1. Materials for high temperature resistant bearings

When the bearing operating temperature is 120°C, the bearing is called a high temperature bearing.

1. High-temperature bearings made of GCr15 and GCr15SiMn steel need to undergo special high-temperature tempering and dimensional stabilization treatments. As the tempering temperature increases, the material bearing material decreases accordingly, and the bearing load-bearing capacity decreases.

2. High-temperature bearings are made of high-speed steel W18Cr4V, high-temperature bearing steel GCr4Mo4V or stainless heat-resistant steel through overall quenching.

2. Materials for low-temperature bearings

1. Bearings with operating temperatures below -60°C are low-temperature bearings. Mainly used in various types of liquid pumps, such as liquefied natural gas pumps, liquid nitrogen (hydrogen, oxygen) pumps, butane pumps, liquid pumps for rocket missiles, spacecraft, etc.

Commonly used low-temperature bearing structures are mostly single-row deep groove ball bearings and cylindrical roller bearings. Low-temperature bearings are commonly made of stainless steel bearing steel 9Cr18, 9Cr18Mo, and can also be made of beryllium bronze, ceramics and other materials.

2. Working temperature under extremely low temperature conditions (limit temperature -253℃):

When the working limit temperature is -253°C, 6Cr14Mo material can be used, but it must be used in a vacuum environment.

Note: When using low-temperature bearings, attention should be paid to burns caused by poor lubrication, so special attention should be paid to selecting appropriate lubricants.
