An inquiry about low temperature bearings from a Russian oil and gas company

In November 2022, our company received an inquiry about low temperature bearings from a Russian oil and gas company. Details: Model: 6320 low temperature bearing -196 degrees; Brand: TSROL bearing; Inner diameter 100mm, Outer diameter 215mm, Width 47mm, Rated load Cr=160Kn Cor=130Kn, Limit speed 5700r/min.

The main types of low temperature bearings are deep groove ball bearings and angular contact bearings. For example: 6205, 6206, 6207, 632, 6328, 7000CV, 7002CV, 7206AV, 7309AC, etc. Application scenarios: liquefied natural gas pumps, liquefied petroleum gas pumps, liquid nitrogen pumps, liquid oxygen pumps, and other cryogenic liquid pumps. Technical features: Under the condition of extremely low temperature (extreme temperature-197°C): when the limit temperature is required to be -200°C, 6Cr14Mo material can be selected but must be used in a vacuum environment.
