The materials of high temperature bearing

High-temperature bearings are made from a variety of materials, each with unique benefits and suitability for specific applications. The main materials used include ceramics, steel, hybrid configurations, and high-performance polymers.

 

Ceramic bearings

Merit:

High temperature resistance

Corrosion-resistant

Low density

Non-conductive

General Applications:

 

Used in aircraft engines and other aerospace components.

Use equipment that requires cleanroom conditions.

For use in medical devices that may require autoclaving.

Stainless steel bearings

Merit:

 

It has high strength and good hardness

It has excellent corrosion resistance.

It has good wear resistance under load capacity and is not easy to deform.

General Applications:

 

In the automotive industry, it is preferred for components exposed to corrosive elements.

They are used in industrial machinery for heavy machinery or food processing machinery.

Hybrid bearings

Merit:

 

Hybrid bearings typically have ceramic balls in combination with a steel inner and outer ring. This configuration combines the high load capacity of steel with the low friction and high temperature resistance of ceramic.

General Applications:

 

In electric motors, it is used in applications where high speed and heat generation reduction are critical.

In high-speed machinery, it is suitable for applications that require durability and reduced maintenance.

Polymer bearings

Use of high-performance plastics:

 

These include polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), and other fluoropolymers that maintain strength and stability at high temperatures.

General Applications:

 

The food industry, due to its non-toxic, corrosion-resistant properties, is often used in processing equipment.

Chemical processing for environments where chemical resistance and reducing the risk of contamination are important.

Common applications for high-temperature bearings

High-temperature bearings are critical in many industrial and technical environments where operation involves high temperatures that standard bearings cannot withstand. Here are some common applications based on the ability of high-temperature bearings to operate in extreme conditions:

 

Aerospace: Jet engines, spacecraft components, auxiliary power units

Automotive: exhaust systems, turbochargers, engine components

Steel mills: continuous casters, furnace doors, rolling mills

Energy production: gas turbines, coal-fired power plants, nuclear reactors

Chemical processing: reactors, pump processing, high-temperature fluids, compressors

Manufacturing equipment: injection molding machines, high-temperature ovens, kilns

Food processing: ovens, deep fryers, food packaging machinery

 

temperatures. In practical applications, high-temperature bearings are often used in aerospace, automotive engines, steel production, chemical and other fields. Equipment in these areas often needs to operate for long periods of time in high-temperature environments.
