Type and material of bearing temperature high

The maximum temperature that a bearing can withstand is an important indicator of its normal operation. In general (made of GCr15 bearing steel), the maximum temperature of the bearing is 50 degrees Celsius at room temperature. In special circumstances, the bearing temperature can reach over 120 degrees Celsius, and some may even reach over 150 degrees Celsius.

Bearing temperature high:

There are many types of high-temperature bearings, and different types of bearings can be installed according to different needs and environments.

Bearing temperature high category

High temperature bearings can be divided into ordinary high-temperature bearings and special high-temperature bearings in terms of structural technology.

Bearing temperature high usage environment

High temperature bearings are widely used in high-temperature operation machinery such as metallurgy, kilns, glass, blast furnaces, spray painting equipment, etc.

What materials are used for bearing temperature high

Using heat-resistant bearing steel, also known as high-temperature bearing steel. This type of steel has sufficiently high high-temperature hardness, high-temperature wear resistance, high-temperature contact fatigue strength, oxidation resistance, and high-temperature dimensional stability.

The current application of bearing temperature high mainly includes the following three categories:

(1) Cr4Mo4V (M50) steel is a high-performance heat-resistant bearing steel with high hardness and fatigue life at high temperatures. It is mainly used in aircraft engines and can work for a long time below 315 ℃, and can be used up to 430 ℃ in a short time;

(2) Cr15Mo4 steel has high hardness and corrosion resistance in the range of 260-280 ℃, and can be used to manufacture corrosion-resistant bearings working below 480 ℃, such as for jet engines and missiles;

(3) 12Cr2Ni3Mo5 (M315) is a widely used high-temperature carburized bearing steel, suitable for working below 430 ℃, and can be used to manufacture high-temperature bearings with complex shapes and impact resistance.

General bearing temperature high work at around 300 to 600 degrees Celsius environment
Zirconia bearings at around 600 to 900 degrees Celsius
Silicon nitride bearings can reach temperatures above 1200 degrees, which is currently the highest temperature resistant bearing in the world
