advantages
Maintenance-Free Operation
● Self-lubricating design with no need for oil or grease.
● Capable of dry starts, eliminating cold welding even under high load and high speed.
● No external lubrication or cooling system required.
Exceptional Wear and Corrosion Resistance
● Made from high-hardness silicon carbide (SiC) ceramics and super-hard alloys.
● Resistant to strong acids, alkalis, and abrasive media—ideal for mineral slurry and chemically aggressive environments.
High Mechanical Strength and Structural Reliability
● Superior hardness (Knoop 2700–2800), compressive strength up to 7900 MPa.
● Designed with a cushioning elastomer layer that absorbs vibration, compensates for misalignment, and protects the ceramic sleeve from impact-related damage.
Thermal Shock and High-Temperature Stability
● Withstands temperatures up to 1500°C without loss of hardness or mechanical integrity.
● Excellent thermal conductivity reduces heat buildup, extending service life.
Customized for Mining Equipment
● Tailored to fit various mining applications, including pumps, conveyors, crushers, and agitators.
● Dimensions and configurations can be customized to suit unique system requirements.
Technical Structure
Our ceramic bearing structure consists of:
Ceramic Bushing (Silicon Carbide)
Ultra-hard, wear-resistant, and corrosion-proof.
Dual-Layer Shaft Sleeve (Stainless Steel + Hard Alloy)
Provides high sliding performance and wear resistance under water lubrication.
Cushioning Layer (German NDI Elastomer)
Damps vibrations and protects ceramic components during operation and installation.
Reinforced Housing (Cast Iron/Stainless Steel)
Robust support structure with integrated coolant flow channels for temperature control and shock absorption.

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 |
≤70ºC |
≥273ºC |
The bearing itself can withstand the temperature of 1,400ºC |
≤50ºC |
≤65ºC |
|
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.
