High temperature bearings

High Temperature Bearings are bearings that are specifically designed to operate in environments outside of the normal bearing operating temperature range. Conventional bearings are typically designed to operate in temperatures ranging from -20°C to 120°C, while high-temperature bearings are able to maintain performance and reliability in more extreme temperature conditions, typically 150°C to 350°C. °C or even higher. High-temperature bearings are designed not only with thermal resistance in mind, but also with consideration for how to deal with material expansion caused by high temperatures, lubrication issues, and other related thermodynamic and chemical stability issues.

 

Advantages of high-temperature bearings:

High-temperature bearings are able to operate in extreme temperature conditions without failure and are temperature resistant.

High-temperature bearings are designed to resist degradation and deformation caused by high temperatures, making them more reliable than ordinary bearings.

High-temperature bearings are often manufactured using special materials and lubricants.

High-temperature bearings can reduce the overall energy consumption and operating costs of the machine.

The use of suitable high-temperature bearings reduces the risk of equipment failure and increases production safety.

The design of high-temperature bearings is flexible and has a wide range of applicability.

 

Types of high-temperature bearings

High-temperature bearings can be roughly divided into two categories according to their structural design and use: standard structural bearings and special structural bearings.

 

Standard structural bearings

It is usually made of chromium steel or stainless steel, which has good high temperature resistance within certain limits. High-temperature grease is often used in lubrication to maintain performance at high temperatures and prevent friction and wear.

 

Special construction bearings

Advanced materials such as ceramics, graphite or high-performance polymers, which have good resistance to thermal expansion and abrasion, are often used.

 

The difference between high-temperature bearings and ordinary bearings

The main difference between high-temperature bearings and ordinary bearings is their ability to operate at extremely high temperatures without loss of performance. This capability is largely due to the special materials and designs used in high-temperature bearings. For example, high-temperature bearings may be made of high-temperature resistant ceramics, special steels or high-performance polymer materials that can withstand temperatures up to 1000°C or even higher, while ordinary bearings are usually made of materials such as carbon steel or ordinary stainless steel that can only withstand temperatures of 1000°C or higher. It can withstand temperatures of about 250°C.

In addition, high-temperature bearings are designed to take into account changes in thermal expansion, chemical stability and mechanical strength at high temperatures, so special internal structures and lubrication systems are often used to adapt to the challenges posed by high
